The Kevin’s Car Care Guide To Custom Wheels

Your browser does not support video

If you’re interested in customizing the wheels and tires on your sedan, there are a few things you should know first.

Most importantly, the wheels you buy need to fit your vehicle. Not all wheels are created equal. Too many Barnhart motorists have bought a set of wheels that caught their eye, then, after going to the work of mounting them, have found that the wheels don’t fit right and the tires rub against the sedan when they turn or go over a bump.

To ensure a proper fit, you can consult with your Kevin’s Car Care tire professional. He/she can also help you find tires that are suited to your driving habits as well as your sedan. You may find their auto advice invaluable, and you’ll probably be happier with your new wheels once you purchase them.

But if you just have to have that set of wheels, and you’re willing to pay for them, you can modify your vehicle to fit the wheels. Again, you should seek a knowledgeable St. Louis professional’s help ahead of time. For example, if you want a bigger set of wheels on your pickup truck, you can get a suspension lift so they will fit the truck. A professional Barnhart custom wheel shop can help you get the work done right.

The anti-lock brakes and stability control system on your sedan are engineered to work with a particular height of tire. This is another reason drivers should be careful when purchasing custom wheels in Barnhart. The new wheel and tire combo needs to match the height of the tires that came with your vehicle.

Your car’s computer gauges your speed by the revolution of your tires and sends commands to the brakes and traction control based on that speed. If you put larger or smaller tires on your sedan, your computer is calculating the wrong speed and, consequently, sending incorrect commands to the brakes and traction control. This can have serious consequences as it may result in costly damage to your vehicle or, worse, an accident.

If you change the size of your wheels, you need to get your engine’s computer reprogrammed at Kevin’s Car Care to accommodate the new tire size. New wheels shouldn’t just fit your vehicle, they should also fit your lifestyle. There are hundreds of styles and sizes to choose from. You should do a little research about which wheels and tires will best fit your personality, give you the performance you want, and meet your handling needs. We’re not saying you shouldn’t personalize your ride, we just want you to be happy with the result. Talk to us at Kevin’s Car Care in Barnhart.

After all, good car care isn’t just about preventive maintenance. It’s also about making good choices.

When Are Your Tires Worn Out?

Hey St. Louis, are your tires worn out? What is the standard for our Missouri streets? How can you tell on your sedan?

While there may be legal requirements for the St. Louis area, there are safety concerns that go beyond meeting minimum replacement mandates.

2/32 is the depth of the tire tread wear indicator bars that US law has required to be molded across all tires since August 1, 1968. When tires are worn so that this bar is visible, there’s just 2/32 of an inch – 1.6 millimeters – of tread left. It’s that level of wear that’s been called into question recently.

We’re referring to the Consumer Reports call to consider replacing tires when tread reaches 4/32 of an inch, or 3.2 millimeters. And the recommendation is backed by some very compelling studies.

The issue is braking on wet surfaces in and around St. Louis. Most of us think of our brakes doing most of the work, but if you don’t have enough tread on your tires, the brakes can’t do their job. When it’s wet or snowy, the tread of the tire is even more critical to stopping power.

Picture this: you’re driving over a water covered stretch of road near St. Louis, Missouri. Your tires must be in contact with the road in order to stop. That means that the tire has to move the water away from the tire so that the tire is actually contacting the road and not floating on a thin film of water.

Floating on the surface of water is called hydroplaning. So if there’s not enough tread depth on a tire, it can’t move the water out of the way and you start to hydroplane.

In the study a section of a test track was flooded with a thin layer of water. If you laid a dime on the track, the water would be deep enough to surround the coin, but not enough to cover it.

A car and a full-sized pick-up were brought up to 70 miles per hour, or 112 kilometers an hour and then made a hard stop in the wet test area. Stopping distance and time were measured for three different tire depths:

  • New tire tread depth
  • 4/32 of an inch
  • 2/32 of an inch

So what happened with the 2/32 tires on the car? Get this – when the car had traveled the distance required to stop with new tires, it was still going 55 miles an hour. Stopping distance was nearly doubled to 379 feet and it took 5.9 seconds.

Wow! That means if you barely have room to stop with new tires, you would hit the car in front of you at 55 miles an hour with the worn tires.

Now, with the partially worn tires – at 4/32 of an inch – the car was still going at 45 miles an hour at the point where new tires brought the car to a halt. It took nearly 100 feet more room to stop and 1.2 seconds longer. That’s a big improvement. We can see why Consumer Reports and others are calling for a new standard.

Of course, stopping distances were greater for the heavier pick-up truck.

How do you know when your tires are at 4/32 of an inch? Easy; just insert a quarter into the tread. Put it in upside down. If the tread doesn’t cover George Washington’s hairline, it’s time to replace your tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.

You may remember doing that with pennies. A penny gives you 2/32 to Abraham Lincoln’s head. The quarter is the new recommendation – 4/32.

How do people feel about replacing their tires earlier? Well, tires are a big ticket item and most people want to get the most wear out of them that they can. But do you want that much more risk just to run your tires until they are legally worn out?

For us, and we would guess for many, the answer is “no”.

Buying the Right Tires and Wheels In Barnhart Missouri

Everyone in Barnhart Missouri eventually replaces their tires, whether it’s because they’re worn out or they’re just looking for something different. There are so many great tire choices in Barnhart Missouri, it can be difficult to sort them out. Let’s group the broad spectrum into several categories that will help in the selection process.

One category is often referred to as “summer tires”. Summer tires are designed to be driven on the road when temperatures are generally above 45 degrees. Their tread design is optimized for traction on dry roads in Barnhart Missouri and they’re also able to effectively displace water on rainy roads.

Barnhart Selecting Tires and Wheels Now the rubber compound gets a little hard and stiff as temperatures drop below 45 degrees as it occasionally does here in Barnhart Missouri. And the tread which handles dry roads so well, can get packed with snow or mud – which provides very little traction in those conditions.

So if you live where its summer all year round, these tires will work well for you. If you like maximum performance in warm weather, but still live where it gets cold and snowy, you’ll want to change your summer tires for winter tires as the weather starts to change.

Summer tires can be purchased with an emphasis on handling performance, smooth ride or long life. Your Barnhart Missouri tire professional at Kevin’s Car Care can help you find the right tire for the way you drive.

As you can imagine, winter tires are designed to work very well in snow and ice. Their tread is designed with many channels and grooves that throw the snow out of the tread as the wheel turns. This means the tire is always be able to bite into the snow.

The rubber compound used in winter tires is specially formulated to be flexible at temperatures below 45 degrees. This maximizes cold weather traction. When it gets warmer, the softer rubber will wear faster on warm dry pavement than summer tires, so change them out once the weather has turned.

There’s a range of tires within the winter tire category. If you live where there’s a lot of snow and ice, look for the mountain and snowflake icon that signifies a severe snow rating. If you have milder winters and still want a performance component, they make a winter tire for you as well.

For many people, an all-season tire is the answer. You will give up some of the performance at the extreme ends of the summer tire/ winter tire spectrum, but you will find a long wearing tire that gives both good highway performance and winter traction on our Barnhart Missouri roads.

Within the all-season category, there are many choices that you tire advisor can help you evaluate.

Outside of these three main categories, some people in Barnhart with trucks and SUVs like a tire that is designed for both on-highway and off-highway use. They can handle the rocks and bumps off-road, but still work well on the street. Again, many options depending on the relative emphasis on on-road verses off-road.

You may want new wheels to go with your new tires – well, there are hundreds and hundreds of styles to choose from. That’s a matter of personal taste. If you want to change the size of your wheels and tires, do get some professional help.

The computers on your vehicle are programmed to the size of wheel and tire combination that comes from the factory. Tire size affects various computer controlled functions like anti-lock brakes, traction and stability controls, speedometer and odometer. Of course, you want these systems to work properly. The computers can be re-programmed for different tire sizes.

And if you want to increase the size of your wheels and tires, you’ll want so help to make sure they’ll fit in the wheel wells of your vehicle without rubbing during turns or over bumps.

The Kevin’s Car Care Guide To Tire Specs

You know you need new tires, but you’re not sure what type. You look at a tire to get the size: 225, 50, R, 16, 92, H. All the way to the Barnhart service center you keep repeating it over and over. You even say it over in your mind while waiting in line. Then you get to the counter and the manager asks what size you need. Then your mind goes blank.

Tire size can be confusing for many Barnhart drivers. There’s so much on the side of the tire, and it’s hard to keep straight.

Even though there’s a lot on a tire – if you know what it all means, it’s actually more helpful than confusing for Barnhart tire shoppers. Let’s start with the size number.

For example, let’s say a tire reads: 225 50 R 16 92 H. The 225 part is the width of the tire in millimeters – the width between the sidewalls of an inflated tire with no load. The 50 is the aspect ratio – the ratio of the sidewall height to the tread width. Off-road tires will have a higher number and high performance tires will have a lower number.

The R signifies it’s a radial tire. And 16 is the rim or wheel size in inches.

The 92 is the load rating index – it’s the load carrying capacity of a tire. The higher the number, the more it can safely carry. Your empty sedan can be safe with a lower number, but you’ll need a higher rating if you routinely haul heavy loads around Barnhart. The next letter is the speed rating. Not all tires sold in Barnhart are speed rated. The ratings generally follow the alphabet: the further up the alphabet, the higher the speed rating – with the exception of H – it comes between U and V (don’t ask why).

There’s a lot of fine print that most St. Louis drivers probably need a magnifying glass to read. But there are a couple of other large print items of interest. One is the tread type: highway, mud and snow, all season, severe snow, etc.

And then there’re the Uniform Tire Quality Grading System markings. The first is a tread wear index. 100 is the base line – a lower number is poorer and a higher number is better. All things being equal, a tire rated 200 would wear twice as long, on a government test track, than one rated at 100. These wear grades are only valid within the auto maker’s product line – Barnhart drivers can’t compare with other auto makers. And it’s vital to note that a lower rating might be just what you want – a high performance, sticky tire has a softer rubber compound and won’t wear as long, but boy, will it take those corners on twisting Missouri roads.

The next is a traction grade. This measures the tire’s ability to stop on wet pavement in government tests. A – the best, B – intermediate, C – acceptable.

Temperature grade measures a tire’s resistance to heat build up in government tests. A, B and C – from best to acceptable.

It’s safe for Barnhart drivers to go with the vehicle manufacturer’s original equipment recommendations that came on your car. But if you want to make adjustments, you’ll now be better equipped to communicate with your trustworthy Kevin’s Car Care tire professional.

Fuel Saving Tip: Tire Pressure Saves Fuel In Imperial

Under-inflated tires waste gas for lots of folks in the Imperial area. Think how hard it is to walk in sand – you just have to work harder because of the resistance. When your tires don’t have enough air in them, their rolling resistance is dramatically increased and it simply takes more gas to get from Barnhart to Imperial.

Barnhart Tire Pressure Always check your tire pressure when you gas up at one of our local Imperial service stations. If they’re low – even just a little bit – bring them up to proper pressure. There’s a sticker on the inside of your driver’s door that gives the manufacturer’s recommended tire pressure.

And don’t rely on your tire pressure monitoring system to alert you to when you need more air. The TPMS system is set to warn you when pressure drops twenty percent below recommendations. That’s severely under inflated and you needed more air a long time ago. And if you have a slow leak – get it fixed right away at Kevin’s Car Care.

Get some air and save some gas.

Selecting New Tires and Wheels

Some of us just love tires. All those little rubber hairs on new tires and the smell is wonderful. We live in a great time for tires. No matter how you drive, where you want to go or the look you’re after; there is a tire for you.

The same is true about wheels. The hardest part is choosing from the thousands of wheels available.

We may not be able to help with that, but we can help you get some things in mind before you consult with your Barnhart tire professional. Let’s start with function and think about how you drive.

For example, maybe you have a large SUV but you don’t drive off-road, so an off-road tread isn’t important. Also, because you are not out bouncing over rocks in the Missouri backcountry, you don’t need a high profile tire to protect your rims. So that means you can probably go with the low-wide look.

If you have a winter season with rain and snow or if you find you need better ice and snow performance, they make great, high-performance snow tires that won’t make it look like you are driving a tractor.

There really are a lot of options for any given vehicle. You will find it very helpful to have a discussion like this with your St. Louis tire pro when you need new tires. You can find the best solutions for your driving needs and to make improvements in ride or handling.

Picking a wheel that is the same size as what you are now running is pretty simple. But, it gets trickier if you want to upsize. Just get some help when you go bigger. All that tire and wheel still needs to fit in the available space. You do not want your tires to rub when you turn or hit a bump. You also need to make sure your brakes and suspension bits will fit with your wheel of choice. It doesn’t matter how great your car looks if it’s not drivable.

Taller, wider wheels and tires probably weigh more than your stock shoes. And it’s “unsprung” weight – that has a big impact on brake performance. The upsized shoes increase rotational inertia – if you go too big you may need to upgrade your brakes to compensate.

Another possible problem is an inaccurate speedometer. This happens because the number of rotations can change with the new wheels. Fortunately, speedometers and odometers are all controlled by the engine computer; so it is simple to get it reprogrammed and compensate for the bigger tires.

No matter what you are after: low cost, long life, high performance, traction or stunning good looks, your wheel and tire professional at Kevin’s Car Care in Barnhart, Missouri can help you identify your needs and give you a custom fit. With all the options available, you don’t have to compromise. There is a tire out there with your name on it!

St. Louis Safety Systems: Tire Pressure Monitoring System

Flats, blow outs, skids and longer stopping distances can all be the result of St. Louis drivers driving around on under-inflated tires. Admittedly, it’s hard to tell when a radial tire is under-inflated. If your manufacturer recommends 35 pounds of pressure, your sedan tire’s considered significantly under inflated at 26 pounds. The tire may not look low until it gets below 20 pounds.

New laws required vehicle manufacturers to include a Tire Pressure Monitoring System – or TPMS system – in all cars and light trucks by the 2008 model year. The system has a dashboard mounted warning light that goes off if one or more of the tires falls 25% below manufacturer’s pressure recommendations.

St. Louis Safety Systems: Tire Pressure Monitoring SystemThis technology has been used by St. Louis race car drivers for years. They are able to head off problems from under inflation by closely monitoring tire pressure on the track. It’s up to your sedan’s manufacturer to determine which of many TPMS systems available they’ll use to comply with the law.

Obviously, all of this doesn’t come free for St. Louis drivers. U.S. government studies have estimated the net costs. Of course, the TPMS system itself will cost something. Maintaining the system will have a cost, replacement of worn or broken parts and tire repair cost increases.

The costs are partially offset by improved fuel efficiency and longer tire life. There’s also a potential savings in property damage avoided and fewer travel delays. The net cost is estimated to be between $27 and $100. The government predicts fewer fatal accidents. They estimate that it will cost between three and nine million dollars for every life saved.

Your safety has always been a priority at Kevin’s Car Care. We want you on the road and accident free. We’ve traditionally provided things like tire rotations, snow tire mounting and flat fixes at a very low cost. We’ve been able to quickly and cheaply provide the service, and pass the low cost on to you as an expression of our good will.

That’s why we’re concerned about how you’ll perceive the changes that this new law requires. Every time a tire is changed: taken off to fix a flat, a new tire installed, a snow tire mounted; the Kevin’s Car Care service technician is now going to have to deal with the TPMS system.

Even a simple tire rotation will require that the monitor be reprogrammed to the new location of each tire. When a car battery is disconnected, the TPMS system will need to be reprogrammed. TPMS sensor batteries will need to be changed and failed parts replaced.

Like all other Barnhart service centers, here at Kevin’s Car Care we’ve had to purchase new scanning equipment to work with the TPMS sensors and to update expensive tire change equipment to better service wheels equipped with the new monitoring systems. Our Kevin’s Car Care service technicians have been thoroughly trained on many systems and new tire-changing techniques. All of this adds up to significantly increased cost to perform what was once a very inexpensive service for you.

So when you start so see the cost of tire changes, flat repairs and rotations going up at Kevin’s Car Care, please keep in mind that it’s because of government mandated safety equipment. We want to keep you safely on the road – and we’re committed to doing it at a fair price. This new safety equipment will help you avoid the most common types of vehicle failure in St. Louis, and possibly a catastrophic accident.

All About Your TPMS In Barnhart

Barnhart drivers know that under-inflated tires wear out more quickly. Under-inflation is also a major cause of tire failure for Missouri auto owners. More flats, blow outs, skids and longer stopping distances are all results of under-inflated tires.

It’s hard for many Barnhart drivers to tell when a radial tire is under-inflated. If your car maker recommends 35 pounds of pressure, your tire is considered significantly under-inflated at 26 pounds. The tire may not look low until it gets below 20 pounds.

Uncle Sam to the rescue! A recent federal law required auto manufacturers to include a Tire Pressure Monitoring System – or TPMS system – in all vehicles. The system is a dashboard mounted warning light that goes off if one or more of the tires falls 25 % below the vehicle manufacturer’s pressure recommendations.

The law covers all passenger cars, SUVs, mini vans and pick-up trucks. The system must also indicate if it has a malfunction. This technology has been used in race cars for years. They are able to head off problems from under-inflation by closely monitoring tire pressure on the track. It’s up to your car’s auto manufacturer to determine which of many TPMS systems available they use to comply with the law.

Obviously, all of this doesn’t come free. Government studies have estimated the net costs. Of course, the TPMS system itself will cost something. Maintaining the system will have a cost, replacement of worn or broken parts and tire repair cost increases. The net cost is estimated to be between $27 and $100.

The costs are partially offset by savings in fuel and tread wear. There is also a saving in property damage and travel delay. Also, the government predicts fewer fatal accidents. They estimate there will be between $3,000,000 to $9,000,000 for every life saved.

Your safety is our priority at Kevin’s Car Care. We want you on the road and accident free. We’ve traditionally provided things like tire rotations, snow tire mounting and flat fixes at a very low cost. We’ve been able to quickly and cheaply provide the service, and we pass the low cost on to our valued Barnhart clients as an expression of our good will. That’s why we’re concerned about how you perceive the changes that this new law has required.

Every time a tire is changed: taken off to fix a flat, a new tire installed, or a snow tire mounted, the service professional now has to deal with the TPMS system. Sensors need to be removed and reinstalled. The sensors have to be reactivated after the change. And, unfortunately, the very act of changing the tire damages some sensor parts from time to time – it’s inevitable and can’t be avoided.

Even a simple tire rotation requires that the monitor be reprogrammed to the new location of each tire. When a car battery is disconnected, the TPMS system needs to be reprogrammed. TPMS sensor batteries must be replaced periodically along with failed parts.

Barnhart service centers have purchased new scanning equipment to work with the TPMS sensors and updated expensive tire change equipment to better service wheels equipped with the new monitoring systems.

Missouri service specialist have been trained on many systems and new tire-changing techniques. All of this adds up to significantly increased cost to the service center to perform what was once a very inexpensive service. So if you’ve noticed the cost of Barnhart flat repairs, tire changes, and rotations going up, please keep in mind that it’s because of government mandated safety equipment. Your Barnhart service center just wants to keep you safely on the road – and it’s committed to do so at a fair price. Rememer, this change will help you avoid the most common vehicle failure, and possibly a catastrophic accident.

Barnhart Missouri Winter Prep Service For Your Auto

When winter approaches in Barnhart Missouri, we break out the sweaters, coats, boots and mittens. We want to be ready for winter conditions. Your vehicle needs to be ready for winter as well. The last thing you want is to get stranded out in the cold. You need your vehicle to be safe and reliable. It’s a good idea to get caught up on any neglected maintenance items anytime – but the stakes are higher in the winter.

There are some specific things that we need to do in Barnhart Missouri to have our vehicle ready for winter. The most obvious is having the antifreeze checked. If the antifreeze level is too low, it can’t properly protect your engine, radiator and hoses from freezing. If your car does not seem to be making enough heat to keep you warm, your antifreeze level may be low or you could have a thermostat problem. Get it checked out. If you are due for a cooling system service, now is a perfect time to have it done.

In the cold months around Barnhart we always worry about being able to stop in time when it’s slick out. The first thing to remember is to slow down and allow yourself plenty of room to stop. Of course, you want your brakes to be working properly. A thorough brake inspection will reveal if the pads or any other parts need replacing. Check with your service consultant to see if it is time to replace your brake fluid. It accumulates water over time which really messes with your stopping power.

It is a really good idea to have your battery tested. A battery’s cranking power really drops with the temperature. If your battery is weak in the fall, it may not be up to winter. There is nothing like a dead battery in a snow storm.

Which leads us to an emergency kit. You should always have a blanket or something to keep you and your passengers warm if you get stranded. If you will be venturing away from civilization, pack more items such as food and water to help you survive. Keeping at least half a tank of gas is a good precaution if you get stuck and need to run the car to keep warm and it will help keep your gas lines from freezing up.

Winter in Barnhart Missouri always makes us think of our windshield wiper blades – usually during that first storm when they aren’t working right. That’s why it’s a really good idea to replace your blades in the fall before the winter storms. If you live where there’s a lot of snow and ice, you might want a special winter blade that resists freezing up. And be sure to have enough windshield washer fluid.

The final thing to consider is your tires. Any tire can lose pressure over time – up to one pound every six or eight weeks. For every 10 degrees the temperature drops you lose another pound of pressure. So if it was 80 degrees outside when you checked your tire pressure two months ago and now it’s 40 degrees out, you could be down 5 pounds of pressure. That’s enough to be a real safety issue and it wastes gas too. You may need special winter tires as well. Your tire professional can help you find the right tire design for your expected road conditions.

If you’re getting winter tires, it is always best to put them on all four wheels. If you are only getting two, have them put on the rear – even if you have a front-wheel drive or four-wheel drive vehicle.

This is a very important safety measure recommended by tire manufacturers. Sliding or fish-tailing on ice and snow is a matter of not having enough traction at the rear end. That is why your newest tires should always be on the rear.

Barnhart Tire Repair

Most folks around Barnhart have had a flat tire. You know it’s inconvenient and a pain. Our tires are important. Keeping them in good working order isn’t just a big safety issue – it also has a financial impact. With high gas prices, we’ve all heard about the importance of keeping proper tire pressure to save on gas. In addition, proper inflation promotes even tread wear so your tires last longer.

There’s another danger to under-inflated tires. Low tire pressure puts added stress on the structure of the tire itself, causing it to break down prematurely. Also, under-inflated tires generate more heat which also reduces tire life. So get those slow leaks fixed quickly – don’t just keep airing them up every few days. You want to avoid serious tire damage.

Tires can also be damaged by road hazards in and around Barnhart. Punctures, cuts and impacts on curbs or potholes can also cause damage that could lead to tire failure. Sometimes, it’s something that a visual inspection would reveal. Take the opportunity to check your tires when you’re gassing up. Look for slashes, missing chunks, nails or screws in the tread or just uneven wear. Of course check the air pressure too.

Now tire damage can be on the inside where you can’t see it until it’s removed from the wheel. Such damage could come from a severe impact, driving on a flat or even just low pressure. Some punctures can cause internal damage that are too severe to be repaired. You may see our Kevin’s Car Care professionals take the time to remove your flat from the rim and inspect the inside before repairing it, which means we’re just following good procedure.

Now some tires just can’t be repaired. A puncture may be too large to plug. Also, the puncture could be in a location that’s not safe to repair like in the sidewall or outer portion of the tread. So called run-flat tires should not be repaired because their design is such that internal damage can’t be detected by a visual inspection.

It is also important that repairs should only be done by a qualified tire specialist like the ones we have at Kevin’s Car Care. You can buy self repair kits – save those for emergencies, like when you’re off-roading and need a quick fix so you can hobble back to civilization and get professional help. If you need to use a repair-in-a-can product, remember it’s a temporary measure only and your tire needs to be properly repaired as soon as possible.

Here are some other considerations: Repairing a flat may void your tire manufacturer’s warranty – just something to keep in mind. Also, if you repair a speed rated tire, you should not use it in any motorsports or operate it above legal speed limits. Your tire professional will repair your tire whenever it’s safe to do so and he’ll advise you when it’s better to replace it. So watch those curbs and keep the air – on the inside.
