Urbana drivers know that underinflated tires wear out more quickly. Underinflation is also a major cause of tire failure for Illinois auto owners. More flats, blow outs, skids and longer stopping distances are all results of underinflated tires.

It's hard for many Urbana drivers to tell when a radial tire is underinflated. If your owner’s manual 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 U.S. federal law required vehicle manufacturer’s to include a Tire Pressure Monitoring System - or TPMS system - in all vehicles. Many Canadian vehicles have them as well.  The system is a dashboard mounted warning light that goes off if one or more of the tires falls 25% below its pressure recommendations.

Obviously, all of this doesn't come free for Urbana car owners. 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.

Illinois 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.

PDR service advisors 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 flat repairs, tire changes, and rotations going up, please keep in mind that it's because of government mandated safety equipment. Your Urbana service center just wants to keep you safely on the road - and it's committed to do so at a fair price. Remember, this change will help you avoid the most common vehicle failure, and possibly a catastrophic accident.

Welcome to the PDR automotive blog. Today, let's talk about the effect of tire wear.

Let's focus on stopping in wet Urbana conditions. In order for a tire to have good contact with the road, it has to move the water out of the way. If it can't move the water, the tire will actually ride on top of a thin film of water.

That's called hydroplaning. If it's really bad, Urbana drivers can actually spin out of control - endangering themselves and the other drivers around them. At best, you won't stop as fast.

So how does a tire move water? It has channels for water to flow through. Look at your vehicle tire and you'll see channels: channels that run around the tire and channels that flow across the tire. They're designed to direct water away from the tire so it can contact the road better.

And the deeper the channel, the more water it can move. A brand new PDR tire has very deep channels and can easily move a lot of water. As the tire wears down, the channels become shallower and can move less water. When it wears down enough, it can seriously affect your ability to stop your vehicle on wet Urbana roads.

So that's why it's so important for Urbana drivers to replace their vehicle tires when they get worn. Consumer Reports and other advocate groups call for a standard of 3/32 of an inch and they have the studies to prove it.

At PDR, we want our customers to know that the deeper recommended tread depth makes a big difference. Stopping distances are cut dramatically on wet Urbana streets. A safe stop from Illinois speeds with 4/32 of an inch of tread would result in a crash with worn out tires.

There's an easy way to tell when a tire's worn to 4/32 of an inch.

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 vehicle tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.

Many Urbana residents have heard of this technique using a penny and Abe Lincoln's head - the old method. That measure gives you 2/32 of an inch – half the suggested amount. Of course, vehicle tires are a major purchase. Most of us in Urbana want to get as many miles out of them as we can. But there's a real safety trade-off. It's your choice.

When Urbana drivers need to replace tires, they need to know how many they should get and on which axle they should be placed. Replacing a damaged tire may leave you with three others with significant wear, which could affect your traction control, stability control and anti-lock brake systems.

If you can’t afford to replace all four tires at once, you should at least replace two on the same axle. New tires should always be put on the rear axle for stability in slippery conditions. Your friendly and professional PDR tire professional can help you know when your worn tires should be replaced, if you can have a damaged tire repaired as well as selecting the right tires for your needs.

Urbana drivers want their tires to last as long as possible. Two ways to extend tire life are wheel balancing and tire rotation.

When wheels are out of balance, they wobble and vibrate. That makes the tires wear in a cupping pattern. If a front wheel is out of balance you'll feel it in the steering wheel. If it's a rear wheel you'll feel it through your seat. To fix this, your technician at PDR puts weights on your wheels to balance them out.

That brings us to tire rotation. The front tires on a vehicle wear out faster than the rear tires. As they push through turns, the shoulders of the front tires wear down. So rotating front and rear tires allows them to all wear at about the same rate over the life of the tire.

Proper tire inflation will also help Urbana folks' tires last longer. Underinflated tires wear more on the shoulder and may even overheat. This could cause tire damage or a blow out. Overinflated tires wear too fast in the middle.

Four-wheel-drive trucks and SUV's tend to wear their tires more unevenly so rotation is even more important with them. Give PDR a call to get our recommendation for your vehicle.

See your owner's manual or ask your service advisor at PDR for your recommended tire rotation schedule. It's usually every 5,000 to 8,000 miles, or 8,000 to 13,000 km.

Tires are among the most important safety components on your vehicle. Take care of them and they'll take care of you.

Today's tires and wheels offer a lot of options for every Urbana driver's style, habits and driving conditions.

Tires are designed for high-performance in winter or summer and even come in a long-wearing variety for all Illinois seasons.

Urbana off-roaders should be excited about the options available to them as well. The tread on off-road tires is designed to handle the wear from bumps and rocks. The tires' high profile protects rims from damage.

But what if you own an SUV but aren't interested in off-roading around Illinois? You can change out those high-profile beasts for a lower, wider look if it suits your style.

PDR tire professionals can offer great auto advice on how to choose tires that match your needs and style.

If you just need to purchase new tires, a tire professional at PDR can also help you select the tires that are best for your driving needs and habits. The right tires will protect you and your vehicle on the road.

So personalize your vehicle, but don't forget that good car care will keep that sassy ride on the road in Urbana a lot longer.

Why are wheel bearings for Urbana vehicles important? It's simple: your wheel bearings keep the wheels on your vehicle. In today's PDR post, we'll discuss more about wheel bearings and how you can make sure they can do their very job while you drive around Urbana, Illinois.

Wheel bearings are pretty simple parts. They're made of high quality steel and are engineered to last 100,000 miles (160,000)  or more if properly cared for. The bearings do two jobs: First, they allow the wheel to freely rotate with as little friction as possible. Second, they support the weight of the vehicle. For example, if your car weighs 3,600 pounds (1600 kilogram), each wheel has to support approximately 900 pounds (400 kilograms). That's a lot of heavy lifting over those long distances.

Even though wheel bearings are pretty straightforward, they need to be in near perfect condition to do their job for Urbana vehicles. The bearings are packed with heavy grease to lubricate and protect them. A seal keeps the grease in and water and dirt out. It's when the seal starts to leak that problems begin. The grease can become contaminated, causing the wheel bearings to overheat and ultimately fail.

The first sign that your wheel bearings are in trouble is an unusual noise coming from a wheel. It could be a chirping, growling, rumbling or a cyclic sound. The noise could get louder or even disappear at certain speeds. Your technician at PDR can inspect for bearing wear by lifting the vehicle and checking for play in the wheel.

Now some wheel bearing assemblies are factory sealed. That means that they cannot be serviced – they can only be replaced. Those that aren't sealed can be serviced on schedule at PDR. The bearings are removed, cleaned and inspected. If the bearings are still good, they're re-installed – if not, they're replaced. They are then packed in grease and a new seal is installed.

If your vehicle has a factory sealed wheel bearing assembly, the entire assembly needs to be replaced when trouble arises. Unfortunately, the parts are pretty costly – but they usually last about 150,000 miles (240,000 kilometers) as long as the seals hold up.

Now, even a good seal cannot keep out water that's exerting pressure on the seal. So if you've driven through hub-deep water, your bearings should be cleaned and repacked if they're serviceable. If you have factory sealed bearings, you just need to watch for signs of premature failure. If your wheel bearings can be serviced, your manufacturer's owner's manual will recommend an interval, usually around 30,000 miles (50,000 kilometers).

If you have any sort of trailer, don't forget its wheel bearings. They probably need to be serviced even more frequently. This is especially true for boat trailers that are used to launch the boat by backing it into the water. These should be serviced every year, usually at the end of the season so that the bearings don't have the opportunity to rust all winter.

So what happens to Urbana vehicles if wheel bearings fail? Well, the wheel can literally fall off the vehicle. I don't need to tell you how that could be. So check with your service advisor at PDR and see if your vehicle's wheel bearings can be serviced and when it's recommended. Listen for warning signs. If you've been fording streams or puddle surfing after rainstorms, be especially vigilant.

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 Urbana 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 Urbana 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 Urbana 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 vehicle can be safe with a lower number, but you'll need a higher rating if you routinely haul heavy loads around Urbana. The next letter is the speed rating. Not all tires sold in Urbana 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 Urbana area 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 are 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 manufacturers product line - you can't compare with others. And it's important 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 Illinois 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 buildup in government tests. A, B and C - from best to acceptable.

It's safe for Urbana drivers to go with the vehicle manufacturers 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 friendly and knowledgeable PDR tire professional.

Tires do a lot of work for Urbana drivers. They transfer engine power and braking forces to the road; they handle steering control; and they cushion all those bumps and jolts while driving around Urbana. They also support the entire weight of the vehicle, including you and your passengers. With such important work to do, you want your tires to do their job well. And since replacing tires is fairly pricey, you want them to last as long as possible.

There are three keys to long, even tire wear for Urbana driving:

• Proper tire inflation
• Proper wheel alignment
• Regular tire rotation and balancing

The front tires on a car take the brunt of the steering forces. As they push through turns, the shoulders of the front tires wear down more quickly than the rear tires. Rotating front and rear tires allows them to all wear at about the same rate. That's especially true of front-wheel-drive vehicles whose front tires steer and put the power to the road.

SUVs and pick-ups, especially four-wheel-drives, also tend to wear their tires more unevenly than cars because of their suspension and drivetrain set-up. Your owner's manual will likely contain a schedule for tire rotation. It's usually every 5,000 miles/8,000 km or so.

Also, there are different rotation patterns for different vehicles. PDR will know which is right for your vehicle. That brings us to wheel balancing. When wheels are balanced, they spin on the axle evenly. When they are out of balance, they wobble a bit. That makes the tires wear unevenly and may transmit a vibration to the car. Your friendly and knowledgeable PDR service advisor puts weights on your wheels to balance them out so that they turn true and smooth.

Tires are a big investment for Urbana drivers. They're designed for keeping you safely on the road in Urbana. The cost for regular rotation and balancing is more than made up in extended tire life. And, can you really put a price on your safety and that of your passengers?

Shopping for tires in Urbana can be bewildering because there are many choices. Let's simplify. There are four main classifications of tires, each designed for different purposes.

First off, there are summer tires. Those who buy summer tires in Urbana are looking for maximum summertime performance. The rubber is a little softer to help stick to the road on fast corners on Illinois roads. The tread has wide blocks at the shoulder to stiffen the tire in turns. The tread design can handle rain but really isn't set up for snow and ice.

Next comes winter tires. Urbana people buy winter tires because they still like performance driving when it's cold and slippery on Illinois roads, so they need a tread design that'll really bite into ice and snow. The rubber compound is formulated to stay pliable when temperatures drop below 45 degrees F/7 degrees C so they get great traction even on dry roads. On the other end of the winter tire spectrum are tires designed to handle well in severe ice and snow conditions.

The third category is all-season tires. Most new cars in Urbana showrooms come with all-season tires. This is a tire that is designed to be used all year round. The tread design and rubber compound is a compromise that won't give you the extreme capabilities of summer or winter tires; but if you're driving and weather conditions aren't at the extreme ends of the range, all-season tires might suit you just fine.

The last category is what you might have on your SUV or pickup. All-terrain or off-road tires are designed for both highway and off-road use – a tire that gets good traction in the dirt and on off-road obstacles, but still performs well on paved Urbana roads.

Choosing the right tire is important for Urbana car owners. Talk with your PDR tire professional about your driving requirements and receive valuable guidance on tires that will meet your needs.

Tires are an expensive purchase, so knowing when tires should be replaced is important for Urbana drivers. Tires will just wear out with normal use. The depth of the tread on your tire determines how well it will stop, start and steer – especially in wet conditions. 4/32th of an inch (3.2 mm) of tire tread is considered a safe amount of tread.

Uneven tread wear can be a symptom of other problems, and simply replacing your tires will not prevent the same uneven wear from happening to the new tires. At PDR in Urbana, we can inspect your tires for excessive or uneven wear. Unusual wear may lead to further inspection of steering, suspension or alignment problems. We can help with necessary repairs and with getting you the right tires for your needs.
