Tire Maintenance in Bloomington

With the recent focus in the Bloomington area on improving fuel economy, we've been told how important it is to maintain our tire pressure.

Bloomington drivers know that tires wear out, but we want to make them last as long as possible because they're not cheap to replace. In addition to saving gas, properly inflated tires last longer. Underinflated tires will wear out more quickly.

Some people in Bloomington wonder if they should add a few extra pounds of pressure when they fill up their tires. Bad idea. In fact, there are very good reasons not to overinflate your tires. For one, the middle of the tread will wear unevenly because the full tread is not contacting the road properly. That also adversely affects your handling.

Stop by AutoChoice Service Center Inc. to see about tire maintenance for your vehicle.

Every vehicle in the Bloomington area has a sticker on the driver's side door jamb that tells you the vehicle manufacture's recommended tire pressure. This recommendation is an integral part of the vehicle's suspension tuning. A lot of engineering actually goes into the recommended tire pressure, so it's important for drivers to follow it.

What else do Bloomington drivers need to know about tire maintenance? Tire rotation and balancing are very important. Let's start with rotation. Because the front tires handle the brunt of turning forces, the shoulders of the front tires wear more quickly than the rear tires. At AutoChoice Service Center Inc. in Bloomington, we rotate the tires so that they all get to do some duty on the front, and they'll all wear evenly over their live.

For most vehicles, front tires are rotated to the rear and vice versa. Others recommend a cross rotational pattern. Some vehicles use an asymmetrical tire so those tires need to stay on either the right or left side – it'll say which on the tire. Some high performance cars have asymmetrical tires and different sizes on the front and rear. These can't be rotated at all. Your owner's manual will have details for your vehicle or ask your service advisor at AutoChoice Service Center Inc..

How often should people near Bloomington rotate their tires? Your owner's manual will have a recommendation. Your technician at AutoChoice Service Center Inc. in Bloomington can do a visual inspection to let you know if it looks like it should be done. The interval is typically around 5,000 miles/8,000 km.

You know, some people don't think new tires need to be balanced. What they aren't taking into account is the wheel. Between the wheel and the tire – even a new tire – there's enough variation to require balancing.

When you add the valve stem and tire pressure monitoring sensors required on new cars, balancing is definitely important. When a tire's out of balance, it's actually hopping down the road. Bloomington vehicles with tires out of balance will feel the vibration through the steering wheel if a front tire's out of balance and through the seat if it's a rear tire.

Proper wheel balance promotes tire life and increases safety for Bloomington drivers and their passengers. Historically, lead weights have been attached to the wheel to bring it into balance. Lead gives some environmental concern, so steel weights are starting to be substituted. 

The team at AutoChoice Service Center Inc. also wants to remind you that it is important to always use the same size tire on an axle. Different size tires on the front or on the back can lead to some real handling problems. And tire manufacturers recommend that when you get two new tires, they be installed on the rear because that's where you need the most traction to avoid spinning out.

When Are Your Tires Worn Out?

Hey Bloomington area drivers, are your tires worn out? What is the standard for our Indiana streets? How can you tell on your vehicle?

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

Two-thirty-seconds of an inch 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 tread depth on a tire, it can't move surface water out of the way and you start to hydroplane.

In a safety 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 accelerated 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, or 3.2 mm
• 2/32 of an inch, or 1.6 mm

So what happened with the 2/32 inch/1.6 mm tires on the car? Get this – when the car had traveled the distance required to stop with new tires, it was still going 55 mph/89 kph. Stopping distance was nearly doubled to 379 feet/116 meters, 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 mph/89 kph with the worn tires.

Now, with the partially worn tires – at 4/32 of an inch, or 3.2 mm – the car was still going at 45 mph/72 kph at the point where new tires brought the car to a halt. It took nearly 100 feet, or about 30 meters, 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 inch or 3.2 mm? Easy; just insert an American 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 inch, or 1.6 mm, to Abraham Lincoln's head. The quarter is the new recommendation – 4/32 inch, or 3.2 mm.

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".

Transmission Care in Bloomington, Indiana

Do you have any plans around Bloomington, Indiana , for the weekend? Maybe you and some friends are taking the boat up to the lake. Maybe you'll be having a lot of fun water skiing and doing a little fishing.

You got the boat all ready. It's all gassed up. You packed lots of snacks and the cooler's stocked – ready to go.

How about your tow vehicle? It has plenty of gas and you've even vacuumed it out, but is your auto maintenance up to date?

Stop and think. You'll have some heavy traffic on your way out of town. Hilly terrain as you get to the lake. Some dirt roads – and you may have hot weather. And all the time you're going to be towing around a lot of extra weight.

That all adds up a lot of severe strain on your engine, brakes and transmission. Your transmission's going to be working overtime, spending more time in lower gears. The internal transmission temperature is going to be much higher than normal. What's a fun little blast to the lake for you is really severe duty for your transmission.

It's important that you have enough transmission fluid. If you're running low, the transmission will run too hot and won't have the protection it needs to cope with the added stress of towing.

And if it's time for a transmission service, you really should have it done at AutoChoice Service Center Inc. before your trip. Transmission fluid breaks down and gets dirty over time. Whether you have an automatic or manual transmission, you need to have it serviced on schedule to make sure it runs efficiently.

Automatic transmissions contain a maze of passages that the fluid has to pass through to keep them shifting smoothly. If you neglect transmission service, the passages can get clogged up and you start to have problems. Neglect your transmission for too long and it can fail. Believe us – you don't want to pay for a major transmission repair.

You know, most of us in Bloomington, Indiana , do a lot of our driving under severe conditions. Towing or hauling a big load is obvious, but there are lots of other things that constitute severe driving conditions. Things like short trips or driving in very hot or very cold weather. Also, dusty roads, city driving around Bloomington, and basically any driving that's not at highway speeds or under ideal conditions is severe driving. We all need to think about whether or not we need to follow the severe service schedule.

So, consider going in for a full service oil change before you leave for the lake to make sure everything has been looked at. Ask for a trip inspection while you're at it. Your Bloomington, Indiana , service technician at AutoChoice Service Center Inc. can check your belts and hoses and let you know if your brakes are in good shape.

Don't forget the sunscreen. And to thank your AutoChoice Service Center Inc. service technician, how about bringing him back a nice trout?

On Board Diagnostics for Your vehicle

Today we're going to talk about on-board diagnostics and the questions we hear from folks around Bloomington, Indiana , who need answers about diagnostic services. They want to know what diagnostics are, what's involved and what the benefits are. They really want to understand the value of diagnostic scans by a trained technician in Bloomington.

These are valid concerns. If you don't understand something it's really hard to know its value. Let's start with some history.

Since 1996, all cars and light trucks in Bloomington, Indiana , have been required to use a standardized diagnostic system to help repair technicians determine what's wrong with your vehicle. The diagnostic system works with the vehicle's Engine Control Module – the computer that controls many engine functions.

The computer monitors dozens of components and processes. Depending on what the sensors read, the computer will make adjustments to compensate for conditions and minor problems. When there is a condition that it can't adjust for, the computer will turn on the Check Engine light.

It is also called the 'service engine soon' light on some vehicles. The warning light signals you to get into your local service center so that the trouble code can be read and the problem can be fixed. Your service center will have a scan tool and powerful software that will help the technician diagnose the problem.

If you've searched for Check Engine light on the internet, you may have seen that you can buy an inexpensive scanner or go to an auto parts store to have the trouble code read to tell you exactly what's wrong.

That's a common myth. The code itself doesn't tell you what's broken. It starts you looking in the right place. It tells you what engine parameter is out of range – but it won't tell you what's wrong or how to fix it.

Let's say you think your daughter has a fever. You take her temperature and it reads 102 degrees F/38.9 degrees C. You've confirmed a fever, but you don't know what's causing it. Is it a 24 hour flu, an infection, appendicitis or leukemia? A fever is a symptom of all of these medical problems, but it takes a skilled physician's examination and additional diagnostic tests to find out what is actually causing the fever.

An example of a trouble code could be: P0133, which reads 'Bank 1 sensor 1 circuit slow response.' This means that the front oxygen sensor has a slow response time to changes in the air-fuel mix. If that's all you knew about cars, you would think your oxygen sensor was broken and would replace it. Now, it could be the oxygen sensor – but it could also be a bad or contaminated airflow sensor, exhaust leak, electrical problem, an intake manifold leak or any of a number of other things.

You can imagine a lot of oxygen sensors have been replaced because of that code. So the on-board diagnostics point the way to where the trouble lies, but it takes some skill and high-tech equipment to actually pinpoint the problem. The cheap scan tools that a consumer can buy do not have the ability to retrieve some of the operating history that's stored in the engine control computer. That history's very helpful in diagnosing the problem. Service centers like AutoChoice Service Center Inc. invest a lot of money in high-end diagnostic tools to help solve the mystery and get you back on the road as soon as possible without replacing a lot of parts that don't need replacing.

So, on-board diagnostics provide a powerful starting place for a highly-trained, well-equipped technician to get to the bottom of your problem. When your Check Engine light comes on, get it checked at AutoChoice Service Center Inc.. If the light burns steadily – don't panic. Get in to AutoChoice Service Center Inc. soon to have the engine scanned. A flashing Check Engine light means that there is a severe engine problem. Get in as soon as you can – waiting too long can lead to very expensive damage.

And try to not drive at high speed or tow or haul heavy loads with a flashing Check Engine light.

Make an appointment with AutoChoice Service Center Inc. to have your on board diagnostics analyzed.
