Tires / Tire pressure
Problems with tires
Underinflation can cause tires to wear more on the outside than the inside. It also causes reduced fuel efficiency and increased heat buildup in the tires. It is important to check the tire pressure with a gauge at least once a month.
Overinflation causes tires to wear more in the center of the tread. The tire pressure should never exceed the maximum that is listed on the side of the tire. Car manufacturers often suggest a lower pressure than the maximum because the tires will give a softer ride. But running the tires at a higher pressure will improve mileage.
Misalignment of the wheels causes either the inside or the outside to wear unevenly, or to have a rough, slightly torn appearance.
Feel vibration at cruising speed?
Have your tires balanced. Uneven tire wear indicates alignment problem. Improper alignment causes increased tire and suspension components wear and poor handling. If a car pulls aside, wanders or feels unstable on the road, have the alignment checked. Properly done alignment will make your car rides a lot more enjoyable.
Check the tire pressure regularly
At least once a month. If you don’t have the tire pressure gauge, it’s worth to buy a good one. You can find the recommended tire pressure in the owner’s manual or on the tire pressure placard, which might be located on the driver’s door jamb, inside the gas tank lid or inside the glove box.
Checking tire pressure
Measure tire pressure when the tires are still cold.
Tire pressure gauge
Pump or deflate to the recommended pressure. The maximum pressure listed on tires is NOT the proper pressure!
There is a safe limit of the tread wear. If the tire is worn below this limit, it’s unsafe to drive. Your owner’s manual will have the directions on how to measure tire wear, or your mechanic can check your tires for you.
Front and rear tires wear at different rates and have different wear pattern. On a typical front-wheel drive vehicle, for instance, the front tires would wear out a lot faster than the rear ones if not rotated regularly. By rotating your tires regularly, you are making sure that your tires wear more evenly and last longer. Some manufacturers recommend to rotate tires at every oil change, others may recommend to do it at different intervals. Tire rotation pattern is also different for different tires. It’s best to check your owner’s manual or call your local dealer for exact recommendations for your tires.
