Many modern cars have tire pressure meters that will notify you when the tire pressure is low. Without these meters, it is possible that a pressure drop will go unnoticed until your tires are ruined, or worse, blown out.
When tires are properly inflated, they will wear evenly and the tires will last longer. If a tire is used while under-inflated, the sidewalls will take most of the pressure and the tire will wear on the outside. If a tire is over-inflated, it will bulge in the middle and the car will run on the center part of the tire.
If damage occurs on the road, your tires may deflate quickly. A good indication your tires are dangerously low is if the car feels wobbly when cornering. This is because the car is sliding out on the tire’s sidewall. At this point it is very important to replace the tire immediately. Check tire pressure after every other gas fill up.
Be sure to also check the tread depth. Most tires have raised bars inside sections of the tread. Once the tread wears close to these bars, it is time to replace the tires.
It is recommended that all four tires are replaced at once, especially if your car is all-wheel drive. If your car is two-wheel drive, it may be more economical to replace the two most-worn tires. The new tires should be on the drive wheels.
If your tires are developing pits or abnormal wear, your suspension parts may be misaligned. It is important to take your vehicle to an ASE certified technician, who will be able to diagnose the problem and check the safety of your Yorktown tires.
