Taking proper care of the tires on your car not only saves money, it could save your life. Here's some advice from the Rubber Manufacturers' Association:
* Inflate tires properly. Under-inflation makes it more likely that you will lose control or skid. Yet most cars have underinflated tires. Tire pressure can be low without tires looking flat.
* Check the label on the door, in the glove compartment, or on the fuel door for air pressure guides. Some makers recommend different pressures for front and rear tires, especially for SUVs.
* It's best to test pressure when tires are cold. Check every couple of weeks and before leaving on a trip.
* Avoid fast starts and stops, don't bump the curb when parking, and don't overload the car.
