Flat tires can be caused by a variety of factors including rough roads, tire punctures, a damaged valve system, worn out tires and even hot weather. When a flat tire occurs, it is important to get it repaired as soon as possible. Driving on a flat tire can be dangerous, cause irrevocable damage to the tire and result in rim damage. Signs of tire damage can include excessive or too little air pressure, unequal tire wear, wheel alignment/tire balancing issues, and suspension problems. The sooner you bring in a lightly to moderately damaged tire for repair, the more likely it can be repaired and the less it will cost.
