Vehicle movement is dependent on combustion, engaging in the right gear and making contact with the road. This contact is made with the tire. The rubber helps reduce the friction that is encountered when the car is in motion. Part of ensuring that a car runs correctly is ensuring that all four tires are in proper working order. These are the indications that the tire is too worn to ride on.
Excessive tread wear can be measured by looking at how deep the treads run. The depth is usually compared to a coin to determine if there is enough left to maintain a grip on the road. Tires with smooth treads or a very low depth are no longer viable for vehicle operation. The tread provides the gripping power needed to hug the road. Once this is lost, spinning or burnout may occur.
Most tires are relatively smooth to the touch. The surface is designed to have no bumps or abrasions. A rough surface or unexplained bumps in the surface of the tire can indicate an issue. While this can be caused by rubbing up against a curb, a defect in the material or abnormal changes in air pressure can cause this issue. A visual inspection should be done on occasion to identify if the tire is in trouble.
The inability to maintain proper air pressure can also cause trouble. Tires are designed to keep most of the air inside. While changes in temperature and altitude can have an effect on the tire pressure, a slow leak is an issue. Flat tires lose their ability to reduce the frictional force occurring. This cause the operation of the car to become highly unstable and unpredictable. Aside from the loss of control, a flat can also cause excessive damage to the tire.
Continuous contact with the road is maintained with the tire. However, damages can result in issues with movement. Because damage to the tire can make it hazardous, repair or replacement needs to be done as soon as the issue is detected.
