Most tires have sidewalls that are reinforced with steel or nylon bands. The sidewall is the part of the tire between the rim and the tread. It protects the tire from damage and provides support for the weight of the vehicle.
The sidewall is also where information about the tire is printed. This includes the manufacturer, model, size, load rating, speed rating, and other important information.
Sidewall damage can be caused by road debris, potholes, curbs, or other objects. It can also be caused by improper inflation or overloading of the tire. Sidewall damage can lead to a blowout or loss of control of the vehicle.
It is important to inspect your tires regularly for any signs of damage. If you see any cracks, bulges, or cuts in the sidewall, it is time to replace your tire.
