The sidewall is constructed of multiple layers of rubber, fabric, and steel cords, which give the tire its strength, flexibility, and resistance to wear and damage. On the exterior of the sidewall, you can find important information about the tire, including:

  1. Tire size: A series of numbers and letters indicating the tire’s width, aspect ratio, and diameter.
  2. Load carrying capacity and speed rating: Specifies the maximum load the tire can carry at a specific speed.
  3. Tire type: Indicates if the tire is designed for use on passenger cars, light trucks, or other types of vehicles.
  4. Construction type: Describes the internal structure of the tire, such as radial or bias-ply construction.
  5. Manufacturer details: The brand name and model of the tire.
  6. DOT code: A code that provides information about the tire’s manufacturing date and location.

A tire’s sidewall plays a crucial role in its overall performance and safety. Any damage to the sidewall, such as cuts, punctures, or bulges, can compromise the tire’s structural integrity and increase the risk of a blowout or failure while driving. If you suspect sidewall damage, it is important to have the tire inspected by a professional and replaced if necessary.
