22550r17 tire means the tire width is 225mm, the aspect ratio is 50%, the tire type is radial, and the rim diameter is 17 inches. Tires are generally composed of three parts: the outer tire, the inner tube, and the tread belt. The inner layer of the tire has a rubber layer with excellent airtightness, gradually moving towards lightweight development. The outer tire mainly consists of the carcass, tread, sidewall, and bead. Car tires are one of the important components of a vehicle, directly in contact with the road surface. Together with the car suspension, they help to cushion the impact during driving, ensuring good ride comfort and smoothness, as well as maintaining excellent adhesion between the wheels and the road surface, thereby improving the car's traction, braking, and off-road capability.
