What Does the Tire Specification of a Car Mean?
1 Answers
The tire specification of a car represents the tire's tread width, aspect ratio, tire type, rim size, load index, and speed rating. Taking 235/45R18 98W as an example, 235 refers to the tire's tread width; 45 refers to the tire's aspect ratio; R indicates that the tire is a radial tire; 18 refers to the rim size; 98 refers to the tire's load index; and W refers to the tire's speed rating. Car tires are one of the important components of a vehicle, directly in contact with the road surface, working together with the car's suspension to cushion the impact during driving, ensuring good ride comfort and smooth driving.
