How to Identify Car Tire Tread Patterns and Models
1 Answers
Methods for identifying car tire tread patterns and models: Most tire model markings appear as 215/70R15, where 215 indicates the tire section width in millimeters; 70 is the aspect ratio, representing the percentage of the tire sidewall height to the tire section width (70 means 70%); R denotes a radial tire structure; and 15 is the rim diameter in inches. The tire tread is the part of the tire that directly contacts the road surface, supporting the vehicle. The tire not only bears the load and rolls but also generates friction through its tread blocks against the road surface, serving as the source of power for vehicle propulsion, braking, and steering.
