1 Answers
It indicates a tire with a cross-section width of 185mm, an aspect ratio of 60, a radial construction, and a rim diameter of 15 inches. Detailed information about the specifications is as follows: 1. 185mm represents the cross-section width of the tire; 60 stands for the aspect ratio, which is the percentage of the tire's cross-section height divided by its width. A higher value means a thicker tire, resulting in lower maneuverability but increased comfort; R denotes the tire type, which is radial, and 15 indicates a rim diameter of 15 inches. 2. H represents the tire's speed rating, which indicates the maximum speed the tire can sustain under specified conditions with a specified load. The maximum speed for H-rated tires under specified load is 210 km/h.
