How to Identify the Corresponding Tire Model for Steel Wheels
1 Answers
Steel wheels' corresponding tire models can be analyzed through numbers and letters. Here are the detailed explanations: 1. Number explanations: "255" refers to the tire's section width, which is the distance between the two sidewalls, measured in millimeters. "18" indicates the rim diameter. "109" represents the load index, where different load indices correspond to different maximum load capacities, usually measured in pounds or kilograms. 2. Letter explanations: "R" refers to the tire's construction, indicating that this tire has a radial structure. "Y" denotes the speed rating, where different English letters represent different speed ratings.
