How to Read Tire Size Specifications?
1 Answers
Tire size specifications can be viewed as follows: 1. International standard tire sizes are measured in millimeters, with each identifier representing tire width, aspect ratio, tire type, rim diameter, load index, and speed rating. 2. Example: Tire size 205/55R16-91W. 1. 205 indicates the tire width is 205mm. 2. 55 means the tire's section height to width ratio is 55%, which is the aspect ratio. 3. "R" stands for RADIAL, indicating it's a radial tire. 4. 16 shows the rim diameter is 16 inches. 5. 91 represents the load index. 6. W indicates the tire's permissible speed rating.
