Breaking Down Tire Number Meaning

To understand what tire numbers mean, let’s break down a typical tire code, such as “225/65R17 102H.” Each section of the code represents a specific feature of the tire:

1. 225: This is the tire’s width in millimeters, measuring from sidewall to sidewall. The wider the number, the wider the tire.
2. 65: This represents the aspect ratio, or the height of the sidewall as a percentage of the tire’s width. In this case, the sidewall height is 65% of the tire’s width.
3. R: The “R” indicates the tire’s construction type, with “R” standing for radial, which is the most common type of tire construction today.
4. 17: This is the diameter of the wheel in inches, showing the size of the wheel the tire will fit.
5. 102: This number refers to the tire’s load index, representing the maximum weight the tire can carry.
6. H: The letter at the end indicates the tire’s speed rating, showing the maximum speed the tire can handle safely.
