Frequently Asked Questions

What does the 285/55R20 tire size mean?

The 285/55R20 tire size refers to the tire’s width, aspect ratio, and rim diameter. The “285” is the width of the tire in millimeters, the “55” is the aspect ratio (the tire’s height as a percentage of its width), and the “R20” indicates the tire’s construction type (radial) and the rim diameter in inches.

How wide are 285/55R20 tires in inches?

Since the tire width is 285 millimeters, we can convert it to inches by dividing by 25.4 (since there are 25.4 millimeters in an inch). This gives us approximately 11.2 inches. So, 285/55R20 tires are approximately 11.2 inches wide.

What is the diameter of 285/55R20 tires?

The diameter of the tire is determined by the rim diameter, which is 20 inches. The overall diameter of the tire will be slightly larger due to the tire’s sidewall height. However, for most practical purposes, the rim diameter is a good estimate of the tire’s diameter.

How tall are 285/55R20 tires?

The aspect ratio of 55 means that the tire’s height is 55% of its width. Since the width is approximately 11.2 inches, the height would be 6.16 inches (11.2 x 0.55). So, 285/55R20 tires are approximately 6.16 inches tall.

Can I put 285/55R20 tires on a different rim size?

While it’s technically possible to put 285/55R20 tires on a different rim size, it’s not recommended. The tire’s dimensions are specifically designed to work with a 20-inch rim, and using a different rim size could affect the tire’s performance, handling, and safety. It’s best to stick with the recommended rim size for the best results.
