What Does 275/70R18 Mean?

The term “275/70R18” refers to the size and specifications of a tire. Here’s a breakdown of what each part of the designation means:

275: This number represents the width of the tire in millimeters. In this case, the tire is 275 millimeters wide from sidewall to sidewall.
70: This number indicates the aspect ratio, which is the ratio of the tire’s sidewall height to its width. In this example, the aspect ratio is 70, meaning the sidewall height is 70% of the tire’s width.
R: This letter stands for “radial,” which is the most common type of tire construction. Radial tires have ply cords that run perpendicular to the direction of travel.
18: This number represents the diameter of the wheel, in inches, on which the tire is designed to fit.

So, in summary, a tire with the designation 275/70R18 is a radial tire that is 275 millimeters wide, with a sidewall height that is 70% of the width, and it is designed to fit a 18-inch wheel.

What Is 275/70R18 In Inches?

The tire size 275/70R18 can be expressed in inches as approximately 10.8 inches wide, 7.6 inches tall in sidewall, and designed to fit a 18-inch wheel rim.

This equates to a tire height of 33.2 inches. The 275/70R18 also has a circumference of 104.2 inches and It completes 608.3 revolutions per mile.
