What Does 255/50R21 Actually Mean?
Let's break it down simply: The 255 means this tire has a tread width of 255 millimeters. The 50 is the aspect ratio, which means the sidewall height is 50% of that width. The "R" stands for Radial construction (the modern standard for safety and durability), and finally, the 21 indicates that this tire perfectly fits a 21-inch wheel.
