What Does 295/55R15 Actually Mean?

Let's break it down simply: The 295 means this tire has a tread width of 295 millimeters. The 55 is the aspect ratio, which means the sidewall height is 55% of that width. The "R" stands for Radial construction (the modern standard for safety and durability), and finally, the 15 indicates that this tire perfectly fits a 15-inch wheel.
