What Does 275/50R24 Actually Mean?

Let's break it down simply: The 275 means this tire has a tread width of 275 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 24 indicates that this tire perfectly fits a 24-inch wheel.
