What Does 175/65R14 Actually Mean?

Let's break it down simply: The 175 means this tire has a tread width of 175 millimeters. The 65 is the aspect ratio, which means the sidewall height is 65% of that width. The "R" stands for Radial construction (the modern standard for safety and durability), and finally, the 14 indicates that this tire perfectly fits a 14-inch wheel.
