What Does 195/60R17 Actually Mean?

Let's break it down simply: The 195 means this tire has a tread width of 195 millimeters. The 60 is the aspect ratio, which means the sidewall height is 60% of that width. The "R" stands for Radial construction (the modern standard for safety and durability), and finally, the 17 indicates that this tire perfectly fits a 17-inch wheel.
