Tire measurements typically consist of three numbers, such as 205/55R16. The first number (205) indicates the tire's width in millimeters, the second number (55) represents the aspect ratio, which is the height of the sidewall as a percentage of the width. The "R" denotes that the tire is of radial construction, and the last number (16) indicates the diameter of the wheel in inches that the tire is designed to fit. Together, these measurements help ensure proper fit and performance for the vehicle.
