275/45R21 Tires

Getting the correct tire size is crucial when buying new tires. While tire size does not dictate the specific characteristics each tire has, it is something that cannot be neglected when searching for your next tire set. Each tire size consists of numbers and letters that have specific meanings. The different components of the tire size together determine on which vehicles and in what type of applications these tires can be used. Learn more about what each section of the tire size means.

275/45R21 Tire Size Explanation

  • 275 - This number represents the tire’s width in millimeters, measured from one shoulder to the other. In this case, the tire’s width is 275 mm (10.83 inches).
  • 45 - The aspect ratio is expressed as a percentage of the tire’s height to its width. A 45-aspect ratio means that the tire’s height is 45% of its width (in this case it is 123.75 mm / 4.87 inches).
  • R - This indicates that the tire was manufactured with a radial construction, which is the most common tire construction type used today.
  • 21 - This last number denotes the diameter of the wheel in inches. This tire was manufactured to be mounted on 21-inch (533.4 mm) wheels.
