255/55R17 Tires

Without tires you cannot drive your vehicle. That much is known. But what is the first thing you need to consider when buying new tires? The simple answer is the tire size. Every tire has a tire size, which consists of numbers and letters – all telling us important information of the tire width, sidewall, and rim diameter. All of these determine what type of characteristics the tires can offer.

255/55R17 Tire Size Explanation

  • 255 - This number represents the tire’s width in millimeters, measured from one shoulder to the other. In this case, the tire’s width is 255 mm (10.04 inches).
  • 55 - The aspect ratio is expressed as a percentage of the tire’s height to its width. A 55-aspect ratio means that the tire’s height is 55% of its width (in this case it is 140.25 mm / 5.52 inches).
  • R - This indicates that the tire was manufactured with a radial construction, which is the most common tire construction type used today.
  • 17 - This last number denotes the diameter of the wheel in inches. This tire was manufactured to be mounted on 17-inch (431.8 mm) wheels.
