Reading Tire Information

Tires sold in the US, have valuable information printed on the sidewalls. A typical tire marking might be 225/55 R 17. Reading these markings yields the below-listed information.

  • R indicates that the tire is a radial tire with a distinctive construction.
  • 225 is the tire tread width listed in millimeters- 225 mm.
  • 17 represents the tire diameter and the size of the wheel required to hold it in place on the vehicle.
  • 55 is the aspect ratio, a figure that shows the height of the sidewall relative to the width of the tread.
