TIRE SIZE CHART

Tire Size Chart Meaning

  • Overall Diameter: measured from the outside edges of the wheel
  • Tread Width: measurement of the tire at its thickest point. The distance between the outer sidewall’s widest point and the inner sidewall’s widest point. This physical width of the tire can change if the tire is mounted on a wheel slightly wider or narrower than the size indicated by the rim width
  • Sidewall height: measured from the wheel rim to the top of the tread, expressed as a percentage of tire width.
  • Rim Diameter: This number represents the distance between the two bead seat areas where the tire is sealed onto the wheel
  • Revs/mile (km) indicates the number of times a tire revolves while it covers the distance of one mile/kilometer
