The Tire Size Converter performs tire size conversion from the inch tire size (English/Standard/Imperial measuring system) to the metric tire size and the other way around. Besides the exact tire size conversion from one system of measurement to another, calculator displays adequate actual/real tires with the dimensions which are closest to the calculated tire size, if such exist. The Converter also shows, for the real tire, its dimensions: tire diameter, tire width, sidewall height and the difference between that tire and the original tire.

Disclaimer:
The Tire size converter results should be verified with the tyre manufacturer. This is for informative purposes only. The tyresizecalculator.com is not responsible for any miscalculations of this calculator or any errors that may arise with its usage.

When converting the tire dimensions from one system of measurement to another (Metric to Standard/Imperial/English or the other way around) pay special attention to the following: the tire construction (Radial or Bias-ply), the wheel/rim width and offset, the tire speed rating, the tire load capacity, the maximum inflation pressure.

The commercial tires(brands) quoted in the Actual-Real metric/inch tire size section are just an example - not a recommendation for purchase. These are just some of the available tires on the market with the appropriate/adequate tire dimensions.
