The calculator results should be verified with the tyre manufacturer or the tyre specialist. This is for reference purpose only.

When you find the tyre sizes(i.e., tyre width and series combinations) that fit your rims use our Tire Size Calculator – Tire Dimensions, to compare them with your OE Tyre size to ensure that the selected tyres circumferences or diameters doesn't deviate too much from the OE Tyre circumference or diameter. This is important for many reasons.

This calculator complements our Tyre width for a rim width chart and should be used along with our Rim width for tyre width calculator, which complements prior mentioned calc and chart(tyre4rim). After you choose a tyre size here, do one more check in the Rim width for tyre width calculator, for the selected tyre size, to double check if the selected tyre size has your existing rim in the Recommended rim width range.
