Tire Size Conversion Chart - Inches to Metric - by Wheel/Rim Diameter

Tire Size Conversion Chart - Inches to Metric - by Wheel/Rim Diameter displays the inch tire size designations and for each inch tire designation shows the equivalent - exact calculated metric tire size.

The tire conversion chart along with our Tire Size Converter may prove useful when one wants to replace an inch tire with a metric tire or the other way around, both can help you find a compatible tire size in the other measurement system.

Inch tire sizes are grouped by a wheel/rim diameter - there is one chart for each rim diameter, which you can select by clicking the appropriate link.

The chart data can be filtered and sorted by each column with a click on the appropriate table column heading.

More information on how to use the charts on this page: How to use the charts.
