Tire Size Conversion Chart - Metric to Inches - by OD
Tire Size Conversion Chart - Metric to Inches - by Overall Diameter shows the metric tire sizes and for every metric tire size displays equvalent - the exact calculated inch tire size.
The tire size conversion chart together with our Tire Size Converter can be useful when one wants to replace a metric tire with an inch tire, they both might help you find an equivalent inch tire size.
Metric tire sizes are grouped by an overall tire diameter - one chart for each overall diameter, which you can select by click on 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.
Please choose the overall diameter:

Note: The equivalent inch tire sizes displayed in the chart are not the real tire sizes which you can buy in a store, these are only hints. Our Metric/Inch Tire Size Converter can give you an additional and more precise information because besides the exact calculated inch tire dimension, it also displays real tire dimensions which you can find in a store, if such exist.
