Our tire size conversion calculator will help you convert metric tire size to inches to better understand your tire's dimensions.
Tire specifications may vary slightly from the calculations. Specs are based on a properly inflated tire mounted on the measured rim size and NOT installed on the vehicle. Measuring tire specs under the weight of the vehicle will produce slightly different results due to the added load.
