TireSizeCalc isn't just a tire size calculator. It's also a tire size finder. In addition to the standard calculator features like width, sidewall, and similar measurements, TireSizeCalc will also provide similar sizes for your selected tire.
You can also change the listing criteria to restric the list to the same rim size as well as the size difference in percent.
Great for finding possible winter tire sizes on smaller rims, alternate track/offroad tire sizes as well.
- View details in CM or Inches, as well as KM or Miles.
- View Width, Sidewall, Radius, Diameter, Circumferance and Revs per Mile (km)
- Speed Difference (% and actual speed in kph/mph) with selectable base speed.
- SAVED VEHICLES. Save tire sizes for your vehicles for later reference and comparison.
- FIND SIMILAR SIZES. Will provide you with a list of similar tire sizes. This list can be altered by changing the difference threshold or by selecting if you'd like to use the same rim size.
