This calculator works on any wheel providing you have removed the tire. Simply measure the interior width and depth and the complete diameter of the wheel, hub or rim. The Air Free Tire Selector is easy to use and we have 'loosened' up the algorithm so that it may return as many matches as possible. This means that you need to be careful when looking over the results and determine if any tires will work for you. 

Please double check as the calculator puts you in the ballpark for fit but is not exact. If your measurements do not return any results, please send them to us so that we may look them over and offer other suggestions.

All of our tires have certain 'stretch' and 'compression' ratios which we enter into into the tire selector.  If your rim is too wide for any of our tires or it is too shallow or the diameter is off, then the selector will tell you. If any of our tires are found to fit the dimensions you entered, then the links to the tires are displayed. If we don't have something to fit, please send us your measurements by clicking the "send report" link on the next page and we can look it over.

Please try to be accurate when you measure your rim and round off numbers if you like but only enter numbers into the input boxes and not fractions.

Please don't enter "mm" or fractions as the selector won't understand that. Just use numbers.

Once you enter your dimensions into the selector, all of our tires that can fit are displayed. Please follow any suggestions or instructions given and please let us know the make and model of your rims in the unlikely event that we don't have a tire to fit.
