IMPORTANT!
CHECK FITMENT GUIDE or you WILL get THE WRONG SIZE MOUSSE
Offroad tire sizing is extremely inconsistent between tire models. For example, a Kenda IBEX 110/100-18 takes NM18-285 and a Metzler MC4 110/100-18 takes NM18-325 which is 2 sizes larger than the NITRO for the Kenda tire.
Here are 3 search options to find the NITRO that matches your specific tire.
