Put these on a RMZ450. Tire hooks up great and shows no sign of wear after 3 hours. Not sure about the longevity but so far so good. Where I ride is a mix of terrains but alot of sandy trails and loose dirt. Real happy so far. Caught mine on sale for $80/set. This tire looks an awful lot like a "32" . Was unsure of when purchased but will probably reshoe with same tires. Installation was smooth and easy just soaped up bead and used 3 spoons.
