The Michelin MS3 rear tyre is ideally suitable for soft to medium hard terrain conditions. The M shape block Patten has scoops that can easily penetrate soft surfaces. These blocks are reinforced to resist wear and knob flex. The wide spacing helps clean the built up mud. These tyres offer fantastic straight line drive and are great off the start. You should run about 15 psi in the rear. They last quiet well when used in the right conditions. Not DOT tyre. Not to hard to fit.
