Wide cupped knobs down the middle provide excellent braking in any conditions. DC - Dual Compound tread provides a lower rolling resistance center paired with extra grip for the corners. EXO equipped models feature Maxxis' EXO sidewall protection which help prevent puncture from sidewall abrasions. TR - Tubeless Ready - sealant required. WT - Wide Track casing optimized for rims over 35mm internal width.
