The SM is an exclusive sand and mud tire that combines a mud-repelling, silica-based rubber compound with a computer-enhanced tread design. In addition to its specially formulated compound, the SM tire also incorporates anti-flex knob bridges on the shoulder, increasing traction and stability. The Maxxcross SM has been used by professional riders like 5-time GNCC Champion Scott Summers and Rodney Smith and 5-time Hollister National Hare Scrambles winner Brian Garrahan.
