Maxxis - Maxxcross MX-SI Tires

Born from the dirt and tuned by none other than 7X Supercross legend Jeremy McGrath, the Maxxis Maxxcross MX-SI is built to rip through soft-to-intermediate terrain with authority. This isn’t just another motocross tire—it’s a race-bred weapon designed to turn throttle twist into pure traction and confidence lap after lap.

The redesigned tread pattern and updated compounding dig in hard, giving you insane grip when you crack the throttle out of corners and put your bike’s power to the ground in softer terrain. Up front, the new tread design and carcass construction provide lean angle confidence, predictability, and stability when you’re carving ruts or attacking jumps. The result? A tire that stays locked in when the track gets chewed up and rough, letting you push harder, longer, and faster.

With superior consistency and traction dialed for real-world motocross conditions, the MX-SI gives you the edge to perform whether you’re battling through loamy berms, hammering whoops, or slicing through mid-pack chaos. It’s the next evolution in the Maxxis MX line—and it’s built for riders who demand more.
