Dual Steel Belts, 10-Ply Radial

Built to chew up and spit out rocks, roots and mud, the all-new STI Roctane X2 will conquer trails with long-lasting performance. The Roctane X2 uses its large footprint and multi-edge tread to deliver sure-footed traction.

Designed using a two-stage radial carcass, this 10-ply rated tire features dual-steel belts, stepped shoulder tread, and a deep rim guard. The leading-edge design produces a tire that’s more uniform and delivers superior handling and comfort in choppy and loose terrain. Whether you ride in the woody hills out east or the rocky trails out west or anywhere in between, the STI Roctane X2 supplies the durability and the performance you need.

The all-new STI Roctane X2 tires are available now in sizes from 27-inch up to 32-inch for 14-inch wheels.
