Roctane XD Adds Dual Kevlar Belts

New 26-inch sizes for 12-inch wheels! Same great durability and performance, now to better fit ATVs.

The all-new Roctane XD-K features Dual Kevlar® belts for added durability. A lightweight synthetic fiber with five times the tensile strength of steel, Kevlar® has a bulletproof reputation that matches its application. With dual Kevlar® belts engineered in a cross-weave pattern running shoulder to shoulder on the new Roctane XD-K tires, STI Tire & Wheel triples the puncture resistance of this nearly impenetrable tire.

With its 8-ply-rated radial carcass, the Roctane XD-K is built to confidently handle today's UTVs, no matter how large, fast and aggressive they are. Available in four different sizes, there is a Roctane XD-K for your machine. All Roctane XD tires use a specially formulated tread compound that extends tire life, while adding grip on the slickest rocks like a dedicated wall-crawler.
