Roctane XR - Trail TamersSTI revolutionizes the Roctane with the new XR family of tires, led by a 35-inch trail-tamer tire made for 18-inch wheels (like the all-new STI HD9 18-inch). The XR line also includes four more sizes, from 28- to 33-inch tires. With their 9.5-inch wide sizing and new 8-ply rated radial carcass, the Roctane XRs deliver lightweight, all-terrain performance at a great price.
With the changes they engineered, STI was able to deliver tires that are 20- to 30-percent lighter than similar-sized Roctane XD tires, and are available at retail prices up to 30-percent lower. And performance was not sacrificed.
Starting with the original Roctane XD, STI re-imagined a lighter, all-terrain, trail-oriented tire to make the new Roctane XR. With superior traction and precise handling, the Roctane XR tires set a higher standard for all-terrain traction, with handling that's on the money - for less money.
- 9.5 inch profile.
- 8-ply rated radial, durable, traction monster.
- Designed for premium handling and light weight.
- Multi-angle tread blocks with dimples and ample biting edges.
