Our goal is to design UTV tires and Utility ATV tires that break new ground, literally and in the innovative sense. From the all-new R4 mudder to Roctane to Sand Drifter and more, we deliver performance to cover a variety of terrain. We understand that durability is as important as traction, and all STI tires use long-lasting designs, whether you need 6-ply up to 10-ply. And we do it all at prices you’ll appreciate. Check out the specifics on each tire page. And check with your favorite retailer for pricing and availability.
