STI delivers high-performance ATV, UTV tires and wheels and off-road motorcycle tires. STI offers more application and fit options than any competitor. They research and develop a wide-range of tires for dirt, sand and any terrain you can throw at them. Their wheels are precision machined and accentuate your ride to provide style and function. As riders and racers, STI knows their way around the track and trails and the development of their tires and wheels is a direct result of that experience to give you more confidence and control on any terrain. To "cap" it off, STI also offers a range of center wheel caps whether you lost a cap or just want to freshen up the look of your ride.
