Collection: Tubes

Money-Saving Performance & Toughness

STI Motorcycle Tubes are strong, stronger, strongest. At 2mm thick, the “Heavy Duty” model is 50 percent thicker than most standard tubes on the market today. The “Extreme Duty” butyl rubber uses a 3mm spec, making it 30 percent beefier than most heavy-duty tubes now available. The “Ultra Heavy Duty” tubes utilize a nearly bombproof 4mm thickness.

Economical as well as durable, the STI Motorcycle Tubes are priced considerably less than comparable rivals. STI has earned a reputation for delivering remarkably high-value tire and wheel products; that philosophy now applies to tubes as well.
