Mitas Tyres Heavy Duty Inner Tubes

The Mitas Heavy Duty Motorcycle Inner Tube is built for riders who demand strength, reliability, and puncture resistance in harsh off-road and adventure conditions. Constructed from high-quality butyl rubber, these tubes feature thicker walls than standard tubes, offering improved durability against pinch flats, rocks, roots, and other trail hazards.

Ideal for enduro, dualsport, and adventure motorcycles, Mitas Heavy Duty tubes maintain consistent air pressure and resist deformation under load or heat — critical when running lower tire pressures for traction off-road. Each tube is precision-made for a perfect fit in corresponding tire sizes, ensuring reliable sealing and long service life.

Whether you’re racing an enduro or exploring backcountry routes fully loaded, these tubes are designed to handle the abuse.
