Dirt Bike Inner Tube with Heavy-Duty Butyl Rubber and TR4 Valve – PIVOTRAX Eight Size Options

Dirt bike inner tube provides an air-retaining replacement for compatible motocross, pit-bike and off-road tires. PIVOTRAX offers eight diameter and width combinations, allowing riders to match the tube to the tire markings, rim size and existing valve position.

The detailed 3.00-12 or 80/100-12 variant uses 2 mm butyl synthetic rubber and a heavy-duty TR4 Schrader valve stem for impact resistance and consistent air retention on trails or tracks. Other listed options cover 10-, 14-, 16-, 17- and 19-inch wheel sizes, and their dimensions must be selected independently. Read the tire sidewall and old tube before ordering, confirm the rim’s valve-hole type and never substitute a nearby size based only on motorcycle model. During installation, avoid pinching the tube, seat the valve straight and inflate to the vehicle or tire manufacturer’s specified pressure.
