Heavy Duty Mountain Bike Tubes

Hard off-road and heavy riding require durable tubes. With 16 years of experience in inner tube production, we know what works. This heavy duty mountain bike tube is designed for tough riders. Made from high-strength butyl rubber with a wall thickness of 1.2 to 1.5 mm-nearly twice that of normal tubes-it resists tears and punctures effectively. Riders can tackle trails, gravel roads, and steep hills without worrying about cuts or pinch flats.

Available sizes cover wide tires for 26, 27.5, and 29-inch bikes, with widths ranging from 2.125 to 2.4. Valves come in 32 mm and 48 mm, compatible with high-profile rims. Air pressure ranges from 25 to 45 PSI. Low pressure combined with thick walls provides excellent grip, and the tube resists bursting. Our R&D team has refined the rubber formula multiple times, giving better aging resistance than standard butyl, with users enjoying one to two years without hardening or cracks.

Our factory has a monthly capacity of 1 million units, allowing most orders to ship within one month. The MOQ is 10,000 pieces, and different sizes and widths can be mixed. We support OEM and can print your brand. Quality follows national standards, with 100% full inspection before packing. Third-party inspections are welcome. We offer a 3-month warranty. Free samples are available, while custom samples take one week. Payment terms are 30% in advance and 70% before shipment, accepting USD. We ship DDP to your warehouse and provide live production photos. This heavy duty mountain bike tube is ideal for bike shops, clubs, and heavy e-bike users.
