2-Pack 3.25/3.50-19 Inner Tube 90/90-19 100/90-19 Dirt Bike Tube TR4 Straight Valve Stem

• Compatible Models: 3.25/3.50-19, 90/90-19, 100/90-19.
• High-quality inner tubes are oxidation-resistant, high-temperature resistant, have high air tightness, and stable tire pressure, making them suitable for extended working hours.
• The TR4 straight valve boasts strong sealing and multiple reinforced designs at the interface, maintaining stable tire pressure for an extended period after inflation, reducing the frequency of routine maintenance.
• The inner tube, after inflation, possesses a certain degree of elastic deformation, providing stronger traction on soft sand, mud, or gravel roads, reducing the risk of slipping and getting stuck.
• Avoid using sharp tools during installation to prevent scratching the inner tube. Inflate slowly at the beginning, observing whether the inner tube expands evenly to prevent localized stress and rupture.
