Attributes

Description

Quantity: 1, Compatible Models: 3.25/3.50-16, 90/100-16. 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. Lot Number: 22374415, Brand: CPPZAHD,
