High-quality performance: 10-inch e-scooter inner tube is made of high-quality rubber, thick and durable, heat and wear-resistant. The thicker rubber material reduces the risk of punctures and air leakage. After installation, ride comfort is significantly improved with effective shock absorption and cushioning, enhancing stability and safety. Offers better cushioning and easier installation compared to solid rubber tires. 90-degree silver valve: Silver-plated 90-degree valve design for convenient inflation. Rust-resistant and higher quality than copper. Curved valve allows easier inflation than straight valves. Excellent quality: Inner tube is made of butyl rubber with excellent resistance to penetration, mineral acids, aging, and extreme temperatures (–60°C to +180°C). Features a 90-degree cambered valve. Designed as a replacement for front/rear wheels of electric scooters. Double-layer thickness of 1.8 mm for extended durability. Valves are rust-resistant and rated for higher pressure. Wide compatibility: 10-inch replacement inner tube fits front and rear wheels of most 10-inch electric scooters. Compatible with models including SoFlow SO6/SO4 Pro, Ninebot MAX, G30, G30P, G30LP, Kugoo M4, M4 Pro, and F40. Assembly guidance: Includes 2 x 10 x 2.5-inch e-scooter inner tubes. Before installation, check for leaks by submerging the tube in water; persistent air bubbles indicate damage. Avoid using sharp tools such as sticks or needles during mounting. Do not overinflate the tube without proper tire casing.
