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 excellent 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 valve with 90-degree angle design for convenient inflation. Rust-resistant and higher quality than standard copper valves. Curved valve design allows easier inflation than straight valves. Excellent quality: Inner tube made of butyl rubber with strong resistance to penetration, mineral acids, aging, and extreme temperatures (–60°C to +180°C). Features a 90-degree angled valve. Designed as a replacement for front/rear wheels of 10-inch electric scooters. Double-wall 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 Segway Ninebot MAX, G30, G30P, G30LP, Kugoo M4, M4 Pro, F40, and others. Installation and support: Includes 2 x 10-inch x 2.5-inch e-scooter inner tubes.
