Maxxis 2.50-8 Heavy Duty Inner Tube with JS87C 90° Bent Valve

Stop fighting tight rims and hard-to-reach valve stems. The Maxxis 2.50-08 Inner Tube is engineered to deliver maximum durability and hassle-free inflation for small dirt bikes, pit bikes, and electric ride-ons.

Featuring Maxxis’ premium rubber formulation and a JS87C 90-degree bent valve stem, this tube angles outward away from wheel hubs, brake rotors, and chain sprockets—making routine pressure checks and pumping air effortless.
