This Universal Parts 2.80/2.50-4 inner tube is a practical way to get your scooter or small utility wheel rolling again after a flat. Its 90° bent Schrader valve makes pump access easier around tight hubs, while heavy-duty butyl rubber provides dependable air retention.

  • Easier inflation: Bent valve stem improves pump access where a straight stem is difficult to reach.
  • Multi-size coverage: Fits compatible 2.80/2.50-4, 9x3.5-4 and 3.00-4 tire setups.
  • Butyl rubber construction: Combines flexibility with dependable air retention.

Model Fitment

Application Fitment

Check the tire sidewall size and compare the original tube's valve position before ordering. 

Installation and inflation: Give the tube just enough air to hold its shape before fitting, and avoid trapping it under the tire bead or between split-rim halves. Follow the vehicle or equipment manufacturer's operating-pressure recommendation without exceeding the tire and wheel limits. Fully deflate the tire before separating a split rim.
