12 1/2 x 2 1/4 Inner Tube with 70 Degree Bent Valve replacement inner tube suitable for smaller wheelchairs with 12 inch wheels.

Before installing inner tubes run your hand around the inside of the tyre to ensure your tyre doesn't have any stones or sharp objects that may puncture the brand new inner tube. If you decide to use objects to help fit inner tubes please ensure only blunt objects are used due to the fragile nature of the inner tubes. Using sharp or metal objects will pinch, puncture or pierce inner tubes. Only pump inner tubes up with a hand pump to avoid over-inflation.
