A replacement inner tube in size 4.10/3.50-4 with a TR13 valve for compatible mobility scooter wheels. Supplied as one tube. Match the tyre size and valve arrangement to your wheel before ordering.
Frequently asked questions
How do I choose the correct tube?
Match the complete size marking on your tyre and the valve type and position on your existing tube. The wheel diameter alone is not enough to confirm fit.
Will this fit every wheelchair or scooter?
Fit depends on the tyre, wheel and valve arrangement. If you are unsure, send us a photo of the existing size marking and valve before ordering.
