Change an inner tube on a Trionic rollator – Assembly Instruction

Pop off one side of the tyre, and remove the punctured tube. Don’t forget to check the tyre for what caused the puncture. Gently run your finger around both the inside of the tyre and the inside of the wheel rim to make sure there are no sharp objects or edges that could puncture the tube when it is inflated.

With one side of the tyre still on the wheel, slightly inflate the new tube and push it into the tyre. You can use tyre levers to get the second side of the tyre back over the rim but, again, be careful not to nip the tube.
