Hello All,
My question has nothing much to do with cycling but by far this felt like the best place to ask the question and get a reliable reply.
I need to replace the inner tubes on a pram but am unable to get precise information regarding the diameter of the tube I need from the instruction manual or from the tyre itself.
There are two common sizes of inner tubes for prams that are readily available 10" x 1.75" and 12.5" x 2.25". I have measured the wheel rims and the tyres on the pram in question
Wheel rim diameter - just over 10"
Tyre diameter - 12.5"
I would be most grateful if someone could tell me which of these two diameters I should use when ordering new inner tubes. I can get them for very little cost on the net or go to the manufacturer of the pram and get fleeced.
