Which inner tube - confused

[SirDickieBird]

Sorry, I've searched but can't find the exact answer.

I believe I have 32mm tyres so looking for inner tubes.

Which do I get between:

- 700 x 25-32
or
- 700 x 32-47?

Obviously one has 32 at the top end one at the bottom - which will be best? Easiest to fit? Or no difference?

Either or.. they'll both be fine

I'd go for the first to be honest. Both will fit but i think fhere's a chance that the second may be a bit of a struggle/demand extra care.

Only reason i would go for the other tube is if it might be handy for bikes you have with fatter tyres. Always a good idea to simplify the spares box.

 

[Supersuperleeds]

Either are fine but looking at some of your other threads I suspect you will be going to narrower tyres at some point so I would go for the first one.

Just check that your tyres are definitely 32mm, I didn't thing a larger volume tyre would fit on the Carerra you have.
If they are go for the first.

The number is the ERTRO system for measuring tyre size

The first number is the diameter of the wheel and is fixed

The other is the width ion the tyre and is (within reason) changeable, Inner tubes are more flexible (Literally) and so can cope with a range

The only real problem with using a tube much larger than you tyre is that there is more material and a "pinch" puncture where you catch the tube when refitting is more likely

 

[Vantage]

Go for the smaller tubes. They'll take up less room when stored as a spare and will stretch beyond the 32 top end size easily. The bigger tube might be more prone to catching between tyre and rim when fitting.
