Fitting different sized tubes on thinner tyres

The Tricross is 32, I want to get some spare Botrangers, since they are supposed to be decent and Cycleworld have 3 for 1 at the mo.

However, the range is 35-43 - Can I use it on 32? The road ones are even smaller, obviously, maxing out at 27.

What to do?

To be honest, I don't fancy getting a bot ranger, let alone three of them, but, hey, each to their own...

due to my recent encounters i would not recommend getting inner tubes bigger then the recommended tyres, firstly because my soma everwears ripped on the side beading and part of the inner tube was sticking out, this could be due or not to the inner tube being too large over a long period of usage, and secondly because getting the inner tube into a deep v, which is what i use meant that where the valve enters the rim the inner tube gets like sqaushed and can pinch really easy and it can be long and annoying to fiddle around with but if you dont mind htfu'ing up and these dont apply to you, why not?

For some reason these were not on the main page, but it looks like I can get 32's after all.

What a steal!

I know there's variables but what's the likelihood of a 700x28 tube going into a 23 tyre? Rim isn't campag, tyre isn't Conti.

Don't pinch it and it should be fine.
