Does not matter a jot, the tyre provides the puncture protection, the tube just holds the air.What are the best tubes to buy (manufacturer)? Any recommendations?
I've thought about this as well, does the 'thicker' 23 -32 have better puncture protection? If so I'm in!
Not sure its that important. I've switched to 28cc tyres a couple of months ago but still running with my 18-25 tubes. I suppose in theory that they are stretched more, but not had any punctures so far (I just know I'm going to regret posting that tommorow).
Edited to add I just stick with the wiggle own brand cheap tubes
