what tyre and rim is it sm or standard ? find with standard no force is needed to get tyre back on so no nipping tube you can just use body weight to walk round the rim and pops back on ...
i have had the rear tyre replaced- coulpe days ago..straight away it went flat- garage said possibly nipped the tube going back in. so they changed and also said posibly the spokes may have caused..they were a bit rusty so they clean off the rim and put tyre and tube on.. 2 days it has lasted? is it possible they nipped inner tube again? cant see it being spokes as the tyre was fine with previous one on?? gonna take to proper bike shop to change tube and see what they think, any thoughts folks?
Spokes if you ask me! they might have nipped it again but you would like to think theyd go careful a second time round! Take it youve checked the inside of the tyre too? if you havent already taken the tyre off mark the tyre with a dry wipe style pen thing (sign writers one) with like a numbered clock face and mark where the valve sits in relation to the tyre too...that way when you take it off you can match it up, see where the puncture is and then inspect that area of the wheel and tyre...if you had old innertube you could also see if the puncture is in the same place....
