Serious problem with my tyre!

GSJ

I got a flat inner tube on my front tyre, and I've taken the inner tube out and everything followed the normal procedures, however. When I place the new tube onto the rim and tuck the tyre in it's slightly up from where the valve is. I've taken some pictures so you know what I'm talking about. I've tried about 6 times taken the inner tube out, pumped it more pumped it less and it's doing the same thing. My palms are sore, my fingers are bleeding! I can't figure out why it's doing it (This is my first tyre change)

It may sound silly but... Have you taken the nut of the valve, it should just unscrew, before fitting the inner tube?

Can't really see from the picture.

Pump it up a little bit, then push the valve stem in and out a few times - you've probably got a bit of tube caught up in there and flexing the valve in and out should free it up

Yeah the nut has been taken off.

^^^^^^ This, push the tube into the tyre then push the tyre into the rim and inflate and check again.

^^ Agreed, but you should try to find the nut to put back onto the valve stem as well....

start with the valve stem almost entirely inside the rim, not poking out as far you have got it. that valve area is a thicker that the rest of the tube, take it out and have a feel of the tube, its less flexible and less likely to to fit snugly inside the tyre bead than the rest of the innertube. you need to be sure the tyre is over it and then jiggle it onto the rim properly. side to side and slide the tyre slightly around the rim to ensure a good seat. make sure that the valve stem still comes out of the hole straight though once you've jiggled the tyre on.

problems if you don't get it right: You risk trapping the tube between the tyre and the rim if you leave it like that, it'll be guaranteed to puncture and will most likely look like a snakebite with 2 v close together holes - this can happen anywhere round the rim and tube though, you need to be careful with the whole tyre circumference not to trap a bit of innertube, this is why thumbs are better than levers for installing tyres. Worst case, the tyre won't be seated properly onto the rim bead and could blow off in quite a spectacular fashion.

Agreed. You need to find it to chuck it in the bin so that it doesn't get in the vacuum cleaner.

Valve nuts have no use or place on a nice bike. It's even mentioned in The Rules I believe.

Well, just take you time and yes using plastic levers aint a crime..

By the way the tyre in the vid has been off and on a few times.. hence its ease on going back on...however as all you are doing is pinching the tube, just a bit of patience is required....

Which is as good a reason as any to make sure you have the valve nuts on
