Weird wear on rear tube.
Posted: Thu Apr 27, 2017 11:25 am
Me and my wife have just returned from a week long trip into Scotland, Oban area this time, and on the way back my wife suddenly had a rear flat on her XRV750, we managed to struggle into the Costa coffee car park though :laugh:
No problem I thought, remove panniers and wheel, then pop the bead and out with the tube only to find no sign of a puncture from the tread area :huh: so I looked round the tube and found the texture from the Michelin tyre had worn into the tube in two rings on each side and this wear had got deep enough to break through in one spot causing the flat.
Quite a difficult area to patch and the patch wouldn't have full support from the tyre as it was in the transition from the tyre bead to the rim, no spare tube so a patch was applied, tube refitted and the tyre blown back onto the bead with the help of a bottle of water and shampoo and the little compressed gas canisters I carried (more on them later). A slow trip to the next garage to check the pressure and off we go again. 2 miles later it's going flat again so pull off the road and sure enough the patch has been scuffed by the movement and has come away, fortunately we are just outside Ayr and the local bike shop was still open so I pop off to get a new Michelin airstop tube and more canisters, get back, fit the tube and all good with a new quality tube fitted and the tyre blown up to the correct pressure using a pump that a kind local lends to us. All's good now and I'm happy that it's got a new tube in so no need to change it now we're home.
My conclusion from this is that the canisters aren't worth bothering with so I'll be buying a small electric pump or a good cycle pump.
However has anyone else seen this type of wear on a tube?
The tube was new and fitted at the same time as the tyre some time around the middle of last year and they have only done a couple of thousand miles since, always been run at or near the correct pressure, I do check it regularly as it's my wife's bike and she'd ride off on a near flat tyre and wonder why it was handling funny.
The tyre is a Michelin Anakee 3, tube was a V rubber and didn't feel thin compared to the Michelin and I've used them with no problems before, I've heard of seams splitting etc but this was definite wear from the texture inside the tyre. Unfortunately she threw it away as we were a little tight on space and I didn't think to take a photo at the time.
