Hi ge/n/ts.
My rear wheel inner tubes are getting repeatedly fucked.
The valve patch tears out of the rest of the tube (I think on the 'back' side), deflating the wheel almost instantly.
It's now happened to three tubes.
I've re-seated the rim tape twice, lightly gluing the second time to make sure it wasn't the tape somehow dragging the tube out of position relative to the hole in the rim.
The only thing I can think of is that the tires are slipping around the rim as I apply force through them, so the rim moves relative to the tyre by fractions of a degree until it eventually drags the inner tube out of place enough to rip the valve patch.
The tires themselves are fairly old, but I've literally never heard of this happening, and I've been taking care not to break violently or try to thrash up hills or off traffic lights.
Any ideas?
Thanks.
