I’ve always had trouble with my Gazz 24x3" tyre coming off it’s bead on my Alex DX-32 rim. Has anyone else experienced this? It’s really frustrating because with the small clearance I have between the frame and tyre I have to let the tyre down and pump it up again in the right position.
Is there something I can put between the tyre and rim to keep it where it should be?
I had a similar problem with an old 20" rim. I added a strip of plastic to where the bead of the tyre sat and that helped a lot.
You can also add a dab of super glue to the tyre (10 or so small spots around the rim). I do this on my downhilling bike to stop the tyre rotating on the rim but it will hold the tyre in place too. The glue will unstick if you get a puncture or need to change the tyre.
Not unless you Brits have a different definition for ‘rim tape’.
The problem I have is that after a drop or a rough descent, I sometimes think the wheel is no longer true because the tyre rubs on the frame legs. On closer inspection though, the rim is still true but the tyre has either popped upwards from the rim on one side or down too far into it on the other.
I have done that to a Monty 20" on a DX32. It was awesome, I failed a 4 stair grind and noticed the rubber seperating. I then deflated the tire, tucked the rubber back under the rim, and reinflated. I hit the rail again, landed it and the tube exploded sounding like a gunshot.
Brian MacKenzie has the same problem with his. I rode his muni for ECMW I thought the same thing as you Andrew that the wheel had come untrue so I told him I’d true it for him. It was only a little untrue not much at all. I couldnt get the Gazz on right I deflated it and re-flated it a few times and it still touched so I left it be.
