oldjohnno Posted yesterday at 05:21 AM Share Posted yesterday at 05:21 AM I have a recurring issue with the rear (tubed) tyre becoming partially unseated. There's no problem with getting it to seat initially - a bit of lube, inflate it to 60 or 70 psi and it pops on nicely, all the way around. The problem occurs after I deflate it to my normal pressure (4 psi) and ride it. A section of the bead slips off its seat, about 250mm in length. I can reseat it easily but when I deflate it back to riding pressure and ride the bike it happens again. The rim looks fine, as does the tyre itself - both are fairly new. Suggestions? Superglue and self-tapping screws? Quote Link to comment Share on other sites More sharing options...
mcman56 Posted yesterday at 12:58 PM Share Posted yesterday at 12:58 PM I had that issue with a vintage bike. It looked like it unseated in the area of the rim weld. The weld did not look that bad but I took a file and smoothed it out as much as I could. That eliminated the issue. Quote Link to comment Share on other sites More sharing options...
lemur Posted 1 hour ago Share Posted 1 hour ago Add another rim lock right where the tire pops off the rim bead, if the rim actually has a bead. Guessing it is a steel rim with no bead, guessing you are running a tubed type tire on it. In my experience there is only one adhesive to safely use in tire applications and that is Fish glue. The up side of Fish glue is it's non-flammable and water soluble and re usable, the down side of Fish glue for your application is that it's water soluble. Fish glue is a fast drying, cold set, highly flexible adhesive largely used in woodworking. Quote Link to comment Share on other sites More sharing options...
