oldjohnno Posted 9 hours ago Share Posted 9 hours ago 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 1 hour ago Share Posted 1 hour ago 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...
