Back in the day I (as did many others) put Fire XC Pro's on my trusty steed - you remember, the ones with the godawful red stripes. For whatever reason, and despite much fettling and playing with pressures they just didn't get on with my rear rim. Any rear landing more than a tad off straight and they'd roll off the rim. No-one I know had the same issue. New rim tape, tubes, everything. Wheels were as true as they could ever be. Was absolutely trying to kill me, so I swapped out for a some new wheels (man maths obvs) and the issue never came again.
