Hello, I can’t think of a suitable title, because I’ve never seen anything like it and I can’t explain how it happens. Both tyres on my rear axle (the other one still “heal” starts with it at least…) have this “wear image” Can anyone explain to me what happened here? Luckily I wasn’t far from home and could call my wife and then drive home with a winter bike, actually I wanted to change oil and drive the engine a little bit warm. . I had heard a strange noise which I couldn’t explain at first, shortly afterwards (3-4km) it vibrated and then nothing went on! Tires completely flat and the way that looks would have flown 2sec later from the rim! Luckily I didn’t have a >200 on it!!! Now I know that the noise was the wire that scratched along the featherbone… Can’t be that the tire on the rim slipped and disassembled!? Is of course only on the inside , so where you can’t see it when the wheels are mounted. I hope you can see it, wires from the tire look out and the tire is completely melted at the rim support, or eaten up… I don’t know what to call it?! Ride an E64 650i from 2008, now with winter tires!
