ohhh my 6p's worth..
ran Panaracer Cinders for a while. They were ok. Switched to the STW combo of Nevegal/Blue Groove however this happen to three tyres
that one didn't fail compleatly but is unusable, the other one did when I was out and about. and was replaced, the replacement failed, There was plenty of tread on the tyre's when they went.
Same thing also happened to another chap I was with as well.
Switched back to panaracer, but the Rampage and I love it. good all rounder for me in the Peaks
