Had a Blow Out last night managed to hold it and get the greenflag out to rescue. Got the wheel off and it appears on the tread its all fine until right at the end there is a CM or 2 worn right down, Same on the other front tyre only hasn't burst yet! Rears are fine! I'd have though tracking problems would leave it worn on the edges but specifically 1cm in is a bit weird. Any thoughts on this?
