Hit something the other night and did this to the front right tyre.
This particular tyre is now discontinued despite only being 6 months old (and only covering about a thousand miles) so looks like I'll be buying a pair of new ones.
I've searched all the online suppliers I can find, and they're all stocking the new version. My local tyre fitted has also drawn a blank. There's a pair of part worns on Ebay for £90, and that's about as good as I can get. Not buying second hand ones though.
