Thought I'd posted this morning..... but it obviously didn't survive the DLK crash ..
Tyre has a large split on the inside shoulder, with a diagonal cut leading to it.. I'm guessing the cut was something picked up in the roadworks that caused the failure, the rest might well be "rim damage" as the car had to be moved on the very flat tyre.. at one point I thought it might come off, but it didn't. .... no screws /nails or anything suspicious at all.
Other side is definatley OK ... checked the pressure this morning ... 45 psi - which before you yell is the correct pressure for fully laden - I always inflate before towing and let them back down once home

It must have been the camber of the drainage gully that made it look half flat
Tyres needed replacing anyway .... as a certain very knowlegeable moderator chap pointed out ..

2 new Falken FK452 s being fitted tomorrow at £200 all in .. not having Avons again they've only lasted 9000 miles !!!
and it was all going so well ....
