No, nothing like a blow out. I noticed that from the exit of the Dartford tolls to the Swanley junction that the rear started to feel like it wasn't connected to the front.
I thought the tyre was really squared off now and that I was just noticing it more. Thought, thank God I'm getting the tyres change din a few days. I thought it would have been a lot more evident if the tyre was flat.
Wasn't until I'd come off the M25 and was moving at a much slower speed and round roundabout etc that it was clerly obvious there was a problem. Stuck the hazards on a poodled the remaining couple of miles home.
On closer inpection, the centre section of the tyre looked to have blistered in a few places - I should have taken a photo.
Haven't let Essential Rubber know as I wasn't actually booked in with them to have new tyres fitted, was just going to turn up as they said they had plenty of Conti RAs in stock.
If I had more time and wasn't desperate to get the tyres on before WSB on Sunday then I could have maybe saved a few quid still.
