Had a mobile fitter try fit winters to my 108's... Spent an hour got one wheel done... And took the rest away as his tools in the van were not good enough!
I bought my Vreds from Blackcircles and had them delivered and fitted at Protyres on the A10 by Carterhatch Rd. I'm sure you've been past the place.
Very pleased with the service and they didn't put a mark on my 108's even though they had to remove the run flats.
Doesn't help you now, but a recommendation for next time.
