I've decided to fit Avon ZZ5's for a few reasons. I've got a holiday to pay in full in the next couple of weeks and spending a lot of money on the house so I had a budget of £1000 in total. The tyres are coming in at £435, fitted from National Tyres by their mobile unit so don't need to fanny about taking wheels up and down to them. I had the same tyres on my 350Z and didn't have any problems with them and they seem to get reasonable reviews. So in total £550 for wheels, £435 tyres and about another £12 for centre caps and m badges from Ebay means £997 total so worked out ok. I've went for 235 35 19 and 255 35 19 as mr Wilks suggested. It'll be interesting to see the difference going from 17" runflats to standard 19s.
