Think I've narrowed it down to a set of Dezent REs with Conti 830s on. Only choice now is 215/45/17s or 225/45/17s. Although I'd sort of decided on the 215s after discussions earlier in this thread, my local dealer was saying to stick to the original 225 fitting as the 215s would look a bit lost and "gappy". There seems to be about £20 difference between 215 and 225 tyres so should I be £80 bothered about how it looks for a couple of months?
