Thanks for the write up on your experience so far. I was really not expecting any (20" in my case) run flats to be that good but I have been very pleasantly surprised with how good they feel. Yes on some road surfaces they are a little noisy but then so are normal tyres. Before buying my 640 I read many reports of 20" wheels and run flats being a very bad idea but so far I have been very impressed. Hopefully this will continue as the tyres wear down.
@idrussell Mine are slightly smaller than yours at 19 inch, with 275 rears and 245 fronts so which is probably a similar width to yours, I have had Goodyear NCT 5, Continental sport contact 5, Michelin primacy 3, Dunlop sport max all in runflats and two different sets of Dunlop winter runflats of all of them the contis were probably best for ride quality and low noise levels but they were let down by the speed they wore out, The rears were down to 3.2mm in 10K miles and at £200 a pop i would like a little more miles for my money
I’m needing new tyres and currently have Dunlop sportmaxx gt. I have been offered a pair of Michelin primacy hp runflats cheaper than the Dunlop’s but not sure whether to stick with the Dunlop’s or try the Michelin. Anyone any experience of the Michelin hp’s?
I have goodyear runflats on my 320ed was brilliant, car had 29k on when sold and i reckon they had another 1-2 years before needing to change depending on mileage covered. I think they were Goodyear efficient grip or similar name? I forgotten exactly now. My current car has Bridstone's and they are not great, i'm just living with them until they are low enough that I can change them for potentially Goodyear but I suspect that's another 1-2 years also as i think the rears are now down to 4-5mm (depending on what tech does the health check ) I never noticed any delamination on my and was never mentioned when it went in for servicing etc. Kev
