I'm planning to change my current 17" S-Lites on my MCS to the new JCW 18" wheels.
They are bigger but still lighter than the S-lites and of course they look the part. I would like however to not have the runflats installed but on checking the faqs I see there's only tires in the 215 size for 18" wheels. Isn't there any 205 non-runflat tires for 18" (JCW) wheels? If so what do you recommend?
I figure I could save a few more pounds/kg per corner ending up with a sportier look and lower unsprung weight to boot!
i've been lookin into this also. bmw were very helpful and said that they could only supply run-flat tyres but if i bought the tyres elsewhere they would be happy to fit them for me at the same time as the wheels.
i asked about 215/35/18 and 215/40/18 and they said both would be fine.
might vary from dealer to dealer so i'd check first.
I followed this thread with some interest but all seems to have gone quiet. Maybe it's the Christmas effect. Does anybody have some new thoughts on the question of non-RFs on the JCW 18s? Anybody running 215/35-18 Toyo Proxes T1-R?
Cheers Redun I have the 215/35 R18 Falkens 451's, and they're reinforced (where the Toyo's are not ) and the ride is 1000% better, and 1000% quieter then the RF's. The Tyre technician at MINI said although the tyres are not runflats the reinforcement helps if I say have to do a few miles on a flat. The tyre would be ruined but the rim should still be protected from all but the worst surfaces.
However the grip in the dry isn't quiet as good as the dunlops, but then again 5000 miles out of the dunlops is pathetic, Ive already done 10000 miles with these and expect another 7 or 8 k.
I replaced my Dunlops with 215 40 18 non runflats and 4000 miles later they are fine - as new infact which is more than I can say for the Dunlops. They are cheapo Wanli S1099 tyres I think they were about £70 each.
