Hi Guys

I have just got some 20" Kahn alloys for my SC430. They are 8.5j all round.
Does anybody know what size tyres would give me the best set up on those wheels. The car is on standard suspension.
Currentley they have 275/35/20 dunlop tyres. would any other size setup give me a better ride.
Regards
Charles.

did the wheels come with the tyres for your car or another one?

I am surprised that they have 275 fitted. That seems a tad wide for 8.5j.

Hi Guys,

The tyres were on the wheels when got them. They fit fine with no rubbing etc. Just wondered what the ideal set up would be thats all.
Cheers

I would suggest that 245 may be a better width,possibly 255 at a push. 275 is too wide for that size rim and would normally be fitted to a 10j not 8.5j.
Hope you get it sorted to your satisfaction. Your wheels look good.
