Hey,

I am guessing I can fit 02-03 sc430 rims on a 92 sc400. They are 18x8 inch rims. My question is on tires. What should I run? Should I just run 245/40/18's all the way around? Could I and not get rub? Or should I do something like 225/40/18 front and 245/40/18 in the rear? On 8' rims I really can't go larger than a 245 can I? I would think a 255 would be pushing it. Anyway. Hope some tire experts can help me out.....thanks!

I have 245's on 8 wide wheels on the front of my 300, so I would assume you wouldn't have a problem with that.

I wouldn't put 255's on an 8 wide wheel. In my experience you would be stretching the tire beyond what it should be, and you will end up ripping tires after enough impact.

Do you think I would be able to get away with upsizing a little and running 245/45/18 's all the way around and not rub? Just curious, because I really do love the big rim, big rubber look a 45 profile offers. Thanks

I'm not 100% certain because I havent' done it or seen it myself. It's not that much of a difference in diameter and the wheels aren't that wide so I'd say you would be OK with that. Always test fit before mounting all four tires though.
