I've been looking at the nitto 555 and know for sure than on the rear ill be running a 305/40/18 size, now regarding the front i dont really want to run a 255/45/18 because IMO i think the smaller sidewall on the rear compared to the front looks funny. With that being said, Im really considering running a 275/40/18 in the front. Now my question is '' Can i run a 275/40/18 front and 305/40/18 rear with no rubbing issues im also running prokit springs.

Edit: The wheels im purchasing are the saleen s style

Thanks:
Mike

 

Umm the sidewall between a 305/40/18 and a 255/45/18 are going to be very close. And if anything the rear might be a little bit taller which would help fill out the extra gap in the back fenderwell.

Look at cars with 255/45/18 and 285/40/18. There are lots of them around. Looks fine to me and very difficult to tell apart from stock as far as fender gap goes.

 

Both the 255/45/18 and the 285/40/18 are 27 inches tall, same as the 235/50/18 stock tires so the sidewalls are the same height. I think the 305/40/18's are 27 inches also.
