The factory 18" rear wheels are 11" wide so you are limited to how wide you can go. Best bet would be 305/35/18 on the R888R, they will be a little wider than what you are running now (12.4" vs 11.9") and the sidewall hight will be close, but slightly less by about a 1/2" shorter in height (26.3" vs 27.3").

The 315/30/18 will fit on 11" wheels if you wanted a even wider tire, but the sidewall height will be very small (25.5"), meaning your revs will be up significantly vs what you are use to now... also, I don't think most cobras look good with low profile tires unless you're shooting for the modern look.

You can do what I did and have you wheel's widened by one inch and then you can run 335/30/18's and get huge footprint with decent a sidewall height of 26"... this tire size will not fit on factory width wheels. You could cram them on but it wouldn't be correct and you'd get bulge and possibly fender rubbing as they would stick out far from the outside wheel lip.

Front tire size stays the same.

I'll throw a few pictures in of my custom widened stock rear wheels and 335/30/18 R888R's...
