Can you elaborate please. What do you recommend for wheel width and offset specs for those tire sizes?
Stephen has the 275/40R18 on his car, I'm thinking that he just made a mistype with the 45.


The options for larger staggered tire sizes in 18" are diminishing, the only ones in the 255/45 & 285/40R18 combo I'd currently recommend are the latest from Continental, the ExtremeContact Sport. Very nice street tire with good dry & wet grip, and could be used for autocross or track days … bearing in mind that you won't keep up with people that are running the max effort stuff like the RE-71R.

Another option for staggered is to go with 245/45R18 and 275/40R18. Still not ideal, but better than your OEM 235 tires. Those sizes are much more common, and give you many more choices for brand and model. An excellent option at a great price is the Firestone Firehawk Indy 500, which are made from the same carcass as a Bridgestone RE003, one of their tires not sold in North America. These are impressive performers, especially when the price is factored in.

Wheel sizes needed would be 18x9 with offset in the +35 range, and 18x10 with offset in the +40 range, give or take a few mm either way.


if doing the 275/40R18 all around, then you should have 9.5" or 10" wheels with offset in the +40 to +45 range.
