I'll likely try 225/40/18, as I'll have a Limited with the larger wheels. More than likely, most will aim for the 235 size though.

I’m torn between 235 and 245 660’s. I have 17x7.5 +48 RPF1’s and a 6mm spacer with extended studs to get close to max legal offset.

My concern on the 245 is it might rub the front shocks. Not sure how close that’ll all be with the oem crash bolts.

I looked up falken's recommended rim widths for the 235/45/17 RT660, and it shows a 7.5 as being the minimum width they recommend, so I'm a little worried a 245 will feel like a balloon lol.

Eh, it’ll be fine, on my old GS Si I ran a 255 rt660 on an 8. 245 on a 7.5 is similar. They don’t seem to mind being pinched unlike the yokes.

I think discussing aftermarket tire sizes on this thread is pretty off topic. I gave links to more appropriate threads above.

You linked STX threads which are also off topic.
