18" Kasai's on 2003 Sedan

Just wanted a collective opinion on the wheels. I have just added a factory rear spoiler but haven't had time to get a recent pic.

Sorry but the pic kinda lacks in quality so it's gonna be hard to form an honest opinion. Maybe a close up? Anyway...they do look good on the sedan.
I was wondering what size rubber are those wrapped with? I'm shopping around for 18 X 7.5 myself and can't decide whether to with get 235/40's or 245/40's. Not sure if the 245/40's are going to be too wide for 7.5" rims. I'm just trying to keep away from the rim sticking further out than the tire and at the same time keeping the same diameter of the stock wheels.

I dont think 245 will fit on 7.5 width rims. I have 225s on my 18x7.5 rims, but might be able to go 235. I'm 99% sure that 245 needs a 8.

As for the rim, sticking out further than the wheel, as long as your tires are mounted properly to the wheels, it wont happen. And if you get 18in wheels, they're gonna be wider than the stock rim width. The 7gen Accords come on 16x6.5 if I'm not mistaken (17x7.0 standard for V6 coupe and option for V6 sedan). The 16s most likely come on 205/60/16 rubber and 17s on 215/50-55/17. Correct me if I'm worng.
