i would recommend against 255s. i had 255s on my BBS wheels at one point. it was very mushy and unresponsive feeling. the sidewall was very straight, if not a little ballooned out..i can't really remember exactly, as it was about a year ago.
my next set was a 245 tire on a 9" wheel. it had a slight stretch, so the responsiveness was night and day. it was very precise and felt like a completely different car.
a lot of people bag on stretched tires, but if you look at a lot of road race/time attack cars, they run a narrow tire on a wide rim. the Cyber Evo comes to mind. i don't mean "drift" stretched, but just a bit. i'd post a picture, if i could find some.
cyber evo runs 255s but on a 9.5" wheel. slight stretch.

I had the same experience. I put 255/40's on OEM BBS's, and I didn't like them one bit. Definitely 'mushy and unresponsive' as you put it. I very quickly found a 9.5" wheel, and it absolutely transformed the tire. The stretch is very slight, but it feels ten times better. The steering is much better and the wheel doesn't feel like it moves around on the tire like the 8" wheel did.
My wheels are +25 and fit, as long as I don't lower the car too much, but they are 10". Yours should be fine.

^ummmmmm, yeah, that tire sux. Tires with stiffer sidewalls like the Z1 star spec are better for running a 255/40 17 on an 8 inch rim (although an 8.5 or 9 inch would be ideal). Many people have run 255/40 on stock wheels for autox with much success for years and years.
and just because many have done it doesn't make it work any better.

I'm not trying to say you are wrong, just that most serious motorsports driver's may disagree. After a short bit of Googling, I have yet to find any teams/cars/drivers using a 255 on anything less than a 9"wheel.

many many people have been running a 255 tires on an 8 inch wheel. I know smike had done that with much success. it all depends on what your application is for, and if for racing what the rules are.
personally I like to get as much tires and as big of a contact patch as possible with the appropriate camber. that being said, a proper sized wheel will help with that. there a fine line between putting too much tires on a small wheel and being hella jdm flush.
a 255 sits perfect on a 9inch wheel from a performance standpoint. I personally run 265 Z1s on a 9.5 in wheel. no stretching, stiff sidewall, handles great. its all about goals for the car, tire, wheel size, sidewall stiffness, rules etc. to each there own!

LOL, I think we are all thinking and agree on the the same things guys. Personally I run a 255/35 on my 9 inch Advan (cuz it fits the best). I was just saying that a 255/40 on an 8 inch is done a lot and is proven to work well given the right tire and application...

currently im running evo x wheels w/265s on my 9. i have coilovers, no fender mods, and no rubbing whatsoever. the clearance is tight but there are no issues. if i downgraded, will mr bilsteins+ tanabe gf210s work with my wheel/tire combo without my tires rubbing? i know they will fit with 245s but idk about the 265s
