RE: Tire sizes
Its pointless your likely to have the tread just roll over and become sidewall because they have to shoehorn the damn tire onto the rim. If you want bigger tires you need bigger rims IMO.
I'd agree with the 255/45/18's on the 18x8.5" wheel and have heard 275/40/18 for 18x9's.

RE: Tire sizes
To much sidewall flex. I run 275/40/17 Drag radials on the Stock 8" rim, but dont drive them to the track, I install there. Too small diameter, pluss too much sidewall flex. You will lose handling with a tire thats too wide for the rim.

RE: Tire sizes
Check out this site http://www.1010tires.com/TireSizeCalculator.asp. Plug in your current tire size and your desired tire size and it tells you if it will work and the rim width necessary
According to this site your best bet on 17 X 8.0's is a 255/50/17. This size tire will actually improve your gear ratio.According to this web site, it is also okayto275/50/17 on your current 8.0 rims, but the diameter of this tire is bigger so you will lose gear ratio. For those of you reading this post with 18 X 8.5, this siterecommends 9.0 inch wide rimesto run the 275/40/18. I would assume this is because the 275/50/17's have a taller profile to spread the extra width over. Personally, I set my highly modified suspension up for a street/road race application,so I run 255/45/18's. One can always through on a set of drag radials at the drag strip.
