It was suggested to run 255/285 stagger by the poster I responded to which is all good, except no one makes a 285 in a 17, hence my response. A 275/40 - 315/35 is 25.7" overall diameter. Which is 1" larger circumference then the factory 245/40 or 285/30/18. This is typically a compromise to increaser the sidewall that much. It adds weight, it can add sidewall deflection and it lengthens the gear ratio for less acceleration. If you don't care about a couple added pounds and the gearing change, like the cheaper tire selection over 18's and still wanting to build an all out grip monster without having to run R comps on the street, then maybe like myself you are willing to deal with the compromises of running a 275 or 315.

Manga you need to drop that thing another smudge. Looking a little 4x4, or maybe just 2x4

Yeah I have just been lazy. There is something really nice about not scraping on everything though. I have a list of little projects I need to do on the car here soon and lowering it a bit is one of them.

Ahh cool. Guess will find out what else you doing soon enough. Id run some kind of lip protector under that front end to help cover your ass. I just sent Bryan a link to a company that makes them to protect the ap2 lip. Those stick out about an 1" and may sit pretty damn flush on your front end so likely wouldn't even see it but protect from scraping paint underneath/tip. $100 is all they want.

Interesting. A 245/40 17 has an overall diameter of 24.72 inches, 77.65 inch circumference, 3.86 inch side wall and spins at 816 rotations per mile.. The 275/40 has a 25.66 inch diameter, 80.62 inch circumference, 4.33 inch side wall, and spins at 786 rotations per mile. Would this be an optimal pairing if I'm willing to accept those compromises? Also, I would have to find a wheel with a higher offset to fit those tires, correct? Something like a +45 or +50 for the rear and something similar for the front? Assuming I kept the 1.5 inch difference in width from front to rear.. (17x8.5 front 17x10 rear) ?

Its not a great pairing generally no. A 255/40 would be about as extreme as I would go front to back for a stagger of 25" to 25.7" Even then its not great, but 245/40 would be too much for my liking. Someone Still makes a (265/40/17 ...Z2?) which could be an option for the front to pair with a 275 rear.

As far as rim widths and offsets, all depends on the tire width you decide to go with. For a 255/265 id go between 9.5-10" wide. For a 275 10" to 10.5".

8.5" works on a 245, but 9" would be better/optimum, and can go as far as 9.5" without the sidewalls getting over stretched.

+45-+50 would be the offset range id shoot for with a 10-10.5 with a 275 yes.

Totally forgot he listed his wheel size (and it's in the title ).

If that's the case, 255/40/17 and a 235/45/17 would be a good mix.

Personally Id prefer the slightly shorter tire up front with the 235/40 or 245/40 rather then larger 235/45. Better turn in response/handling and brake bias stability.

Alright, so I want to start off by saying thank you for all of the input. As it sits, I think I've decided on doing a 17x9 +60(ish) on the front and a 17x10 +50 for the rear. Going to run a 255/40 275/40 respectively. From what I've read the only thing I really have to worry about is the possibility for a little rubbing in the front on the control arm at full lock. Would a slightly lower offset maybe correct this? I know +45 is a popular offset for a 17x9 on the front, but I've also read that it can be a bitch and a half to fit a 255 on it. My front end is stock for the moment, and I would like to avoid rolling/pulling if at all possible. Mainly due to the fact that I've just relocated and don't have an ounce of trust for any of the shops around here..
Thanks again!

There is no rubbing issues on the inside control arm at 9 +60 and any discrepancy there with alignment and ride height you are far better off rubbing the inside then the outer fender. With a 255 up front 9 +60 would be optimum for stock rolled fenders, no pulling. If your not rolling the fronts then run a 245 would be best to avoid outer rubbing issues assuming you are moving up in spring rate over stock and not lowered more then 1.5" - roughly 1.5 finger gap. That's not going to be a great pairing to a 275/40 out back with wide fenders though. Get some DF front fenders and do the 255's with a slightly more aggressive offset or rim width, will be more balanced looking then having an aggressive rear end and stock up front.
