Later this summer I'll be replacing my 235/45 PZeros and I'm going with 225/45 in the front and 245/40 in the rear. I'm going with Sumitomo HTRZIIIs which are highly rated in TireRack's comparison test. The fronts are 25.9 and the rears are 25.8. The PZeros are 26.2 which is OEM size. I'm choosing the fractionally shorter tires because:
1) More selection, cheaper
2) Will look better. The 235/45s look too tall, IMO.
3) Lighter
4) Shorter sidewall means better response on turns.
IMO, a 245/45R18 will look like a ballons. The 8.5 rim should help a little, but they'll still look pretty tall.

1. 245/40 and 245/45 have a lot more selection VS the 235/45 for STOCK
2. looks that can do either way...
3. its not a big deal to me.
4. this is what i'm more interested in. You was refering to tires making a huge diffrence and making the G handle like a stock STi, would either of those 2 sizes make any diffrence? because if not i'm running with the 45 sidewall for more comfort.
I have the stock 245/45/18 that came on the 350z still mounted on the rear tires. to me they look fine. I'm not trying to make it to the hella flush movement or anything. I just want something that works.
In my mind right now if i can rework my car with what i have, i might like it and hold on it to more. on the side note i found a LGT wagon and a magnum hemi on the same dealership lot. so i can test both.

i am going with 245/45/18 and 275/40/18 on my G35X. i have lots of friends running AWD cars and as long as the overall diameter front to rear is virtually identical you can run a staggered set-up. 
There is usually coop interships and such associated with the college time. It's a lot of math and theory.
haha, no i mean one of my friends is at MIT and he and one of his friends is gonna get a contract with Fedex to retrofit their engines. We're talking about a multi-million dollar deal for an undergrad. all he does is business stuff while his friend does the mechanical stuff. i'd love some easy money like that
