You can scratch all of the above wheel options unless aftermarket wheel companies produce those wheels specifically for the GTO. No current GM wheel or replica will fit because the GTO has non-standard GM lug spacing. Also GM put 245's instead of 275's because they bigger wheel/tire combo will rub.

275's will fit on rear. As posted by Howie on NewAgeGTO.

Ask and you shall recieve, results of yesterday's wheel & tire test fitting w/ ROH wheels:

Factory wheels & tires:
17x8 w/ 245/45/17
55lbs each (wheel & tire)
5x120mm stud pattern
48mm backspacing

17's
Front:
245/45/17 is still the best fit
255/40/17 fit but had to use a 8.5" wide wheel, the required backspacing hadthe wheels/tire sticking out too from the body line
275/40/17 didn't fit, using a 9" wide wheel, the tire was rubbibg the strut. Again using a different backspacing would have the set sticking out too far

ROH Drift R 17x8 w/ 245/45/17 - 47lbs
ROH Drift R 17x9 w/275/40/17 - 49lbs

Rear:
275/40/17 fit no problems on a 17x9" wheel
These stick out just a little more than the factory tires, but I think they still look great!

Recommendation for 17" wheels: Use your factory tires and and put them on 17x8" custom wheels or 17x8" wheel front w/ 245/45/17 tires and 17x9" wheel rear w/ 275/40/17 tires

Personally I would just reuse the factory tires and put 17x8" wheels at all four corners. This will be cheaper to do and looks good.

18's
By far the best way to go!!

Front:
18x8 w/ a 245/40/18 tire - fit is perfect
18x8.5 w/ 255/40/18 - again sticks out too far

Rear:
18x9 w/ a 275/35/18 tire - fit is perfect

Recommendation for 18" wheels: Without a doubt the best set is 18x8 up front with 245/45/18 matched with 18x9 out back w/ 275/35/18. This set looks great, fits porportionally and lets you pick up some width out back. The ride quality is also great. Or use 18x8 and 245/40/18 at all four corners.

ROH Drift R 18x8 w/ a 245/40/18 tire - 49lbs
ROH Drift R 18x9 w/ a 275/35/18 tire - 51lbs

19's

Front
245/35/19 on a 19x8" wheel

Rear
275/30/19 on a 19x9" wheel

Recommendation for 19" wheels: GO BACK TO 18"!! While the look great on the car the ride quality is horrible. If you could care less about feeling every bump in the road and want all the look, these are for you. If you just gotta have them then use 19x8 w/ 245/35/19 front and 19x9 w/ 275/35/19 rear or the 19x9 w/ 245/35/19 all the way around.

I have some pics from the fitting I just need to get them off of my disc. I'll get some pics of my Goat with the set up I'm going with and personally recommend,
18x8 w/ 245/4018 front and 18x9 w/ 275/35/18 rear. If I'd been working at Pontiac this is what I would have sold the car with!!

By the way, anyone interested in ROH or other custom wheels contact me I now have pricing and availability info!!

More info coming soon, car is at Baer brakes today!!!

Any rubbing under hard cornering with the 275's in the rear? Also post some pics.

Howie claims no. Pictures will be forthcoming, but his car is whored out to EVERY aftermarket provider in his area.
