I saw a 2006 GTO with 27540ZR19 Nitto Extremes plus 19 x ? PIAA wheels out back. Offset unknown, too -- as the dealer did everything and this guy just wrote a check.

The fenders were not rolled and the owner swore the only time he rubbed anything was when his two teenage kids were in the back. Wouldn't have believed it if I hadn't saw it with my own eyes.

I'm still REALLY interested in how these fit and if there are any strut or fender rub problems. I'm strongly considering ADR 17 x 8.5 with the stock 245/45 tires... if i can verify they'll fit w/ no issues.
no fender rub that i can tell. i cut the wheel hard to the left and hard to the right and no scrubing there. i have to wait and get some folks in the back seat to see if any rubbing there. so far no problems:cheers hope this help ya

Well 38mm means the wheels are farther away from the struts and inner wheel well and closer to the fender lip. If you're not rubbing on the outer fender lip then it seems this wheel size / offset combination will work well. Any pics of them on the car? What tires and size tires are you using?

THANKS FOR KEEPING US UPDATED!

I'm guessing the lower offset is what allows you to use a 245 width on an 18" wheel. The stock 18" wheels use a 235 width to minimize rub. This is all very good news since ADR offers some great looking low cost chrome wheels. I'm looking at 17" or 18" ADR M Classics in chrome. The 17"s are a 40mm offset putting them slightly closer to the struts/inner wheel well than the 18"s but still farther away than stock. I'll probably go w/ 17"s since my stock tires only have about 800 miles on them (replaced by dealership as part of the certified used car program).

While we are on the tire wheel subject what is the widest tire that the goat can fit under the rear with 17 and 18 I know the thread pattern is 5x120 but I was thinking maybe 18's out back and 17 up front or do you guys think that I should get one rim size I just want some nice meaty tires in the back.
