A few have put 20s on, not sure on tire size though. As long as total hight of the tire is about stock high you can run any size up to that. You should be able to run a 245 wide tire with out problems. 255 might or might not rub depending on wheel offset. This site will help you determine how each tire compares to others.

thanks i wanna try for some 20'* but i like the 18" Chrome GXP'* rims (or non chrome too)

Aftermarket rims might be cheaper than good gxp'* I can't imagine any of us with them would let them go cheap. Have you thought about ssei or sle wheels? Theyre only 17s but still look nice

Yep, the last time I checked (several years ago) GM wanted $800 a piece for them. I use to see them on ebay now and then for 700-800 a full set, but that was then.

Gxp rims look sick

you can put 22 on with a 2 inch lift, in a lil cuting

thats sick i aint gonna lie!!

20 inch rims will fit no problem with 245/30 tires.
