    you might call a good tire and wheel company. they should have all the specs on the g8gt. i would think it is not the height that matters but how wide. The width is what we deal with on our gto's...

    Are you going to put larger diameter rubber on the wheel or the same diameter (just lower profile)? I live in New Hampshire and I heard a state inspection guy say one time that you cannot change the overall tire diameter and still pass inspection (I suppose unless you recalibrate your speedometer and odometer)

    Yes you can easily fit a 20 with a max of 245 on the front and going from a 19 to a 20inch wheel only changes your speedo by 2% and tell the inspector that the car came with 20 inch wheels its not like your driving a minivan..
