Just bought a 2012 GT500 with the SVTperformance pkg. Rears are 20's fronts are 19's.... I'm looking to order a set of wheels and tires for all season and I don't know what widths the rims are... I'm assuming fronts are 8.5 and rears are 10... Is that correct? The standard is a 19 x 8.5.

I'm guessing they are 9.5 wide, front and rear. Earlier years used 19 x 9.5 wheels front and back. Might be wider in the rear. If you pull off a rear wheel, it is probably stamped on the back.

For winter wheels, I'd check American Muscle to see what is the narrowest wheel they have that will clear the brakes. Then put a fairly narrow tire on those wheels.

Thanks for the reply... I actually found it in the GT500 supplement book... They are 9.5 front and rear as you assumed.
Thanks again.
