I have 265/35R20 tires on my '15 GT. Stock suspension, not going to lower it.

I just bought 2015 style Performance Pack rims from AM and they are 20x10 all around, back spacing is 7.4" and offset is +48mm.

I didn't go to the other option of a 20x8.5 because I wanted to use my tires, they are 265 miles new and wanted the ability to rotate them.

WILL THESE FIT?????

 

They'll fit fine, but they'll be a little stretched. When they wear out, I'd move up to 275s or 285s.

 

Thanks....I'm stressing. Lol


And the rims won't rub any suspension?

 

I can't say for certain because I'm not too familiar with the S550s, but I can't imagine you having any issues. The offset is higher than the S197 rear wheels though, which would tuck them in more. Before you have your tires dismounted, try to mount one of the wheels on the front, with it jacked in the air and turn lock to lock. Hopefully you won't have any issues with the calipers. If anything, you MIGHT need a 1/4" spacer, which is about 6mm. That would essentially make the offset 42mm, which is the same as your stock wheels, just with another inch toward the inside of the car.

The only way to be sure is to try it...and again, just do it with the front wheels only, no tires, with it jacked in the air, before you spend money unmounting the stock tires.

 

I got these too, putting 305's on the rear
