This offset is fine. The diameter of the tire you picked is way too large.

well i was gonna go drag pack in the rear with a 17x10 but i found a set of 20x11’s i like i just want it to look good and fit perfect at the same time. i don’t want the tire to be too small and have to buy new tires. so for 11 wide ima have to go with something like a 315/35r20?

Yes 11 inch rim should do a 305 or 315 depending on the tire Mfg.
Rims in inches, tire width in mm, height is % of width.
35 a tad better than 30 in terms of sidewall
315 * 35 = 110.25 = 4.3 inches (about 2 & 3/8 inches from rim to ground)
315 * 30 = 94.5 = 3.7 inches (about 1 & 9/16 from rim to ground)

everyone said that tire size would be way too big

Really? How come? Is the GT different size wheel well than GT500 or other variants?

Plug in the stock size and what you’re contemplating here. You don’t want to be more than 3% larger or smaller than stock diameter

OP what is the stock size?
Depending on height you may have to tune the speedo for the new diameter. A taller tire will also decrease your gear ratio a tad, so the speedo will read slower

Stock diameter for GT is ~27" (depending on exact version). This is 28.7" (which I mentioned earlier). It's not even the speedo, this tire is more like truck tire.

so would 315/30r19 look weird with being a low profile tire on a stock height s550?

I once ran 19/11 305's with steeda minimum drop springs and it looked good.

I ran the exact set up on my 2014. I dont think this looks like a truck tire. Am I missing something?

you were running a 315/35r20?

 

[NJMike]

you were running a 315/35r20?

Yes that is what you see there. The rear had a 1.5 inch drop

so you think i would be good running that on stock height?

 

[deolane]

i ran a 20x10.5 with a 295/30r20 the tire was too low pro but fit just fine
