Currently have the stock 19" staggered setup on my 2015 GT with/Brembo/performance pack.

Going with:

Front Wheels: 20" x 9", Backspacing 6.26", Offset +32mm, Tires: 275/35/20
Rear Wheels: 20" x 10.5", Backspacing 7.52", Offset +45, Tires: 295/35/20.

I'm ok with the new setup, but was recommended to go with 255/35/20 in the fronts. However, I think the 275 would look much better and fill in the fender a bit, and match the rear somewhat too.

Car is lowered only 1" on the Steeda Sports springs.

Should I stick with the 255 for the fronts or should the 275 be ok?
Anyone on the forums have this setup?
I did a search and do not see many.

Hello. by the numbers it looks like it will work just fine.
275 ser on the 20x9 is no big deal and possibly better then the 255, the 295 for the 10.5 also works perfectly is right on the dot.

I have the same dimensions but run the 255/275, fenders fill fine but then again I am kind of low. I wanted to get a little more aggressive just not for looks but running a tire that's a little wide helps protect the rim of your wheel so that's a benifit as well for your sizing. I'll go wider on my next set. I just replaced all my tires with NT555 G2.

That size will work just fine. We run that set up a lot. Below are a few pictures of a ruby red mustang lowered on eibach springs on 20x9 +32 275/35/20 and a 20x10.5 +45 295/35/20. No rubbing issues at all and the 275/35/20 looks perfect with springs in my opinion.

Thank you. And yes protecting the rim is a good thing.

And that is the exact wheels and tire sizes that I'm going with, but in the matte black setup!

That size will work just fine. We run that set up a lot. Below are a few pictures of a ruby red mustang lowered on eibach springs on 20x9 +32 275/35/20 and a 20x10.5 +45 295/35/20. No rubbing issues at all and the 275/35/20 looks perfect with springs in my opinion.

The fitment will work spot on, tire sizing you can do either or without issues.

I really like the look, although after seeing how the rear looks with the edge of the rim sticking out past the tire, I would have preferred 305 instead of 295. The rim sticks out past the rubber of the tire, which is exactly what I did not want.

Any issues with the 275/35 tire on the 20x9 wheel?
