What is the Widest tire on a 2015 mustang I can run?

I will have 325s on some 19x11.5s soon. I will be running a small spacer to get the offset correct.

PIKES50: What does it run..Doing a setup like yours next week...

Where did you get your wheels from?
Also could you fit a 315 or even 335 with those same wheels?

Anyone widened the rear 20" Foundry wheels to fit 315 or 335s?

I'm running a 315 on the back, I have stock suspension and a base model I'm probably gonna go down to a 19 inch rim and try a 345...I know some of the 03-04 cobra crowd ran those

We got 325/30/19 comfortably on the rears
and even shoehorned a 345/30/19 in there as well



Tight fit and no rub!

325/ 30 r19 fit out back with sportline drop and 11" forgestars?

Does anyone have any comments/experience with the SVE GT350 replica wheels in the 20x10 size? There does not seem to be much uptake in these wheels, but to my eye they come closest to the OEM GT350 wheels (the original OEM GT350 wheels are very expensive at ~$1,000 apiece, and are staggered as well).

The SVE specs list the wheels as:

Size: 20x10
Backspace: 7.07"
Offset: +40mm

My 2017 GT currently has the factory optional 20-inch Foundry wheels running 265/35R/20 Goodyear Eagle's on all 4 tires. I was toying with changing them out to the OEM GT350 wheels, but at ~4,000 for the wheels that is more than I am willing to pay - hence my question on the SVE replica wheels.

Lastly, what size tire would be suggested for front and back on the SVE 20x10 wheels?

Thank you for any comments/experience.

Hey guys, new to mustangs. Just got a 2015 Mustang GT. Lowered on eibach sportlines. I want a square setup with 285s all around. I need to get new 19" rims as the stock are only 8.5" wide. I need specifics on rims size and most importantly the offset you guys are using. I want the wheels to be flush with minimal wheel poke as the fender will be on that rim on every bump. What's the rims size and offset you guys are using and what tires? I want summer as this is my weekend all giggles ass hauler.. Much appreciated on the help.. looking forward to joining the 'stang community.

Anyone know if offsets from a 2014 GT500 would work on a 2017 GT? I have a wheel/tire set - iForged Classic 3 piece forged wheels, 20x11 rears, 20x9.5 fronts, mounted with Michelin MPSS tires, K2 series (the wide ones) 315/35ZR20 rears, 275/35ZR20 fronts. They are off my 2014 GT500. I have a friend with a 2017 GT and we are wondering if they will fit (we are not in the same state so just trying them is not the easiest option) . I think the offsets are pretty close to what I have seen quoted here but anyone have direct experience?

Red Turtle is your car lowered at all?

I run the 19x9.5 wheels from my 11 shelby on my 17 5.0 In winter with some dws tires without issue. The front brakes are pretty close and I have a base car. If he has a PP car with bigger brakes probably not. If it's a base car like mine he should be good.
