They’ll fit but for it to be a true square set up, the offsets needed would mean some pretty good poke on the rear

First two are 19x10.5 +30 on the front with -1.3 degrees of camber. Last two are 19x10.5 +30 on the rear with -1.7 degrees of camber. These are on a non pp ‘15 gt. If you’re looking to do 285/35/20 all around, I’d probably stick with a 20x10 + 35 if you can find them

Your ride looks great! what are the tire specs? I'm hoping to avoid tire stretch like what you have those as I like a more flat look.

Also I just realized, PP2 look pretty great without being "true square" Does anyone know the PP2 offsets?
Thank you sir. Tires are Michelin Pilot super sports in 295/35 on the front and 305/35 on the rear. PP2 wheel offsets are +24 and +48 respectively

That offset says to me that you cold do a rotate-able square setup with a pretty big spacer at one one end of the car.

Okay interesting. If i was going to go 20x10.5 285/35/20, would that mean I would get much more tire stretch? I'm not sure if going larger rims, does it correlates to tires stretching?

Thanks!
Wheel width is what affects the “stretch” of the tire. But all tires are different, so the tire brand and size will have an affect on it as well. Michelin Pilot super sports have a large rim protector so the stretch seems more aggressive than it really is. The general consensus is that a 285 is a bit small for a 10.5” wheel but I’ve seen a 285 Bridgestone Potenza mounted on an 11” wheel and it fit quite nicely. Unfortunately, all tires are not created equal

This thread got me to thinking, what is the largest tire I could safely run on my stock Foundry 20X9 wheels?

If you want a 285 tire, and dont want it stretched, put it on a 10” wheel. 10.5 will stretch it a little (mp4s look even more stretched because of the tire’s rim protector), and 285 on an 11” wheel is very stretched (I’ve done it)

295 is typically the best fit for a 10.5” wheel. 10.5 with a 295 is tricky to do square without biting the bullet and running extended front studs and spacers. If you’re willing to run slip on spacers and extended studs and a little more than stock camber you can go as wide as a 305 on an 11. I think there is one offset for a 295/10.5 which works ok, but it will poke a little on the rear if you don’t run a bunch of camber (IIRC)

Depends on the tire. Tire specs will say what the minimum width wheel is for that specific model. Typically a 255 is square, 265 is ok, and a 275 is the limit if you like the bulged look. Autocrossers will run some 285s on 19x9” wheels, but they’re a little weird in the head, and that might not work at all on those 20s.

The factory tires are 265-35-20 and I was thinking of going to 275-35-20 because in the Conti EC DWS06 the larger tire is actually almost $100 a tire cheaper with the same performance specs.

Would you say I should run 20x10 all around in 285/35/20? I'm trying to run a setup without any spacers or any other adjustment pieces.
Yes. 20 x 10 with +35 offset should work. No sense in using a 10.5 inch wheel for those tires when they fit better on 10s.

Yeah a 10” ET35 wheel with a 285 is a good square combo. I’d have to check if the 35 aspect ratio is correct, but that sounds right.

I've seen a few cars with that setup. It seems like 275/35 or 285/30 is more common with the 20" wheel though
