Square Wheel Setup With Different Front/Rear Offsets?

[MustangMan43]

I have a 2021 base GT and I ordered a set of 19 x 10 wheels to do a square setup with 275/40/19 tires all around.

The front offset is +35, while the rear offset is +40. I was expecting the offset to be the same all around, but the manufacturer stated that the front needed +35 to clear the brakes and the rear needed +40 to tuck into the fender.

This is my first set of wheels so I wanted to make sure that sounded right before I mount them. I'm also wondering the following:
- Will the fronts poke out noticeably compared to the rear with the 5mm offset difference?
- Will I still be able to rotate my tires front to rear with the different wheel offsets?
- Any other cons to having different offsets between front and rear with the same wheel size?

Thanks for any help I'm pretty new to all of this!


Edit:
Just to clarify - when I ordered the wheels I said I wanted either +35 OR +40 all around, whichever one worked best fitment wise.

When they got delivered I noticed two of them had +35mm and the other two had +40mm offset. The manufacturer stated that they did this because the front needed +35 to clear the brakes and the rear needed +40 to tuck into the fender.

Trying to figure out at this point if I should just try to return the +40mm offset wheels and exchange them for +35mm offset so it's the same all around.

I am running a square 19 x 10" setup from LMR. Offset is I believe +35 all around. I have no issues running either the 275/40's or 285/35's on all 4 corners.

No.
No.
You have to remember which rim went on front, which went on rear if you are the type of guy to bring rims and tires to the store to mount. If you get directional tires, you can't swap side to side either.

Another option you could do is get a spacer to make the rims the same offset. At 5mm, you shouldn't need a spacer, but don't quote me on that one as I put new studs on immediately so I could run a 28 mm spacer.

Do the same offset all the way around. Not sure where you saw you need to run different offsets front and rear, but for a 19x10 setup that’s false info if you’re running a +35 offset. I run SVE (LMR) 20x10 +35 all 4 corners with 285/35r20 tires. No poke, no fitment issues and I can rotate all 4 corners.

We've seen successful square setups with 35 all around, and also with 40 all around from a multitude of manufacturers.

If they (assuming the manufacturer) says you need 35 front to clear the brakes and 40 won't cut it, then running 35 all around should be fine.

10" ET35 generally always clears the rear fender if you have typical camber and typical tires, but yes its close. Close, but works.

Pics of my setup, stock suspension if you’re a visual person like I am. Lots of pics for 19” in the aftermarket wheel pictures thread too.

19x10, +35, square is a common setup that works. Simply bolt the wheels on. No mods required. These dimensions also allow for rotation of the tires, front-to-back (if directional) and cross (if non-directional tires).

I have not tried a +40 on the front. 19x10, +35 leaves about a thumb-width of clearance to the suspension in the front.

A +35 in the rear fits well and leaves plenty of space to the suspension.

I'd just stick with the setup I noted in the first paragraph, while using 285/35/19 tires.

Thanks all!

Are rims same width? Look on backside of spokes to find rim measurements. Should be 19 “ 10” on all four. If so, no reason to have different offset.

19 x 10” on all four.

Yeah all four are 19 x 10.

I guess I would prefer to have +35 around but then I'd have to deal with exchanging them and waiting for them when it took a little over a month for them to get delivered to begin with.

I might just stick with this set and put the +40 in the rear. The only downsides I have to that now are it might be tougher to sell the set if I decide to switch them in the future, and I also can only rotate my tires on the same axle unless I get a pair of 5mm spacers.

There's no performance or appearance advantage having a +35 front/+40 rear offset.

I'd pause, return/exchange the two 40s for 35s. The wait will be worth it in the long-term.

Well with a 10x19 wheel, I would run 285/35 tires, not 275. And with the 35 front and 40 rear offests, running 285/35 all the way around is perfect. The only problem is that you can't rotate front to back or back to front

Ug thats annoying and basically defeats one of the main drivers for square setup for me-easy tire rotations.

I would have returned those wheels and got different ones. What wheel did you buy?
