greetings all.

Hello all, I am in desperate need of knowledge/info.

I have a 335 GT xdrive, i have bought the e90 M wheels to replace the stock rims not knowing about staggered rims going to mess up transfer case.

wheel specs 19x9.5 for front, and 19x8.5 for the rear

anyway, i am trying to figure out what size tires i can fit my wheels. i am currently running 245/35/19 for the front, and 265/35/19 for the rear.

Can i just switch out the rear to a different tire size? if so what can i get?

please and thanks in advance!

19 x 9.5 front and 19 x 8.5 rear doesn’t make sense. Exactly what style of wheels did you buy? Staggered wheels in and of themselves don’t cause a problem with xDrive. The tires need to be the right size. It’s unlikely you can just swap the rear tires.

Hello, I purchased the E90, E93 M3 220 Style Rims. I am looking for the right tire size combo I can swap out the current ones on it now.

rim style 220 has ET29 front, which is a bit low and ET23 rear, which is a LOT low, will poke a lot and not really good for an F34.

the tire size combo i suggest for your F34 xdrive with those offsets is 225/45/19(27.1") front, 255/40/19(27.0") rear. this is primarily to minimize the amount of poke you're going to have at the rear.

245/40/19(26.7")+275/35/19(26.6") rear is another option however there will be a decent amount of outside tire tread poking.

not sure if you care about handling but fwiw, there is understeer associated with a 30mm front/rear tire width stagger. ET23 at the rear will cause even more(understeer).

Additional to ^^^^^:

OEM staggered set-up on GT (like I have), with the tires as 1st option recommended to you by @alohasurftoad:
Front: 19 x 8, +30, 225/45/19
Rear: 19 x 9, +42, 255/40/19

However, I run with spacers on my GT, 10/12 mm. That makes the actual offsets to be:
Front: +20
Rear: +30

It is possible to use staggered E90 rims on F cars, I've done that on wife's F30 with 225Ms:
Front: 19 x 8, +37 (original offset)
Rear: 19 x 9, +39 (original offset)

I've had rears offset modified to be +47 by having the landings on the wheel hubs machined (8 mm of material removal).

There are places that can do similar alteration to the 220s to your likings. I would leave fronts as-is and have rears machined to bring them inwards to minimiza the poke. In any case, I'd try mounting the rims first and only then make a decision to have the rears altered and by how much.

That's how modified 225s look at the rear of F30 mounted:

thanks for this response, its definitely poking out there. now i feel i should have just stayed with a square set up.

Use this online tool. It is pretty accurate:

If finding a shop to remove at least 7 mm off the hubs of the rear rims (effective offset would become +30 like on mine) is a problem, you might consider selling the rims as-is (if you not 100% sure you like the looks).

Even if you manage the offset adjustment, keep in mind that tires will be ever so slightly stretched (the 255 section).

Also, if you plan/have the car to be aggressively dropped, you could have rubbing issues.

GTs came with staggered set-up in M Spec package from factory (and I love the look of mine with spacers), it's just you happened to choose the rims with significant offset difference when compared to OEM fitment.

I have 9 in the front 10.5 inch in the back 20s and it works perfect fine

This is my set up

Would help if you listed the full specs for your set-up: tires (width/side wall and offsets on the rims (front and rear).

Your ride height looks different... I have much smaller wheel arch gaps than yours while riding on 19" OEM staggered rims. What kind of suspension do you have? I can see XDrive batch on the back... So either Xdrive or Adaptive XDrive, right?
