Did some research and according to what I read staggered wheels shouldn't be a problem on an AWD coupe. First time changing out wheels on this car. Previous cars Ive owned like an e92 (awd) I ran staggered wheels without a problem.

Im looking into the following:

Lug Pattern 5x114.3
Fronts are 19 x 8.5 offset +43 with 245/45/r19 tires.
Rears are 19 x 9 offset +45 with 275/35/r19 tires

 

your fronts should be 245/40/19

 

Yep, fronts should be 245/40, but an even better combo would be 235/40/19F 265/35/19 rear, that's a better mount in back on a 9" wheel and the front to rear diameter variance is only 0.37%, the 245/275 setup would be 0.52% and the 275 on a 9" is a bit of a pinch mount.
Use this calculator when trying new setups, and being well under 1% variance is ideal.

hmmm. Someone selling them says they were on a g35....Looks like Ill need new tires.

 

Probably on a RWD, if the tires are in good shape just get new front 245/40s and you'll be ok. If tires are in poor shape I'd look for that 235/265 combo first and if the tires you like aren't available in those sizes the 245/40 275/35 set will suffice.

 

thanks waiting to hear back from seller.

 

Update: Heard back from seller, price dropped from $900-$800 then upon inspecting tires hes dropping price to $700 because only about 50% is left.

They are g37 Sport rims powder coated in a gunmetal color.

 

Sounds like a nice deal as long as the wheels aren't all chipped up or curb rashed.

 

problem is he is dropping them off from a distance away.. don't wanna waste his time or mine coming all the way here.

 

I'd have him shoot a clear close pic of each wheel, I wouldn't consider the sale otherwise.

 

I had a M35x and wanted to run staggered wheels on vossens. I talked to vossen they told me DO NOT run different size stagger wheels. That IF I do run stagger I they all need to be the same size specs on all 4 wheels and tires or u might be looking in to issues with the awd system

 

Sale fell through. Found a set of sport rims staggered set running 245/40/19 on all 4. Could this work?

 

No problems running those tires on all four. The 1/2" stagger on those wheels won't change your rolling diameter.

 

Well they were wrong.. and thats surprising. BMW runs staggered wheels on their AWD cars just fine.

You just need to make sure the diameter of the wheel tire combo front and rear are within like .8% of each other.
