If I did purchase a set of staggered rims for my G37x should I be worried if the fronts are 8.5" and rears are 10"?

Can I put rubber on these that will work? Or will the rim diameter difference alone cause the AWD sensors to go all crazy on me.

Thanks.

I assume you meant rim width rather than diameter, unless the fronts are 18s and the rears are 19s for example. As long as you have offsets that will allow you to run compatible tire sizes they will work ok. One example for 19s would be a 245/40/19 & 285/35/19 set, this results in about 0.5% variance.
Use this calculator whenever trying new combos, for your AWD you want as close to zero variance as possible and no greater than 1% difference.

Brad, you might actually want to link the calculator next time

Thanks Brad yeah meant Rim width, Fronts are 20 x 8.5"
Rears are 20 X 10"

Just want a tire size and rim setup that won't throw off the AWD.

I don't understand why you'd want different sizes on AWD. With AWD on a car that favors RWD, you're going to want to rotate the tires for longevity. What are you hoping to gain, and is it worth replacing tires more frequently?

Good point only I drive so little mileage wise that it wouldn't be a big deal.

On 20s you have two choices that are both a very minimal 0.07% variance.
235/35/20 & 275/30/20 OR 245/35/20 & 285/30/20.

I have the 2nd combo on my RWD G, my offsets are 8.5 +40 and 10 +45. What offsets are offered w/ the wheels you want?

SurreyG

The 8.5 are +32 and 10" are +35.

You'll have to run a narrower combo since the backs are a +35. A 225/35/20 front 265/30/20 rear will fit and only have a 0.23% variance, and the rear is slightly taller (which is ideal since they wear faster so the variance will improve over time).
If you run a 275 in back it will be too close to the fender and may require running heavy camber to clear.
