Tire measurements

Luis_JR · 03-04-2015, 03:46 PM

Can anyone tell me what the measurements for tires are for rims 18x8.5 in the front and 18x9.5 in the rear

Are you asking what comes OEM or do you want recommendations for aftermarket wheels? Let me know and I can help.

I'm asking some what tires fit those wheels, does that clear it up?

As long as the rolling diameter (F to R) is within a certain percentage, you won't have any issues whatsoever. BMW, I believe, was actually the first manufacturer to offer staggered wheel options on an AWD car from the factory. The XDrive system is not as "sensitive" compared to the Audi Haldex or Subaru symmetrical drive systems.

We have set up 100s of Xdrive customers with the same 235/40 | 265/35 setup

And it won't rub?? And if it's not too much trouble, do you think you can find me a picture of how that looks?

Stock (at least non-Xi) is 225/45/18 and 255/40/18, which makes the rears 0.06" taller.

Why not 245/40/18 and 275/35/18 (.14" difference) or better yet, 245/45/18 and 275/40/18 (.02" difference).

The 2nd combo would be more ideal as they are slightly taller than stock, so you it would help correct your speedo slightly as well. I run 245/35/19 and 275/30/19.

8.5 Min. 225. Ideal 235-245. Max. 255.
9.5 Min. 245. Ideal 255-265. Max. 275.

Recommended Fittings only. The tire guys will set you straight.
Cheers.
