Later this year I'll be putting in an order for another G63. I can't seem to find the tire sizes/specifications for the 21" and 22" wheels anywhere. Can anybody point me in the right direction?

I've been pretty happy with the 20" wheels on my current vehicle (I am on my 2nd set of Yokohama Geolanders trying to figure out what's available I think MB is shipping them with Scorpian road tires unless I specify the trail option which means 20" wheels?).

Thanks for any help!
