...If you want a staggered setup, use 255/40R18 for the Rear. The only snow tire in 265/40 is a Pirelli that will not be here until late October/early November. A little narrower will help in snow anyway. Front can be 245 or 235/40R18.
I have the 235/40R18 and 255/40R18 on my E92 (Dunlop Wintersport 3Ds), and it is riding what seems like an inch or more lower, and my speedometer, pretty close on the ZCP wheels & Conti tires, is now 4mph off at 65mph.
If one were to believe that actually lowering the car for winter is probably non-ideal, how would one adjust this package to get back to decent clearance for winter?
