Thanks for posting your setup!!, most likely I'll be doing the same thing when I get my wheels, thanks

i have the morr v8.2 20s... and i used 255/35/20 285/30/20 standard setup and its great. not sure why you guys want such a narrow tire in the front... bigger size gap will just make the car understeer more.

Alan l. · 05-29-2012, 03:58 PM

^^ its because of the Xdrive system. 245/285 has a identical rolling diameter for the front and rear tires which is important for the AWD system.

If i had a RWD 535 i would have gotten 255 up front for sure.

opps sorry i must have missed xdrive bit

Ftenner · 07-27-2012, 05:28 PM

Sorry i think i had asked this before? I'm about to purchase my tires this week, just want to make sure. So what will be the problem if I buy 255 instead of 245?(fronts) If the rolling diameter has a difference in an AWD, so will this damage anything? Is the difference big enough that may damage anything?

Alan l. · 07-27-2012, 05:57 PM

Nobody knows for sure. All I know is that with xdrive you want the front and rear overall diameter to be the same or as close as possible.

FWIW, Costco will sell these tires, install and balance them, for about $1,300, tax included. Amazing!

While they do not have the Hunter-force balancing machine, they have very new equipment.

Alan l. · 07-27-2012, 09:16 PM

costco carries Michelin PSS??? Damn i paid way more than 1300 at Tirerack!
