I've seen and heard mixed opinions on going with staggered rims/tires on all wheel drive vehicles.

I've seen several Cargraphic wheelsets recommend 265/35-22 F and 315/30-22 R...

265/35-22 is 29.3" tall
315/30-22 is 29.4" tall

Running the rear wheels 0.5% faster than the fronts... is it BAD for the all wheel drive system?

Logic tells me that if the center diff is NOT LOCKED then it's no big deal...

How does the Cayenne AWD system work? Is it a big deal?

 

tell me more... hows the ride with the staggered sizes? No probs with AWD system? Do you use 9.5/10.5's?

 

excellent... soon I'm going to hit you up for

1) front lip spoiler w/foglights
2) V6 backbox w/tips
3) rear valance...

 

Alot easier (or should I say more complete) for tire rotation if all four wheels are the same. Also it makes it easier if you keep an extra tire or two around JIK of a blow (because sometimes larger tires 22s 23s 24s are never really kept in stock)

With staggered your rotation will look like this:http://www.tirerack.com/images/tires...ch/rotate4.gif
Less optimal than these:http://www.tirerack.com/images/tires...ch/rotate1.gif

Sport Technos can be installed 9" on all 4 corners or 9" in the front and 10" in the rear.
Refer to the bottom of this page for P/N and descriptions: So if Porsche equips them that way, it surely is O.K.
