Trying to accumulate some tire information for the 2011 Cayenne:

18 size is 255/55/18, 19 is 265/50/19. 20 is 275/45/20 (in general). (info on Tirerack is not correct.)

For those who have their 2011 Cayenne, could you share what tires you have (either summer or all-season)?

On Tirerack, 18" has a good selection of both summer and winter tires; although all-season selection is limited, at least the well rated Continental ExtremeContact DWS is available.

19" however has very limited selections of winter (no performance winter) and all season tires (no high performance).

20" gets a good selections of tires to choose from, including Michelin Pilot Sport PS2.

The 18" winter tire/whee/TPMS package, with Michelin Latitude Alpin HP tires and OZ Canyon wheels comes out to be about $2,724.

 

Also, for the collapsible spare tire, I guess if you get 20" wheels, you lose that option?

also, is the 19" spare stored at the same location as the 18" spare?
