Hi I am currently running the standard 255/55/18 wheel size on my 05 CS.
1- How wide of a tire can I put on without changing these rims?
2- How wide can I go if I get a new set of rims and still stay within Porsche specifications for Cayenne?
TIA,
Sam

Both Michelin and Pirelli, for example, list a 285 tire as suitable for 8-10" wide rims. Your 18" wheels are 8" wide so they would theoretically be ok for that size tire. Your speedo will be off as the 285 is a taller tire; going up one size to a 265 might be a better choice.
On the 2011 Cayenne the widest factory wheels are at 10". I don't know the size of the widest wheels Porsche offered on the Cayenne before that.
