Agree that the 18s look pretty decent, will be getting a set with snows for winter driving while using the 19s during the other 8 months of the year.

better traction on the 18 inch snows - good choice

btw - for anyone with a cayenne going to a panamera - i can confirm that unlike the the cayenne which essentially has no rear window view in a snow storm - snow vortexes at the back so badly it clogs in minutes - the panamera has no such problem. i don't think a rear wiper is really even necessary for winter.
