Hi Everyone, I just purchased a 2009 Cayenne Base for my son. Its in great condition but we want to update the tires and wheels. Currently have 235/65/17 on the car with the stock wheels. We want to upgrade to 19 in wheels but have no idea what will fit. Goal is to purchase off ebay OEM 19 in wheels. Can anyone let me know what size wheel and offset will fit the car. Perhaps the correct wheel serial number? Also any recommendations for tire size? thanks so much.
