I'm picking up a new set of wheels for my 996 C4S. The rears are gonna be 18x12. But the OE tires (Continental Contact 2 in 295/30/18) max out at 11" rim width. The Pirelli P-Zero System goes to 11.5" so I might go that way when the time comes. Anyone know of a decent tire that can mount on a 12" rim within manufacturer specs?

 

i have the same questions as you and same car as a matter of fact. i found that falken fk452 or something make the size 315/25-19, this would be a good fit. hope this help
