Are there any 17" wheels that will fit on the 996TT rear axle? There seems th be a lot of clearance around the rear brakes with the OEM 18x11's. I believe there are smoother riding better performing tires for the rear in 17". I was thinking of Goodyear 315/35-17 and 235-245/40-18 fronts.

 

17s would look hideous IMHO

 

Hmmmm. I would have thought there were enough choices in 18. You will experience a substantial reduction in handling in my opinion. If you do decide to take this route, make sure the overall diamter of the tires is close to stock and, more importantly, that the front to rear overall diamters do not vary by more than about .2 inches. The viscous coupling will not be happy if there is too much disparity.

 

Anyone know of a 17 that will fit? There are lots mote tires available. I'd like to try some Goodyears.

 

17" oh my
