Can you put 17" Cup rims on the 997 equiped with 19" tires? I still have my snow tires from my 993... The dealer says maybe, but where can I confirm this.

Anybody else running with 17" tires?

On the 997 (non S) YES since it's brakes are the same size as the 996.

On the 997S NO the brakes are too large for 17" rim clearance

17" on a 997, it might look like a Cayenne.

This happens to be the solution my dealer is now investigating so that I can get snow shoes on my 997...but, I'm worried about going from 19" dpwn to 17" er's. Other opinions obviously welcomed. TIA.

My experience with respect to this comes with my M3. OEM is 18 or 19" wheels and tires. The suggested winter set up is 17". I have 17" snows on right now (225/50-17). Not a problem whatsoever. Understand, I interpret your question with respect to the "ride", and not the brake clearance issue. If you wonder what it's like to go from 19 to 17, it's fine. Ironically, with the 17s it's the smoothest ride going (of course you give up cornering for ride comfort).

I was mainly concerned with the possible changes in the handling dynamics of the car--Porsche suspension engineers specifically set this car up for 18 and 19 inch wheels...I'm sure you know about all this...therefore, worries do set in when talk of 17"er's arises. Maybe I need to just relax--they are just winter shoes--I'm not tracking the car with them on, right? I realize that with the taller aspect ratio, the ride is better..and the cornering/steering response is sloppier. Just don't want the car to be--off--with the 17's.

Things I read here and at other Porsche sites said the 996 and 997 were designed for 18s. At a late date, marketing said "people want 19s for today's bling-factor" (yes, I'm editorializing) so they had to modify some parts and pieces to accommodate 19s. I'm not an engineer, but as I understand it the only things we need to worry about are brake clearance and possibly tire diameter to keep the speedo accurate. If you run 25" diameter tires, shouldn't matter if they are on 17, 18, or 19" wheels. I've been running 17 snows for 3 years now (snowing right now) - on a car designed for 18 or 19 oem.

Appreciate your comments--I guess as long as the diameter is kept the same and the offset of the wheel accomodates the brake components--all should be good. Wish Porsche would have made sure that winter shoes were available for OEM 18 and 19's before the official launch of the 997.

Reviving this old thread trying to get the same answer. Are 996 17" wheels with snows OK to use on 997.1 C2?

Even if they are (and I don't know), why wouldn't you use 18s? There are plenty of them available, lots of tire choices, and they seem to work just fine for my 997S with winter tires, daily driver 10-15k miles per winter.

correct

Fellow rennlister has a set of 17" 996 rims with snows with good tread left for $375. If you see something similar or better in 18" let me know.
