Suspected cause · Original poster
What I initially thought were scratches and scuffs turned out to be primarily old, hard grease.
Leading evidence: 'primarily old, hard grease' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'primarily old, hard grease' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Check offset' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suggestion
You might want to check the offset and make sure they are for a narrowbody..

Suggestion
I wouldn't run 11" wide wheels in the winter, especially on a narrow body..

Doubt I will even need to run any negative camber up front.

I have Potenzas on now, and they run pretty well after warmed up in 35-40 degree weather, but I want to drive on some lower temperature days to come, and maybe take a road trip over the holidays where weather will be less predictable.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Looking at what appears to be a decent deal for some winter rims and tires for my 40AE. I have Potenzas on now, and they run pretty well after warmed up in 35-40 degree weather, but I want to drive on some lower temperature days to come, and maybe take a road trip over the holidays where weather will be less predictable.
Rim brand is not listed in the ad, and there are no center caps or lug nuts included. Tires are Nokian WRs.
Sizes are listed as follows:
235/40 R18
295/35 R18
Should fit, right?
Good call. They look to be good, but checking is smart. Price is crazy low. Seller just sent a follow up to an earlier question. These are BBS rims. He�s checking offset. About an hour and a half from my house so need to be sure.
These look like the same 997 rims to me, and the offset looks to be out of spec for the 996. Thoughts?

Thanks! I believe these are Carrera III wheels for the wide-body 997. Found this thread, which fits the same rims to a 996 with spacers up front and back.

Doubt I will even need to run any negative camber up front. Even with some scratches and rash, I think $500 is a steal for this winter set.
Found this while searching. Another guy was coming at 1 so I took the gamble based on the no rubbing claims in the post linked below, the price, and the likelihood I can sell them in less than a week if there are issues with fitting them on the 40:

Offset on the 11 inch rear is +51.
Generally speaking you should run narrower wheels and tires in the winter and the smallest rim you can get away with. I believe 7"/9" x 17 will go on a 996. I wouldn't run 11" wide wheels in the winter, especially on a narrow body..
I�ve seen people say that but I think I will be okay considering the difference between a wide body and a NB is only between 1.5 and 3 inches in the rear (996 and 997, respectively I think). I don�t plan on using it in snow, I have a Land Cruiser for that. I�m more concerned about tire temp and grip on lower temperature dry days. Anyone else think it�s a bad idea?
OEM center caps, spacers, if required, and mounting will come in at about $500. Puts me at a thousand all in. Unless I�m putting my health or the mechanical integrity of the car at risk, 1k all in is a good pilot price I think. Would love to hear others� thoughts for or against.
The benefit of running narrow tires is to cut down to a solid surface rather than riding on top of the snow. If the goal is to have a car that can be driven in deep, soft snow, go narrow.
If the goal is to drive in cold but otherwise snow free or compact snow, go wide.
Those will fit a NB car I have a 11.5" rear with 51 offset and 305 width tires on mine. For your intended use they sound perfect. Not sure why you would need to spend any money bolt them on and transfer your center caps over and your set. Spacers will only push them out farther and not needed.
That is exactly the goal! Thank you. If I get caught somewhere in a snow storm I will take the necessary precautions.
Excellent! I appreciate you chiming in. I was thinking maybe about getting them balanced and tested for true round, but I guess I can start with an *** test first. Also though about 7mm spacers up front to get the track back to stock +50 (if I’m understanding offset correctly, but 7mm is only a 1/4 inch). My OE rims are polished, so the caps don’t match. I think Suncoast has the non-colored set for $150 or so. And, geez, the color on your car is majestic.
Hey, Balefire!
I just saw this post about your 997 Classic III winter setup you ran and sold and was wondering if you had to do anything special for the rear 18x11's?
https://rennlist.com/forums/997-foru...now-tires.html
If you had issues or didn't like the setup on the 40AE, I would rather flip these in the 997 forum now before I drop money on center caps, 7mm spacers, nuts, wheel locks, etc. I tried to PM you but your box is full.
Any info on issues, setup (if any), or ride in winter conditions would be greatly appreciated!
The width on winter tires is better if they are narrow but all these tires are wide so I bet the difference is not so great. I also suspect that Porsche originally spec'd narrower tires in order to allow chains.
Before you buy genuine center caps, you can check out EBay. I have these and they have fit and held up fine. Mine were from a different seller but here is one current listing.

Thanks. I took a look but since they're coming from China it will take a month, maybe 2, to arrive. I'm trying to take a holiday trip this month, so I picked up a pair of near mint OEM caps on Ebay and a pair of 15mm Otis Inc. spacers for the front to bring them out closer to the fender to match the rears. It should only be about 8mm past stock.
I brought the rims in the house and damn they cleaned up well. What I initially thought were scratches and scuffs turned out to be primarily old, hard grease. One rear has a scratch and a scuff and one front rim has some actual scratches and scuffs. Nothing to bad, and nothing I can't get fixed if I decide to run these instead of the polished rims after the winter to preserve those:
Absolutely! It's crazy, because I looked at the Craigslist listing at least a half a dozen times since August, and never called for more info. I wonder how many 911 owners did the same since the ad only said the rims "came off of a Porsche," and dude didn't bother to post pics or identifying info, or clean them up.
Caps and spacers arrive tomorrow so I should have them mounted by the weekend. Pics coming soon!
Longer bolts come with the spacers, and seem to be of suitable quality according to what I've read from satisfied customers in the blogosphere.
Caps look like new and fit like a glove. Spacers came, too. Can't wait to see what the stance looks like.
Finally got around to snapping a few pics. Nothing fancy or scenic, but you get the picture. A few impressions:
1. The tail gets as loose as a pastor’s daughter in the snow.
2. These Nokian tires take a while to warm up. Went to make a semi-aggressive pass on the highway at about 65 mph and broke the rear loose. This was after about 10 mins of highway driving.
3. Couldn’t be more pleased with the purchase. These Classic III's look like they came stock with the car.
Side note: Has anyone who runs their 996 at cold temps noticed that it runs a few degrees hotter? Up until this winter, my car has held 180 like Swiss clockwork. Running a few degrees hotter it seems (see last pic).
This is a source reference. Confirm exact model applicability in the original material.
