FWIW, I just checked Tire Rack, & it says that those Continentals won�t fit a C4S, & when you select �see what tires fit my car,� all the results are summer or track tires.

I use the Continental Extreme Contact DWS on my 4S with no issues for winter driving.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

I'm looking for winter tires for 2003 C4S. I have stock turbo twists 18x8 fronts and 18x11 rears. Does anyone have a winter tire setup that fits these wheels they recommend.
I've looked at a few threads and I can't seem to find a definitive answer.
You can probably find what you are after by visiting Tire Rack.
Maybe you can help further:
Where do you live? What are your winters like? Can you fit 17" wheels (assuming you will really see a fair amount of snow).
I searched and searched for all-season tires for my C4S, and I kept finding the answer that there aren't any all-season tires that fit the rims and keep the front/rear circumferences within 1%. As a former Chicago resident, I know how what you can face, and I'm guessing that those fat tires on the rear of the C4S won't be very good, regardless of the tread pattern and rubber composition. I think you may need to invest in another set of wheels in order to make your car a year-round vehicle in that climate.
i have the same issue with 4s
Porsche recomends 265/35R18 with 10Jx18 for winter rears. Or 295/30R18 with 11Jx18. Both are expensive.
so I have solved it this way:
225/40ZR18 - 8Jx18
275/35ZR18 - 11Jx18
already 4 winters done
There are a lot of good reasons for going with the smallest diameter wheel you can get to clear the brakes.
If you insist on staying with 18" wheels, it will be a compromise. The only thing I can suggest is to go with Continental DWS 06 "all season" tires. I have these on my car. They're fine for most conditions - but I would not recommend them for severe winter conditions.
For that purpose, I bought a set of Pirelli Sottozeros. There are places that have your (Pirelli) 18" rear tire in stock. Finding fronts may be a problem.
Should you decide to go with 17" wheels your options increase.
So I guess I have not found my answer because there really is no answer without a change in setup or go to all season. I�m not planning on driving in really bad weather, mostly I care about just cold weather and some lighter snows. Maybe in that case the all season will be ok.
I have a set of Dunlop winter sports on turbo twists I bought for my C4S in 2015 I think. I bought them from a Rennlister who had sold his car and had never used them, they still had the stickers on em. I'm running them now and have put them on every winter since I bought them. They are 285/35/18 and 235/40/18. I just recently put my C4S into daily driver status so we'll see how they do as the weather gets worse and colder/snowier. I have a 4*4 truck for the deep nasty stuff. I guess the big question is whether they still make them?
FWIW, I just checked Tire Rack, & it says that those Continentals won�t fit a C4S, & when you select �see what tires fit my car,� all the results are summer or track tires. If anyone finds all-seasons that will work with an AWD widebody 996, please post them.
Tire Rack is full of **** when they say it won't fit. They have their computer and if you ask for something that differs from what the computer says, they say it won't fit.
I'll not bore you with the stories of disagreements I've had with them. Suffice to say, I know how to use a tire calculator and if I know the wheel dimensions that work on the car, I can make my own decision on what fits. I actually got paid to make decisions on tire and wheel selection at a prior job.
Attached is the Porsche approved winter tire guide. Page 10 lists the 996. If I am reading it correctly, 17" wheels can be fitted to the C4S.
Edit: I wasn't reading it right. It looks as though 18" wheels are the only way to go. If I owned one, though, I sure as hell would confirm this.
If you can provide your wheel dimensions and current tires sizes, I'm pretty sure I can find a good set of
winter tires
that will suit your needs. And as a reminder - I always suggest going to the smallest diameter wheel that will ft, when assembling a winter wheel/tire package. There are solid reasons for this.
i ordered Pirelli Scottozero 3 winter tires for my 2003 4s on 11/5 from a hotrod shop, and they are due in anyday now. 225/40/18 and 265/35/18. About a grand all-in, mounted and balanced.
I think I am going with Continental Extreme Contact DWS 06. 225/40/18 on the fronts, and 275/35/18 on the back. They also make 285 and 295's, but I've heard thinner is better in the winter. Should should fit on my current C4S 18" turbo twists. They won't be great snow tires, but I'm not looking to daily this in the snow anyway.
I'm guessing on TireRack they say it does not fit if it's not the exact recommendation from the manufacturer, but I think it should be ok.
Do they not offer 265/35R18 for the rear? That would be even better than 275.
This assumes stock 10" wheel at the rear. Regardless, if you go with the wider tire (275) the diameter will about 0.5 inches larger than the front tire. Not a huge difference, but also not ideal.
The selection of tires for 11x18 wheels shrinks by the day. I got a brand new set of Porsche Sport Technos from the Porsche classic program and ditched my factory sport designs. The Sport Technos, even in narrow body, are 11x18. Discount tire direct was able to order me 295/30/18 rear tires direct from Pirelli but nobody had them in stock, including tire rack.
I use the Continental Extreme Contact DWS on my 4S with no issues for winter driving. I'm in NJ, close to Philly and we do see snow although I've not driven when there has been a major snowfall say over 4" or so.
I have 235/40-18 fronts on my 2003 C4S with no clearance problem. These match 275/35-18 rears near perfectly and both fit on the standard 8 and 11" rims. The Porsche recommended 265/35-18 winter rears are supposed to be on 10" wide rims so they wouldn't be ideal on the 11" rear rims. I went with 285/35-18 rears and have been told by many that this 1.9% difference is fine. I have had them for several years and 6000 miles with no noticeable problem.
Just picked up a 2002 C4S that I plan to daily all year in MN. Coming from an STI, I was surprised by the lack of options for winters. I went with the attached Pirellis. Spendy $$$. I wanted to keep the stock rims for winter and get some aftermarket rims for summer. Hopefully the awd system will work as intended with these sizes...seems great so far.
I went through this several years ago. I like to swap my own summer/winter tires, so bought a used set of 993 Turbo Twists that had been chromed. Got them pretty cheap and they were beautiful. Mounted Blizzak 265's on the 10" rears, and they look pretty stretched, but work fine (I had to get some special spacers due to the different offset to get them out where they looked right). The 265's would not stretch onto stock C4S rears.
Piggy backing here - looking for snows for my 996.2 C2 with Sport Classic II (8.5" F / 10" R).
Does anybody know if the rears would be ok with these sizes (particularly the profile)? Since the width is sized down to 265, I feel like a 40 profile would be ideal?

R 265/40/18

and have so for 7 winters, im on my second set of the Pirellis
theyve performed very well, never let me down
i use 7mm spacers in the front and 19mm spacers in the rear
in the summer i run the turbo twists with Michelin PS2s in 225/40/18 and 295/30/18
