Are there all-season/ winter tires available that will fit on the stock factory rims?
Just trying to decide what to do w/ my factory wheels now, are they worth keeping?
Seem to remember hearing there's no winter tire that will fit but want to make sure......

Andrea,
LOL. This thread has become a monster. All the info is here, you just have to dig for it.
(Off topic, my wife, who shares my love of Italy, got a chuckle looking at your signature line: La vita è troppo corta per non guidare italiano..... We got the basic meaning but what does "guidare" mean?)
Porsche Factory 997 Turbo
8.5x19" 23 lbs. 14 oz.
11x19" 28 lbs. 13 oz.
HRE M40 Monoblok
8.5x19" 21 lbs. 8 oz.
11x19" 24 lbs. 14 oz.
HRE M43 Monoblok
8.5x19" 21 lbs. 8 oz.
11x19" 25 lbs.
Champion 171:
20.1 Front
24.3 Rear
The Champion RG5 is even lighter, very impressively so. But it is not one piece forged AFAIK, and has chrome lips.
As mentioned, I don't have any direct experience, but have read that Magnesium wheel is softer and therefore more easily damaged for street use.Quote:

I believe there are at least 2 choices for you on winter tires, Continental TS810S and Nokian WR. Both have N0 designation for Porsche Approved.
If I remember correctly, W211 here have fitted Nokians on his 997 Turbo last winter and have nothing but praises for them. He made quite a few trips to Whistler on those tires.
Size will be 235/35/19 front and 295/30/19 rear.

I'm not sure if it'd make a difference not to use Porsche approved tires but I like the fact that they've been tested extensively by Porsche engineers and are proven to work well with the car. That's why I'd rather stick with the "N" rated tires even though they're apparently only available through Porsche dealerships. I had to pay $700 more for my new PS2 tires than what they would've been sold for from Tire Rack if they were available there.
A local friend of mine checked to see what tires are available and apparently the Continentals were discontinued last year. This is what he had to say:
"Yes, I purchased Pirelli 240 SZ winter tires (235/35 19 and 295/30 19) - they fit the stock 997 Turbo wheels.
Here's what I learned through Walt at Tirerack (ext. 372):
The Continentals listed last year are being discontinued; although still in stock, if a tire had to be replaced later there's a risk none would be available and I have to replace all tires. Seemed like a reasonable concern.
The Nokian WR is an N0 rated tire; $1,302 for a set (I'm not sure this included delivery).
The Pirelli 240 SZ (Soto zero) is an N1 rated tire; $1,382.28 including delivery in Bellevue."
Now, you have to be VERY careful with those winter tires or any new tires when first mounted. He found that out the hard way a couple weeks ago on a drive with me and Larry. On a sharp corner I was able to negotiate that just fine but he didn't have enough grip and ended up going straight ahead into the cornfield and spinning out. He suffered very minor damages fortunately but that was definitely a lesson learned for him. Those winter tires do not have as much grip as the summer tires.

Should explain everything you need to know about N rating.

Unlikely. However, Manthey wheels are used by 997TTs on the Ring and those cars seem to be doing just fine. Probably just a nice marketing gimmick on behalf of Porsche.

Yeah and I guess the GT3RS wheels used on the GT2 w/ ceramics do just fine too without being ugly like the stock turbo wheels.
