Denis, if you do go this route, I do remember one thing told to me by a tire dealer. Go a bit narrower than your standard tire. You want the tire to "bite" into the snow. You also want the very deep tread to fill with snow. The Snow in the tread is what ties to the snow on the ground giving you traction.

You could mount up some tall & skinny KO2’s on that car. They love snow and get great mileage.

Might get a funny look from the P car crowd.

I've had several different brands of snow tires starting with Dunlop when I lived in Germany. BTW in Germany if you don't have snow tires and are in accident during the winter you are per se liable. Or at least that's what I recall.

On my 993 C4 I had Yokohama I believe. Mainly bc that was all i could find in the size.

Blizzaks on my Land Rover Disco 2 and pos Volvo XC90 while in Northern New York. Ran them for 3 seasons and had at least 90% tread remaining

One season we drove from NY to Tennessee in late March. By the time we got to TN the Blizzaks were much louder but that changed once we got back north with the colder temps.

As to other responses:
Yes usually one size smaller
Absolutely no to only using on drive wheels
And far superior to all season due to compound when snows begin to work better at lower temps

I had snows on my E30 M3 and E34 M5 in Germany. My boss tried to explain to everyone that BMWs are horrible in snow. Meanwhile i went wherever I wanted...

Thanks to all! I've never had modern snow tires on a vehicle, probably because I live in SoCal and drive to Mammoth once or twice a year. I've heard the reports that a regular 2WD car w modern snow tires will outperform an AWD w summer tires in the snow...they are that good.

As for the hypothetical question, a friend acquired a 993 C4 from a family member and I might have an opportunity to buy it. The only scenario where that would be a fun car for me is if it was a year-round driver somewhere w winter or for skiing trips. I drove it yesterday on pavement and it doesn't scratch my 911 itch in any way...I'm too spoiled w lighter, quicker cars. With the right mods and a serious diet, (plus snow tires), could be fun in snow, however. :cool:

i mean a 2wd car on all seasons will out perform a AWD car on summer tires. dont even have to go to winters. but yes, winter tires will drive circles around AWD cars in the snow. not only will it not get stuck, but it will turn and brake far far far far far far far far better. it turns out turning and braking are the things that stop you from crashing into things. any 2wd car will be able to turn and stop better than any AWD car if it has winter tires rather than all seasons.

i dont know why youd want a AWD 911 for any reason personally. and esp for winter driving. its pretty much the ideal 2wd car for winter work. id love to get my hands on a stinky 996 for lake racing, probably the only reason id get into a porsche again frankly. stinky 996 with an LSD, snow bars, and studded tires? yes, yes i would like that very much. but im the weirdo who unironically thinks the miata is one of the best winter cars money can buy.
