Generally thats right but How often are the roads covered in deep snow? I'm in Toronto and that rarely happens so narrow tires would be a disadvantage on cold dry or wet roads. To gain any real advantage you would have to go to 265 or something I would think and that wouldnt be any good on anything but snow. .
I agree... these days with the climate change we get maybe 4 days a year totally snow covered.
Not to mention that narrow tires would require much narrower than stock wheels. And they're essentially impossible to find, unless you go an expensive three-piece route that hardly makes sense for snow tires.
I had a few outings last winter on my 19" 295 Conti Winter Contacts, including a long morning through a surprise mountain snow storm heading to Santa Fe. No surprises and reasonably stable.

Actually, based on the published specs for the winter wheels and tires that Porsche offers--at least the 20" ones--and using an online offset calculator it appears the front Porsche winter wheels and tires (they're 245s) will fit on the rear just fine (always assuming I did the calculations correctly!), with either a 3mm or 5mm spacer to improve the looks. By the way, thanks for the article about your 911 in your magazine. It helped me decide how best to order mine.
God bless,

I was able to try my brand new C2 in 6" of new snow today. I have the 20" factory winter tire and wheel package with Sottozeros. While the Sottozeros can be very noisy on some pavement they are great in the snow. I had no problems, even without an LSD on the C2.
295 cuts off at 11". 10"-11" is the recommended for a 295. 11.5" you really want to use a 305. They do make a 305 snow tire these days. (they didn't pre 2020)
If you are buying an extra set of rims, go with an 11" rear as that opens up snow tire options. Price delta for the rears 295 vs 395 is about $80 bucks per tire. (as of 4/4/2022 per tire rack)
