Default 295/305 winter tires work well on rear of 991.2 in snow?

For those who have either 295 or 305 winter tires on the rear of their 991.2, do they work well in snow?

God bless,
TT

Narrow tires are better in snow

I've seen a couple threads debating winter tire setups. It seems the consensus is that 295 is the "go-to" if you are running a 11 or 11.5" rear wheel. The 12" GTS/GT3 wheels create a bit of an issue.

The 295 width rear tires recommended by Porsche work fine in snow. I’ve never seen a winter tire in a 305 width.

Agreed but the winter set Porsche recommends uses 295s on the rear.

Thanks so much, Dennis. This seems a good recommendation, considering where you live!

I believe in this thread https://rennlist.com/forums/991/1024...ter-tires.html some GTS owners have successfully used 295s on the rear with their 12" wheels.

No problem. I’d still rather drive my wife’s Audi with Nokian Hakkapeliitta winter tires in snowy conditions, but the Porsche is fine with 295 width rear winter tires. Ground clearance is the biggest concern when driving a Porsche in snow. For what it’s worth, I used to live in Indiana. At that time, my Porsche 996 C4S was my daily driver. I ran the sizes recommended by a Porsche, which included 265 width rear winter tires, and it performed well. I haven’t noticed much difference with the 295s. The 911 has considerable weight over the back wheels, and this helps with traction.

Thanks again, Dennis. My only remaining concern is lack of a limited slip diff on my base 991.2 Carrera. Hopefully not a problem. I have Hakka R3s on my 2016 BMW M5. 255s all around. They do a great job.

God bless,

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. .

thats why I get Winter Performance tires, 305 or 295 won’t make a difference, its the compound that makes a difference.

The only concern should be wheel offset and Diamter if changing wheel size.

Yes, one has to consider how much snow one will encounter during the winter. I've heard that the Porsche recommended winter rear 295s work well both in snow and when it's dry.

I use Pirelli Winter 240 Sottozeros II snow tires on my 991.2 in the winter in Golden, CO. So far they have worked very well, with similar ride and noise level to the stock Yokohama Advans in the dry (I have a base Carrera) and plenty of snow traction. They're not even half bad on ice. The Pirellis are the same sizes as the summer tires:F: 235/40-19R: 295/35-19
