I've been driving around New Hampshire with the 20 inch michelin tire package. I drive a lot on backroads and it makes a huge difference. It's so cold, that even if a lot of rain came down, and then froze, I may not be able to make it up my driveway without it.

I use snows on all my cars because it's worth it when you need it and you'll never know when you need it.

The way I looked at it, for $ 5000 I get a new set of tires worth at least $ 1700 and a new set of rims which changes the look of my 991s.

I love driving my car all winter, and it's a long winter up here vs. keeping it in the garage.

 

Wonder if these guys had snow tires ?

4 pages, has anyone mentioned what if the need for emergency braking and swerving is needed??

 

When it is near or below freezing, even dry, all weather or winter rubber compounds will react more favorably than summer rubber compounds. Thats why they are good for you.

PS I was about to shop for the new Michelin AS3 tires after seeing that Randy Pobst lost only about a second a lap around Laguna Seca as compared to Supersports. Their compound would have to be better for cold weather driving than sumer performance tires. But a friend with those on his S6 advises that they don't work in the snow. So real winter snows are needed for snow.

 

Good point. Still better than my late model Buick in dry. Northern VA--3F degrees. Burrrr! Miami, your prodigal son will return.

 

If anyone wants to sell a set of snows after the winter, please let me know! Im really glad I started this thread and really appreciate the discussion and opinions!

 

Regarding stopping.. Start at 45sec.

 

Now that's a great video.

 

I don't think anyone is saying you should drive your 911 on summer tires in ice or snow. Just that on dry roads in temps around freezing, it is OK as long as you do not push the car too hard.

I live in North Carolina and it can get pretty darn cold here, but usually just for a few days, then warms back up. This week, it was 9 degrees Tuesday morning with a high of 24. I drove my car that day with absolutely no problems. It is supposed to be 70 tomorrow. So for me, buying winter tires just does not make sense. If there is ice or snow on the roads, or any chance for it, I don't drive the car.

For those of you that live in much colder climates where it gets cold and stays cold for months, and need to drive your car daily, I certainly see the need for winter tires, and I would buy them also.

 

This one is one of my favorites, and leaves no doubt the grip difference between snow tires and performance summer tires on a high performance car.

This one is a good one also:

Just curious if you guys that are scared to drive your 911 with summer tires on roads with no snow or ice in the winter park your cars in the warm months when it rains because of potential of hydroplaning with the ultra-wide tires.

 

Oh noooo! Never thought of that. Frankly, never occurred to me and never hydroplaned using the Pzeros.

 

Great video! Anyone in the NE leave their winters on past March?

 

The glass transition temperature of summer tires, and their overall chemistry, makes them a very bad choice for cold weather. Normal breaking increases by about 1/3 in cold and dry conditions.

But that is not why my baby is in the garage with a trickle charger awaiting the occasional 40 degree blip. I drive the GSP and local roads and the grit, salt residue, and pot holes are enough to keep me off the roads.

And while this is not my area of the law, if you hit someone and they have a smart attorney and see that you are on summer tires, I would definitely make a point of it in arguing negligence and liability in a civil suit. The bigger question might also be from your insurance carrier who might take the position that you took an unnecessary risk and therefore you are not covered - particularly if there is real injury or death and they want to get out from backstopping you.

Invest in winter tires or, as I did, a $100.00 trickle charger!
