Since it is crappy out and many still don't have snow tires on a question.
if you take your car out and manage to drive a bit how much could you expect your tires to heat up when there is snow/water on the ground and outside temps are in the 30s? And would it be enough to soften up the rubber abit to provide normal roadholding capabilities or close to them?
IE I drove 30 minutes on the highway today, that should have warmed up my tires or at least the air in my tires a bit right? That's why you are supposed to take your tire pressure when the tire is cold.

Rob, frozen rubber will not even come close to warming sufficiently
driving 30 minutes on a frozen highway through snow/ice.
I almost totalled my TT about 3 weeks after I got it. Hadn't gotten snows yet and drove through some snow. Then when I went to stop on less than an inch of snow the car slid/skidded for over 150 feet! ABS was going nuts and the car just kept on sliding. I was not even doing 20mph when I got on the brakes. Could not turn or do anything but enjoy the ride. Came within 5 feet of going into either a pole or oncoming traffic.
Went out that morning and paid $800 for steel wheels and Nokian NRWs. Then the fun began!

It depends on many things
<center><img src="http://members.verizon.net/~vze4phja/images/icetyre.jpg"></center><p>Obviously the temperature, but also your style of driving. All of this is controlled by the tread pattern, and compound of your tyres of course. inflation pressure makes a difference, but you shouldn't be adjusting that to manipulate grip as a rule.
To put it simply, no, a summer tyres isn't going to perform as well in winter as in summer. Remember in summer, they will heat even more. You can go with an all season, but they're obviously a compromise.
The ideal situation is to have the right pattern and compound for the conditions. We were just up at The Rally of the Tall Pines, this past weekend, and for the first morning sections suffered that exact problem. We had Michelin gravel tyres on the rear, and Yokahama snows on the front. The rear slid all over, because the conditions were frozen hard packed sand. The compound was too hard, and the pattern wasn't open enough. At the first service we put Yokahama's on the rear, and all was well.
BTW, whaddaya mean, "no snows on"?

Don't count on it. Trust me!
I TRIED to drive my old ttq on the Potenza's and hit the brakes with just a bit of slush on the road and slid right through an intersection. Luckily nobody was in my way.
Now, on the 'dry' pavement, when it is cold, it is OK, as long as you don't push it.
I'm not going to be brave this morning with my Pilot sport's. I'll wait until it stops snowing, roads clear, and then go to the installer to get my snows on.
