I got the Pirelli Scorpion Snow & Ice mounted on the car almost 2 weeks and have logged about 1000miles since then. I drove 205miles to Vermont through the snowstorm and had no problems.. Highways were covered with an inch or two and I had no problems going 60mph..
Braking- With these things braking from any speed is impressive.. I didn't go out and take measurements but I can stomp on the brakes and not have to worry about stopping..
Dry weather handling was one of the most important things to me and these pass the test with an A+.. I can barely tell I am driving on snowtires.. I have had snow tires on previous cars and I use to dread having to get them mounted but with these, I will cringe no more..
Slow speed steep hill climbing - No problems, I got up a friends driveway that was covered with about 5 inches of snow without a glitch..
I haven't driven in more than 8 inches of snow but for where I live and drive, these are perfect. It is rare to see more than 6inches of snow on our roads so getting something that handles amazingly in 20inches of snow at highway speeds wasn't a priority.. I'll give up speed in those conditions to have a more enjoyable daily commute which typically doesn't involve snow..
Thanks for all the help and advice...
