Hey, I'm riding on the Pirelli Winter Snowsport 210s aswell....
I live in Vancouver and drive to Whistler almost every weekend, and I've found these snow tires to be great. Compared to the stockers they are night and day. I got my car in Sept of 2001, and I had to change to winter tires in the first winter cause the stockers are so bad.
Anyways, from what people have been telling me the Pirelli Winter Snowsport 210s are some of the best for our car, so don't bother buying new ones. Just make sure you accelerate slowly on the icy surfaces and you won't slip at all.
