My 03 4.4i has pure summer tires on it and I live in Tahoe. Those tires have definitely tested my driving abilities but tomorrow I'm swapping on a set of 18' wheels with blizzaks as I'm tired of the gamble. Amazingly enough with the pure summer tires I've never managed to get it stuck in the feet of snow that we've received however I have been driving in this weather for a long time.
