Thanks for the response. A lot of folks over on the gm-trucks forum are knocking on them, but then a lot of them are hardcore enthusiast and are able to drop 1200.00+ on the tires they want rather than wearing out SR-A's.
I only scared myself once last winter and that's because I was driving way too fast for the conditions. Came over a rise only to find a large drift across the road and cars coming the other way... I don't think any tire would have solved that problem though.
