Firestone never had a problem with my wife's 2000 Buick which also has tire pressure sensors.

My job requires me to go drive allot regardless of weather (about 600 miles a week and I rarely leave my county). For this reason I need a top of the line snow tire. I am willing to let FE suffer in the winter months as long as I can safely get around when it snows. It has been my experience that Blizzaks are the best. Since Firestone wants to loose me as a customer after years of buying tires from them, I need a new snow tire. Is there anything out there better than Blizzacks?
