I can get 4 Bridgestone Turanza Serenitys 205 60 16 for $302 shipped after coupon. This is a V-rated 75000 mile 600AA UTOG rating. The local Firestone dealer quoted me $137 per tire plus valve stems, mounting, balancing for stupid silly $611 out the door. He said that my price per tire was $40 under his cost. I asked if they were directional and he said no, you can cross rotate them. Walmart charges $10 per tire IIRC for mounting, lifetime rotation and balancing. Valve stems are cheap there or get your own.
$81.97 / tire
