I was driving home tuesday night in the slow lane. I had pulled over to give my wife insurance info because she was on the way to the hospital. As I was getting back up to speed 45-70 there were cars merging from a on ramp when I noticed a bag of cement near the white lines. I started to slow but too late, the truck missed it, the driverside front tire on the trailer nailed it. the trailer wiggled a little then through the lights of cars behind me I saw all the smoke. the tire was destroyed. It looks like a bomb went off in the tire. I will post pics tomorrow since my wife is back from the hospital.
