I don't know if it was dumb or luck, or maybe dumb luck. I picked up a pallet of concrete from home depot, and immediately had a blowout. My father came to get me and get my jack and spare tire. Changed the tire out and on the way home one of the pallets collapsed. Since I have siderails on my trailer, i have to put 3 pallets up so the forklift guy could get it in level since he can't place it in the trailer. I'm lucky it was strapped otherwise I think it would have gone. Rest of the way home at 25mph with my hazards on shitting my pants praying it would hold.
