I just want to say: "Greed is the death of a sucker". I remember once we were transporting watermelons from Temryuk to Sochi. Instead of 10 tons, they loaded 13 tons on us. We changed the tire twice on the Serpentine, then drove to Lermontovo with a flat tire, where we bought two more tubes. We changed one, and kept the other as a spare. Driving through a long tunnel in the mountain, another tube burst. In short, we arrived at the destination with a flat tire. It's good that there were six of them.
