Why do these trucks have too many axles and tires ▶ 5 ton weight tire change

Relatively short (9.6 m / 32 ft) trucks with five axles are quite common. Its total weight is allowed to be 40 (metric) tons. What makes them a bit special is that three of the five axles (the front two and the last) are steered, which ensures the turning radius is under 20 m / 64 ft.
