Question

why do the load carrying heavy vehicles have large number of wheel?

Answer 1

Thanks for your question !

    Very simple! As the load carrying large and heavy vehicle more and wide area. Hence, it will apply more pressure in ratio to its area and weight. To distribute this pressure, there will be obvious need of force. This force is given by the tires. Hence, more the pressure, it will need more force. And thus, more tires (large number of tires) would be used.
