for either rigid six-wheel vehicles or tractive units for use with semi-trailers?
ATwin-steer rigid six-wheelers are offered
by some manufacturers because they give the lightest unladen weight possible while allowing the same gross weights as 6 X 4 or 6 x 2 chassis.
Another advantage is reduced tyre cost but a disadvantage is that weight distribution can be critical. The main reason why twin-steer tractive units are now popular is because they provide the lowest unladen weight for an articulated outfit with a permissible maximum gross weight of 32 tons while retaining semitrailer interchangeability within a fleet.
