Due to the reduced Tare Mass gained by fitting the Haire Complete Tri Axle Suspension the payload can be increased by 1.1 - 1.9 tonnes as compared to a twin steer. With the Haire designed tri-group, turning circle will be virtually the same as that achieved by a tandem drive prime mover with the same wheelbase. Existing vehicles with a wheelbase of around 4.8 metres have turning circles as low as 15.4m.
Note: Actual turning circle depends on wheel base, steering lock, axle spread, and tandem spread.
