centre lines of the axles are less than 1.35 m apart, must not exceed 20 t:
 (a) decreased by 1 t for each 100 mm by which the axle group's ground contact width is less than 2.4 m; or
 (b) increased by 1 t for each 100 mm by which the axle group's ground contact width exceeds 2.5 m, but not increased to more than 27 t.
 (3) The mass on a tandem axle group fitted with dual tyres, where the centre lines of the axles are at least 1.35 m apart, must not exceed 23 t:
 (a) decreased by 1 t for each 100 mm by which the axle group's ground contact width is less than 2.4 m; or
 (b) increased by 1 t for each 100 mm by which the axle group's ground contact width exceeds 2.5 m, but not increased to more than 27 t.
 (4) The mass on a tri‑axle group fitted with dual tyres, where the centre lines of the axles are less than 1.35 m apart, must not exceed 25 t, decreased by 1 t for each 100 mm by which the axle group's ground contact width is less than 2.4 m.
Note: Under subclause 1.2(3) the centre lines of the axles must be at least 1.2 m apart.

3.3  Total mass limits for special purpose vehicles
  The total mass of a special purpose vehicle must not exceed the least of:
 (a) the sum of the mass allowed for each single axle and axle group on the vehicle; and
 (b) 40 t; and
 (c) the mass worked out using the following formula:
where:
L is the distance in metres between the centre lines of the vehicle's foremost and rearmost axles; and
±G is a number of tonnes:
 (a) to be added at the rate of 1 t for each 100 mm by which the ground contact width of the rearmost axle exceeds 2.5 m; or
 (b) to be subtracted at the rate of 1 t for each 100 mm by which the ground contact width of the rearmost axle is less than 2.4 m.
