REDUCIBLE LOADS: LEGAL/NORMAL AXLE WEIGHTS (M.R. 575/88)
Weights listed are maximums. Weight on steer axles are calculated at 10 kg/mm width of tire. All other axles are calculated at 9 kg/mm width tire.
Example: Truck tractor with 280mm tires for Normal and Winter Seasonal: 280 x 2 x 10 = 5600 kg. This would be the legal maximum for this tire size.
