(2) The total weight transmitted to the road surface by any 2 wheels of a vehicle in line transversely shall not exceed 10 tonnes if each such wheel is fitted with 2 pneumatic tyres having the centre of their areas of contact with the road surface not less than 300 millimetres apart measured at right angles to the longitudinal axis of the vehicle or with a wide tyre.
