4. TIRES.

(1) No motor-lorry tire shall be of a less width than 3 in.

(2) The minimum width of any tire used on any motor-lorry shall be such that the intensity of pressure of such tire on the surface of the highway resulting from the weight of the motor-lorry, together with the maximum load it is entitled to carry, shall not exceed the following :—

400 lb. per inch of width of tire for tires up to and including 5 in. in width.

600 lb. per inch of width of tire for tires more than 5 in. but not more than 6 in. in width.

(3) Twin or dual tires shall for the purpose of width be deemed to be a single tire having a width equal to the sum of the widths of both tires.

(4) The thickness of any non-pneumatic rubber tire on any wheel of any motor-lorry shall be not less than the following :—

⅞ in. for any tire not more than 5 in. in width :

1 in. for any tire more than 5 in. but not more than 8 in. in width :

1¼ in. for any tire more than 8 in. in width.

(5) No person shall operate any motor-lorry having tires of a less thickness than those hereinbefore prescribed.

(6) The tire of each wheel of a motor-lorry, if such tire is not of a soft or elastic material, shall be smooth, and shall, where the tire touches the surface of the road or other base whereon the motor-lorry moves or rests be flat : Provided that the edges of the tire may be bevelled or rounded to the extent in the case of each edge of not more than half an inch, measured as the shortest straight line across the width of the surface of the bevelled or rounded portion : Provided also that if the tire is constructed of or faced with separate plates the plates may be separated by parallel spaces which shall be disposed throughout the outer surface of the tire so that nowhere shall the aggregate extent of the space or spaces in the course of a straight line drawn horizontally across the circumference of the wheel exceed one-eighth part of the width of the tire.

(7) No person shall operate any motor-lorry having any tire which, if not of a soft or elastic material, is not smooth and flat (to the extent aforesaid and subject to the foregoing proviso), or which, if constructed of or faced with separate plates, has spaces greater than the spaces hereinbefore prescribed.

(5) In any case in which the maximum speed fixed by a controlling authority in respect of any road is less than the speed fixed by the foregoing clauses the maximum speed shall be that fixed by such controlling authority.

(6) Notwithstanding anything hereinbefore contained, a controlling authority may give written permission in respect of any particular motor-lorry or in respect of any particular class of motor-lorry to travel at a maximum speed in excess of the maximum speed hereinbefore provided, and the speed so permitted shall for the purposes of these regulations be deemed to be the maximum speed hereunder : Provided always that—

(a) Such permission shall be given only in respect of motor-lorries licensed for the carriage of passengers or licensed for the carriage of goods and passengers, and fitted with pneumatic tires on all wheels.

(2) Without the written permission of the controlling authority, no person shall operate any motor-lorry the greatest width of the load of which is more than 8 ft., or which carries a load (otherwise than on a trailer) so that the load overhangs the axis of the rear wheels by more than 8 ft., or extends further forward than the radiator, or in any way obscures the vision of the driver to his front or on either side.

(3) Such permission may be expressed to be subject to such conditions as to—

(a) Width, length, or height of load :

(b) Duration of permission :
