Width' specified in the 'Nominated Standard' for its size designation and type.
23.2.2.2.3.2.       its 'Size Factor' shall be at least as large as the minimum 'Size Factor' specified in the `Nominated Standard' for its size designation and type. If the 'Nominated Standard does not specify a minimum 'Size Factor', this shall be calculated as:

         Minimum 'Size Factor' = 0.97 (SW + 2SH) + DR

         where:

         SW = specified 'Section Width' [##]

         SH = 1/2 of (specified outer diameter nominal rim diameter)

         DR = nominal 'Rim' diameter

23.2.2.2.4.              Resistance to 'Bead' unseating requirements (for tubeless tyres only)

         When tested in accordance with Clause 23.3.2 the applied force required to unseat the tyre 'Bead' at the point of contact shall not be less than:

23.2.2.2.4.1.       6,670 N for tyres with a 'Specified Design Section Width' of less than 6.3 inches, or 160 mm;
23.2.2.2.4.2.       8,890 N for tyres with a 'Specified Design Section Width' of 6.3 inches or 160 mm or more but less than 8 inches or 205 mm; or
23.2.2.2.4.3.       11,120 N for tyres with a 'Specified Design Section Width' of 8 inches or 205 mm or more.
23.2.2.2.5.              Tyre strength requirements

         Each tyre shall meet the requirements for minimum breaking energy specified in Table 3 when tested in accordance with Clause 23.3.3.

23.2.2.2.6.              Tyre endurance requirements

         After completion of the laboratory test wheel endurance test specified in Clause 23.3.4 no tyre shall have 'Tread Separation', 'Ply Separation', 'Cord Separation', 'Belt Separation' or 'Bead Separation', 'Chunking', or 'Broken Cords'.

23.2.2.2.7.              High speed test requirements

         After completion of the high speed test specified in Clause 23.3.5 no tyre shall have 'Tread Separation', 'Ply Separation', 'Cord Separation', 'Belt Separation' or 'Bead Separation', 'Chunking' or 'Broken Cords'.

23.2.3.                          Labelling Requirements.

         Each tyre shall be conspicuously labelled on both 'Sidewalls' in the case of symmetrical tyres and at least on the outer 'Sidewalls' in the case of 'Asymmetrical Tyres' with each of the following permanently moulded in letters and figures at least 3.8 mm high and depth at least 0.25 mm if below the background surface or 0.4 mm if above the background

23.2.3.1.                    tyre size designation, which includes the 'Speed Category' symbol as determined from Table 4 either within the size designation or adjacent to the size designation as part of the 'Service Description', and 'Tyre Carcass Construction Symbol' for 'Radial Ply Tyres' or 'Bias-belted Tyres' and optionally, in the case of 'Diagonal Ply';;
23.2.3.2.                    the 'Maximum Load Rating' for the tyre expressed in kilograms followed by the word "kilograms" or the abbreviation 'kg' or the 'Maximum Load Rating' for the tyre expressed in pounds followed by the word "pounds" or the abbreviation "lbs" or the 'Load Index' symbol (from Table 2) adjacent
