respectively to the load indices 145 and 143 shown in Annex 4 to this Regulation;
               Capable of being fitted without inner tube: "TUBELESS";
              Manufactured during the twenty-fifth week of the year 2003, and
              Requiring to be inflated to 620 kPa for load/speed endurance tests, for which the PSI symbol is 90.
2. In the particular case of tyres having a tyre to rim fitment configuration "A", the marking shall be in the form of the following example:
              235-700 R 450A
              Where:
              235 is the nominal section width in mm
              700  is the outer diameter expressed in mm
                  R  is an indication of the structure of the tyre - see paragraph 3.1.4. of this Regulation
              450  is the nominal diameter of the rim expressed in mm
              A  is the tyre to rim fitment configuration.
              The marking of the load index, speed category symbol, date of manufacture and other markings, shall be as given in the example above.

              3. The positioning and order of the markings constituting the tyre designation shall be the following:
                 a)         The tyre-size designation as defined in paragraph 2.20. of this Regulation shall be grouped as shown in the example above: 255/70 R 22.5 or 235-700 R 450A;
                 b)         The service description comprising the load index/indices and the speed symbol shall be placed immediately after the tyre-size designation as defined in paragraph 2.20. of this Regulation;
                 c)         The symbols "TUBELESS" and "M+S" or "FRT" or "MPT" (and equivalents) may be at a distance from the tyre-size designation
                 d)         If paragraph 6.2.5. of this Regulation is applied, the additional load-capacity indices and speed-category symbol must be shown inside a circle near the nominal load-capacity indices and speed-category-symbol appearing on the tyre sidewall.
