The tyre shall be mounted on the measuring rim specified by the manufacturer and is inflated to a pressure specified by the manufacturer. 1. 1. To seat the beads do not exceed the inflation pressure marked on the tyre sidewalls. 1. 2. Having properly seated tyre beads on the rim, adjust the pressure to the value specified for tyre measurements. 2. 3. 4. The tyre fitted on its rim is conditioned to the ambient temperature of the laboratory for at least 24 hours. The pressure is readjusted to the value specified in paragraph 1. The overall width is measured by calliper at six equally-paced points, account being taken of the thickness of the protective ribs or bands. The highest measurement so obtained is taken as the overall width. 5. The outer diameter is determined by measuring the maximum circumference and dividing the figure so obtained by B (3,1416).

Preparing the tyre Mount a new tyre on the test equipment. Wheels used for the test shall be suitable to withstand, with no deformation, the highest value of pressure achievable during the test. Carefully centre the tyre beads on the retention device and adjust the outer distance of the tyre beads to a value corresponding to the width of the rim specified by the manufacturer pursuant to paragraph 4. 1. 10 of this Regulation. Fill the tyre with water taking care that all the air inside the tyre is expelled. Test procedure Activate the apparatus and increase the pressure of the water inside the tyre in order to reach progressively the limit given by two and half times the pressure specified by the tyre manufacturer pursuant to paragraph 4. 1. 12 of this Regulation; 2. 1. 1. in no case, however, the limit value shall be lower than 6 bar or higher than 10 bar. 2. 2. 2. 3. 2. 4. Maintain constant the value of the pressure for at least 10 minutes. Decrease, progressively, the pressure of the water to zero and drain the tyre. Whilst the pressure of the water inside the tyre is higher than the ambient pressure, nobody shall stand inside the test room, that shall be safely locked. 3. Equivalent test methods If a method other than that described above is used, its equivalence must be demonstrated. Annex 9 LOAD/SPEED TEST PROCEDURE 1. 1. 1. 1. 2. 2. 2. 1. Scope and range of application This test procedure is applicable for new tyres corresponding to the characteristics specified in paragraph 3. 4 below. It serves the purpose to assess the suitability of the tyre for the claimed performances. Preparing the tyre Mount new tyres on the test rim specified by the manufacturer pursuant to paragraph 4. 1. 10 of this Regulation. 2. 1. 1. To seat the beads do not exceed the maximum pressure marked on the tyre sidewalls. 2. 2. 2. 3. 2. 4. 2. 5.
