The approval mark shall be clearly legible and be indelible.\n\n5.6. Annex 2 to this Regulation gives an example of the arrangement of the approval mark.\n\n5.7. Subsequent re-treading in accordance with Regulation No. 109\n\nIn the case where, during the course of production of a particular tyre type, the manufacturer has obtained a new approval for that same tyre type to be marked with a service description indicating a higher load index or different speed symbol than the earlier marking and where the tyre manufacturer authorizes the earlier tyre type to be re-treaded and marked with the later service description, the tyre manufacturer shall complete the Communication document given in Annex 9 to this Regulation and shall submit this to the Type Approval Authority that has granted the new approval. If the authorization for upgrading only applies to tyres from a particular manufacturing plant, or produced during particular production periods, the information necessary to identify the tyres shall be stated on the Communication document.\n\nThe Type Approval Authority shall communicate this information to other Parties to the Agreement, which apply this Regulation, and tyre manufacturers or Type Approval Authorities shall release this information on the request of any re-treading production unit that is approved in accordance with Regulation No. 109.\n\n6. Specifications\n\n6.1. Dimensions of tyres\n\n6.1.1. Section width of a tyre\n\n6.1.1.1. The section width shall be obtained by means of the following formula:\n\nS = S1 + K (A - A1),\n\nWhere:\n\nS is the \"section width\" rounded to the nearest millimetre and measured on the measuring rim;\n\nS1 is \"the nominal section width\" in millimetres, as shown on the sidewall of the tyre in the tyre designation as prescribed;\n\nA is the width of the measuring rim in millimetres, as shown by the manufacturer in the descriptive note; and\n\nA1 is the width of the theoretical rim in millimetres.\n\nA1 shall be taken to equal S1 multiplied by the factor x as specified by the manufacturer, and K shall be taken to equal 0.4.\n\n6.1.1.2. However, for the existing types of tyres whose designation is given in the first column of the tables in Annex 5 to this Regulation, the section width shall be deemed to be that given opposite the tyre designation in those tables.\n\n6.1.1.3. However, for tyres identified by the \"tyre to rim fitment configuration\" (see paragraph 3.1.12.) symbol \"A\", K shall be taken to equal 0.6.\n\n6.1.2. Outer diameter of a tyre\n\n6.1.2.1. The outer diameter of a tyre shall be obtained by means of the following formula:\n\nD = d + 2H\n\nwhere:\n\nD is the outer diameter expressed in millimetres;\n\nd is the conventional number defined in paragraph 2.20.1.3. above, expressed in millimetres;\n\nH is the nominal section height rounded to the nearest millimetre and is equal to\n\nH = S1 • 0.01 Ra, where\n\nS1 is the nominal section width in millimetres;\n\nRa is the nominal aspect ratio;\n\nall as shown on the sidewall of the tyre in the tyre-size designation in conformity with the requirements of paragraph 3.4. above.\n\n6.1.2.2. However, for the existing types of tyres whose designation is given in the first column of the tables in Annex 5 to this Regulation, the outer diameter shall be deemed to be that given opposite the tyre designation in those tables.\n\n6.1.2.3. However, for tyres identified by the \"tyre to rim fitment configuration\" (see paragraph 3.1.12.) symbol \"A\", the outer diameter shall be that specified in the tyre-size designation as shown on the sidewall of the tyre.\n\n6.1.3. Method of measuring tyres\n\n The dimensions of tyres shall be measured by the procedure described in Annex 6 to this Regulation.\n\n6.1.4. Tyre section width specifications\n\n6.1.4.1. The overall width of a tyre may be less than the section width or widths determined pursuant to paragraph 6.1.1. above.\n\n6.1.4.2. It may exceed that value by 4 per cent in case of radial-ply tyres and by 8 per cent in the case of diagonal (bias-ply) tyres. However, for tyres with nominal section width exceeding 305 mm intended for dual mounting (twinning), the value determined pursuant to paragraph 6.1.1. above shall not be exceeded by more than 2 per cent for radial-ply tyres with nominal aspect ratio higher than 60, or 4 per cent for diagonal (bias-ply) tyres. The respective limits shall be rounded to the nearest millimetre (mm).\n\n6.1.4.3. However, for tyres identified by the \"tyre to rim fitment configuration\" (see paragraph 3.1.12.) symbol \"A\", the overall width of the tyre, in the lower area of the tyre, equals the nominal width of the rim on which the tyre is mounted, as shown by the manufacturer in the descriptive note, increased by 27 mm.\n\n6.1.5. Tyre outer diameter specifications\n\n The outer diameter of a tyre must not be outside the values dmin and dmax obtained from the following formulae:\n\nDmin = d + 2 • Hmin\n\nDmax = d + 2 • Hmax\n\nwhere:\n\nHmin = H • a rounded to the nearest mm\n\nHmax = H • b rounded to the nearest mm\n\n6.1.5.1. For sizes listed in Annex 5 and for tyres identified by the \"tyre to rim fitment configuration\" (see paragraph 3.1.12.) symbol \"A\", the nominal section height H is equal to:\n\n H = 0.5 (D-d), rounded to the nearest mm - for references see paragraph 6.1.2.1.\n\n6.1.5.2. For other sizes, not listed in Annex 5\n\n \"H\" and \"d\" are as defined in paragraph 6.1.2.1.\n\n6.1.5.3. Coefficients \"a\" and \"b\" are respectively:\n\n6.1.5.3.1. Coefficient \"a\" = .97\n\n6.1.5.3.2. Coefficient \"b\" Radial Diagonal\n\n For normal use tyres 1.04 1.07\n\n For special use tyres 1.06 1.09\n\n6.1.5.3.3. For snow tyres the outer diameter shall not exceed the following value\n\nDmax,snow = 1.01 • Dmax rounded to the nearest mm\n\nwhere Dmax is the maximum outer diameter established in conformity with the above.\n\nFor tyres of the category of use, \"snow tyre\" the outer diameter (Dmax) established in conformity with the above may be exceeded by one per cent.\n\n6.2. Load/speed endurance test\n\n6.2.1. Each type of tyre shall undergo at least one load/speed endurance tests carried out by the procedure described in Annex 7 to this Regulation.\n\n6.2.2. A tyre which, after undergoing the endurance test, does not exhibit any tread separation, ply separation, cord separation, chunking or broken cords shall be deemed to have passed the test.\n\n6.2.3. The outer diameter of the tyre, measured six hours after the load/speed endurance test, must not differ by more than 3.5 per cent from the outer diameter as measured before the test.\n\n6.2.4. Where application is made for the approval of a type of tyre for the load/speed combinations given in the table in Annex 8, the endurance test prescribed in paragraph 6.2.1. above need not be carried out for load and speed values other than the nominal values.\n\n6.2.5. Where application is made for the approval of a type of tyre, which has a load/speed combination in addition to the one that is subject to the variation of load with speed given in the table in Annex 8, the endurance test prescribed in paragraph 6.2.1. above shall also be carried out on a second tyre of the same type at the additional load/speed combination.\n\n6.3. Tread pattern of a tyre\n\n6.3.1. In order to be classified as a \"special use tyre\" a tyre shall have a block tread pattern in which the blocks are larger and more widely spaced than for normal tyres and have the following characteristics:\n\nFor C2 tyres: a tread depth ≥ 11 mm and void to fill ratio ≥ 35 per cent\n\nFor C3 tyres: a tread depth ≥ 16 mm and void to fill ratio ≥ 35 per cent\n\n6.3.2. In order to be classified as a 'professional off-road tyre', a tyre shall have all of the following characteristics:\n\n(a) For C2 tyres:\n\n (i) A tread depth ≥ 11 mm;\n\n (ii) A void to fill ratio ≥ 35 per cent;\n\n (iii) A maximum speed rating of ≤ Q.\n\n(b) For C3 tyres:\n\n (i) A tread depth ≥ 16 mm;\n\n (ii) A void to fill ratio ≥ 35 per cent;\n\n (iii) A maximum speed rating of ≤ K.\n\n7. Modification and extension of approval of a tyre type\n\n7.1. Every modification of a tyre type shall be notified to the Type Approval Authority, which approved the tyre type. That Authority may then either:\n\n7.1.1. Consider that the modifications made are unlikely to have an appreciable adverse effect and that in any case the tyre still meets the requirements; or\n\n7.1.2. Require a further test report from the Technical Service responsible for carrying out the tests.\n\n7.2. A modification of the tread pattern of the tyre shall not be considered to necessitate a repetition of the tests prescribed in paragraph 6. of this Regulation.\n\n7.3. Confirmation or refusal of approval, specifying the alterations, shall be communicated by the procedure specified in paragraph 5.3. above to the Parties to the Agreement which apply this Regulation.\n\n7.4. The competent Type Approval Authority issuing the extension of approval shall assign a series number for such an extension and inform thereof the other Parties to the 1958 Agreement applying this Regulation by means of a communication form conforming to the model in Annex 1 to this Regulation.\n\n8. Conformity of production\n\n The conformity of production procedures shall comply with those set out in the 1958 Agreement, Schedule 1 (E/ECE/TRANS/505/Rev.3) with the following requirements:\n\n8.1. Tyres approved under this Regulation shall be so manufactured as to conform to the type approved, by meeting the requirements set forth in paragraph 6. above.\n\n8.2. The Type Approval Authority, which has granted type approval, may at any time verify the conformity control methods applied in each production facility. For each production facility, the normal frequency of these verifications shall be once every two years.\n\n9. Penalties for non-conformity of production\n\n9.1. The approval granted in respect of a type of tyre pursuant to this Regulation may be withdrawn if the requirement laid down in paragraph 8.1. above is not complied with or if the tyres taken from the series have failed to pass the tests prescribed in that paragraph.\n\n9.2. If a Party to the Agreement, which applies this Regulation, withdraws an approval it has previously granted, it shall forthwith so notify the other Contracting Parties applying this Regulation, by means of a communication form conforming to the model in annex 1 to this Regulation.\n\n10. Production definitively discontinued\n\n If the holder of an approval completely ceases to manufacture a type of tyre approved in accordance with this Regulation, he shall so inform the Type Approval Authority, which granted the approval. Upon receiving, the relevant communication that Authority shall inform thereof the other Parties to the 1958 Agreement applying this Regulation by means of copies of the communication form conforming to the model in Annex 1 to this Regulation.\n\n11. Names and addresses of Technical Services responsible for conducting approval tests, and of Type Approval Authorities\n\n11.1. The Contracting Parties to the 1958 Agreement which apply this Regulation shall communicate to the United Nations Secretariat the names and addresses of the technical services responsible for conducting approval tests and, where applicable, of the approved test laboratories and of the Type Approval Authorities which grant approval and to which forms certifying approval or extension of approval or refusal of approval or withdrawal of approval or production definitively discontinued, issued in other countries, are to be sent.\n\n11.2. The Contracting Parties to the 1958 Agreement, which apply this Regulation, may designate laboratories of tyre manufacturers, as approved, test laboratories.\n\n11.3. Where a Contracting Party to the 1958 Agreement applies paragraph 11.2. above, it may, if it so desires, be represented at the tests by one or more persons of its choice.\n\nExplanatory figure\n\n(See paragraph 2. of the Regulation)\n\n \n\n\n\n \n\n \n\nAnnex 1\n\nCommunication\n\n(Maximum format: A4 (210 x 297 mm))\n\n \n\n[[7]](#_ftn10)\n\n \n\nconcerning[[8]](#_ftn11): Approval granted\n\n Approval extended\n\n Approval refused\n\n Approval withdrawn\n\n Production definitively discontinued\n\nof a type of tyre for motor vehicles pursuant to Regulation No. 54\n\n \n\nApproval No.:..................Extension No.: ......................\n\n1.

Annexed to this communication is a list of documents in the approval file deposited at the Type Approval Authorities having delivered the approval and which can be obtained upon request.\n\n \n\nAnnex 2\n\n \n\nArrangement of approval mark\n\n \n\n\n\na = 12 mm (min.)\n\n \n\nThe above approval mark affixed to a tyre shows that the type of tyre concerned has been approved in the Netherlands (E 4) under approval number 002439. The first two digits of the approval number indicate that the approval was granted in accordance with the requirements of Regulation No. 54 in its original form.\n\nNote: The approval number must be placed close to the circle and either above or below the \"E\" or to left or right of that letter. The digits of the approval number must be on the same side of the \"E\" and face in the same direction. The use of Roman numerals as approval numbers should be avoided so as to prevent any confusion with other symbols.\n\n \n\nAnnex 3\n\nArrangement of tyre markings\n\n \n\n\n\n(*) PSI marking instead of kPa is allowed for tyres first type approved before 1 January 2018.\n\n \n\n \n\n- Minimum heights of markings(mm)\n- Tyres of nominal rim diameter 508 mm (Code 20) or of nominal section width 235 mm (Code 9) Tyres of nominal rim diameter 508 mm (Code 20) or of nominal section width 235 mm (Code 9)\n- B 6 9\n- C 4\n- D 6\n\n\n1. These markings define a tyre:\n\nHaving a nominal section width of 255;\n\nHaving a nominal aspect ratio of 70;\n\nOf radial-ply structure (R);\n\nHaving a nominal rim diameter of 572 mm, for which the symbol is 22.5;\n\nHaving load capacities of 3,150 kg when single and 2,900 kg when twinned (dual), corresponding respectively to the load indices 148 and 145 shown in Annex 4 to this Regulation;\n\nHaving a reference speed of 100 km/h corresponding to speed category symbol: J;\n\n Classified in the category of use Snow: M+S;\n\nAble to be used additionally at 120 km/h (speed category symbol L) with a load capacity of 3,000 kg when single and 2,725 kg when twinned (dual), corresponding respectively to the load indices 145 and 143 shown in Annex 4 to this Regulation;\n\n Capable of being fitted without inner tube: \"TUBELESS\";\n\nManufactured during the twenty-fifth week of the year 2003, and\n\nRequiring to be inflated to 620 kPa for load/speed endurance tests, for which the PSI symbol is 90.\n\n2. 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:\n\n235-700 R 450A\n\nWhere:\n\n235 is the nominal section width in mm\n\n700 is the outer diameter expressed in mm\n\nR is an indication of the structure of the tyre - see paragraph 3.1.4. of this Regulation\n\n450 is the nominal diameter of the rim expressed in mm\n\nA is the tyre to rim fitment configuration.\n\nThe marking of the load index, speed category symbol, date of manufacture and other markings, shall be as given in the example above.\n\n3. The positioning and order of the markings constituting the tyre designation shall be the following:\n\na) 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;\n\nb) 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;\n\nc) The symbols \"TUBELESS\" and \"M+S\" or \"FRT\" or \"MPT\" (and equivalents) may be at a distance from the tyre-size designation\n\nd) 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.\n\n \n\nAnnex 4\n\nList of symbols of load-capacity indices\n\n| Load-capacity index | Corresponding maximum mass to be carried (kg) |\n| --- | --- |\n| 60

The tyre is mounted on the measuring rim specified by the manufacturer pursuant to paragraph 4.1.11. of this Regulation and is inflated to a pressure specified by the manufacturer pursuant to paragraph 4.1.12. of this Regulation.\n\n2. The tyre fitted on its rim is conditioned to the ambient temperature of the laboratory for at least 24 hours.\n\n3. The pressure is readjusted to the value specified in paragraph 1. above.\n\n4. The overall width is measured by caliper at six equally-spaced points, account being taken of the thickness of the protective ribs or bands. The highest measurement so obtained is taken as the overall width.\n\n5. The outer diameter is calculated from the maximum circumference.\n\n \n\nAnnex 7\n\nProcedure for load/speed endurance tests\n\n1. Preparing the tyre\n\n1.1. Mount a new tyre on the test rim specified by the manufacturer pursuant to paragraph 4.1.11. of this Regulation.\n\n1.2. Use a new inner tube or combination of inner tube, valve and flap (as required) when testing tyres with inner tubes.\n\n1.3. Inflate the tyre to the pressure corresponding to the pressure index specified by the manufacturer pursuant to paragraph 4.1.12. of this Regulation.\n\n1.4. Condition the tyre-and-wheel assembly at test-room temperature for not less than three hours.\n\n1.5. Readjust the tyre pressure to that specified in paragraph 1.3. above.\n\n2. Test procedure\n\n2.1. Mount the tyre-and-wheel assembly on the test axle and press it against the outer face of a smooth power-driven test drum 1.70 m 1 per cent in diameter having a surface at least as wide as the tyre tread.\n\n2.2. Apply to the test axle a series of test loads expressed in per cent of the load indicated, in Annex 4 to this Regulation, opposite the load index engraved on the sidewall of the tyre, in accordance with the test programme below. Where the tyre has load-capacity indices for both single and twinned utilization, the reference load for single utilization shall be taken as the basis for the test loads.\n\n2.2.1. In the case of tyres with a speed category symbol above P, test procedures are as specified in paragraph 3.\n\n2.2.2. For all other tyre types, the endurance test programme is shown in Appendix 1 to this annex.\n\n2.3. The tyre pressure must not be corrected throughout the test and the test load must be kept constant throughout each of the three test stages.\n\n2.4. During the test the temperature in the test-room must be maintained at between 20 °C and 30 °C or at a higher temperature if the manufacturer so agrees.\n\n2.5. The endurance-test programme shall be carried out without interruption.\n\n3. Load/speed test programme for tyre with speed category symbol Q and above\n\n3.1. This programme applies to:\n\n3.1.1. All tyres marked with load capacity index in single 121 or less.\n\n3.1.2. Tyres marked with load capacity index in single 122 and above and with the additional marking \"C\", or \"LT\", referred to in paragraph 3.1.13. of this Regulation.\n\n3.2. Load placed on the wheel as a percentage of the load corresponding to the load index:\n\n3.2.1. 90 per cent when tested on a test drum 1.70 m 1 per cent in diameter;\n\n3.2.2. 92 per cent when tested on a test drum 2.0 m 1 per cent in diameter.\n\n3.3. Initial test speed: speed corresponding to the speed category symbol less 20 km/h;\n\n3.3.1. Time to reach the initial test speed 10 min.\n\n3.3.2. Duration of the first step = 10 min.\n\n3.4. Second test speed: speed corresponding to the speed category symbol less 10 km/h;\n\n3.4.1. Duration of the second step = 10 min.\n\n3.5. Final test speed: speed corresponding to the speed category symbol:\n\n3.5.1. Duration of the final step = 30 min.\n\n3.6. Total test duration: 1 h.\n\n4. Equivalent test methods\n\n If a method other than that described in paragraph 2. above is used, its equivalence must be demonstrated.\n\n \n\nAnnex 7 - Appendix 1\n\nEndurance-test programme\n\n- Load index Tyre speed category symbol Test-drum speed Load placed on the wheel as a percentage of the load corresponding to the load index\n- Radial-ply km.h-1 Diagonal (bias-ply) km.h-1 7 h. 16 h. 24 h.\n- 122 or more FGJKLM 32 40 48 56 64 72 32324048-- 66 % 84 % 101 %\n- 121 or less FGJK 32 40 48 56 32404856\n- L MNP 64 80 88 96 56 64-- 70 % 4 h.75 %75 %75 % 88 % 6 h. 97 %97 %97 % 106 % 114 %114 %114 %\n- Notes:(1) \"Special-use\" tyres (see paragraph 2.1.3. of this regulation) should be tested at a speed equal to 85 per cent of the speed prescribed for equivalent normal tyres.(2) Tyres with load index 122 or more, speed category symbols N or P and the additional marking \"LT\", or \"C\", referred to in paragraph 3.1.13. of this regulation, shall be tested with the same programme as specified in the above table for tyres with load index 121 or less.\n\n\n \n\n \n\nAnnex 7 - Appendix 2\n\nRelation between the pressure index and the units of pressure\n\n| Pressure
