(cid:145)Ply(cid:146) means a layer of (cid:145)rubber(cid:146) coated parallel cords.

(cid:145)Belt(cid:146) applies to a radial ply or bias belted tyre and means a layer or layers of material or materials underneath the tread,
substantially in the direction of the centre line of the tread to restrict the carcass in a circumferential direction.

laid

(cid:145)Breaker(cid:146) applies to a diagonal ply tyre and means an intermediate ply between the carcass and tread.

(cid:145)Protective breaker(cid:146) applies to a radial ply tyre and means an optional intermediate ply between the tread and the belt to minimise
damage to the belt.

(cid:145)Chafer(cid:146) means material in the bead area to protect the carcass against chafing or abrasion by the wheel rim.

(cid:145)Carcass(cid:146) means that structural part of a pneumatic-tyre other than the tread and outermost, (cid:145)rubber(cid:146) of the sidewalls which, when
inflated, supports the load.

(cid:145)Tread(cid:146) means that part of a pneumatic-tyre which is designed to come into contact with the ground, protects the carcass against

APPROVAL

To retread tyres requires the approval of
the retreading production unit by the approval authorities in accordance with the
requirements of this Regulation. The approval authority shall take the necessary measures as described in this Regulation in order
to ensure that the tyres retreaded in the respective production unit will meet with the requirements stated in this Regulation. The
retread production unit shall be fully responsible for ensuring that the retreaded tyres will meet the requirements of this Regulation and
that they will perform adequately in normal use.

In addition to the normal requirements for the initial assessment of the tyre retreading production unit, the approval authority shall be
satisfied that the procedures, operation, instructions and specification documentation provided by material suppliers are in a language
readily understood by the tyre retreading production unit operatives.

The approval authority shall ensure that the procedures and operations documentation for each production unit contains specifications,
appropriate to the repair materials and processes used, of the limits of repairable damage or penetrations to the tyre carcass, whether
such damage is existing or is caused during the processes of preparation for retreading.

Before granting approval the authority must be satisfied that retreaded tyres conform to this Regulation and that the tests prescribed in
paragraphs 6.5 and 6.6 have been successfully carried out on at least 5 and not necessarily more than 20 samples of retreaded tyres
representative of the range of tyres produced by the retreading production unit.

In the case of each failure being recorded during tests, two further samples of the same specification tyre shall be tested. If either or
both of these second two samples fail, then a final submission of two samples shall be tested.

Preparation:

After buffing, and before the application of new material, each tyre shall be thoroughly re-examined, at least externally, to ensure its
continued suitability for retreading.

The entire surface to which new material is to be applied shall have been prepared without overheating. The buffed surface texture shall
not contain deep buffing lacerations or loose material.

Where procured material is to be used the contours of the prepared area shall meet the requirements of the material manufacturer.

Damage caused during buffing must not exceed defined limits of repair, see paragraph 5.3, and must be repaired.

Buffing damage to diagonal ply tyres shall not extend beyond the outermost carcass ply in the crown area. It shall be assumed that the
first ply encountered is a carcass ply unless a breaker can be positively identified. If a breaker is fitted, localised damage is permissible.

Localised buffing damage to the belt of radial tyres is permissible. For larger damage it is permissible for the complete belt or sections
of the belt to be replaced. Where a protective breaker is fitted, and can be positively identified as such, if it is damaged it is permissible
to remove it and it need not be renewed.

Exposed steel parts shall be treated as soon as possible with appropriate material as defined by the manufacturer of that appropriate
material.

Retreading:

The retreader must ensure that either the manufacturer or the supplier of repair materials, including patches, is responsible for the
following:

(a) defining method(s) of application and storage, if requested by the retreader, in the national language of the country in which the

materials are to be used;

(b) defining limits of damage for which the materials are designed, if requested by the retreader, in the national language of the country

in which the materials are to be used;

(c) ensuring that reinforced patches for tyres, if correctly applied in carcass repairs, are suitable for the purpose;

(d) ensuring that the patches are capable of withstanding twice the maximum inflation pressure as given by the tyre manufacturer;

(e) ensuring the suitability of any other repair materials for the service intended.

The retreader shall be responsible for the correct application of the repair material and for ensuring that the repair is free from any
defects which may affect the satisfactory service life of the tyre.

The area surrounding a reinforced repair to a sidewall or shoulder of a radial ply tyre may bulge slightly when the tyre is fitted and
inflated to the recommended operating pressure. Reinforced repair materials with physical properties that restrict the height of the
bulge to not more than 4 mm shall be used.

The retreader shall ensure that either the manufacturer or the supplier of tread and sidewall material issues specifications concerning
the conditions of storage and use of the material in order to guarantee the material’s qualities. If requested by the retreader, this
information shall be in the national language of the country in which the materials are to be used.

The retreader must ensure that the repair material and/or compound is documented in a manufacturer’s or supplier’s certificate. The
material compound must be suitable for the intended use of the tyre.

The processed tyre shall be cured as soon as possible after the completion of all repairs and building-up operations and at the latest
according to the material manufacturer’s specifications.

The tyre shall be cured for the length of time and at the temperature and pressure, appropriate to, and specified for, the materials and
processing equipment used. The dimensions of the mould must be appropriate to the thickness of the new material and the size of the
buffed tyre.

The thickness of original material after buffing and the average thickness of any new material under the tread pattern after retreading
shall be as given in paragraphs 6.4.8.1 and 6.4.8.2.

6.4.8.1.

The combined thickness of original and new material beneath the base of the grooves of the tread pattern shall be ‡ 3.00 mm and
£ 13.00 mm.

6.4.9.

The service description of a retreaded tyre shall not show either a higher speed symbol or a higher load index than that of the original,
first life, tyre unless approval has been granted to the manufacturer of the original, first life, tyre for that same carcass to be used at the
revised service description.

Information that an original, first life, carcass has been upgraded in this way shall be made freely available by an approval authority to
any retreading production unit and shall be communicated to other parties to the 1958 Agreement (see Article 5 of the Agreement
Concerning the Adoption of Uniform Technical Prescriptions for Wheeled Vehicles, Equipment and Parts which can be Fitted and/or
Used on Wheeled Vehicles and the Conditions for Reciprocal Recognition of Approvals Granted on the basis of these Prescriptions (cid:151)

The standard form shown in annex 1 to Regulation No. 54 shall be used to communicate this information.

6.4.10.

Upgrading of the service description as given in paragraph 6.4.9 shall only be permitted for the first retread of an original, first life
tyre.

Tyres which have been previously retreaded shall not have either the speed symbol or the load index raised above that shown on the
used casing.

Inspection:

After curing, whilst a degree of heat is retained in a tyre, each retreaded tyre shall be examined to ensure that it is free from any
apparent defects. During or after retreading the tyre must be inflated to at least 1.5 bar for examination. Where there is any apparent
defect in the profile of the tyre (e.g. blister, depression, etc.) the tyre shall be specifically examined to determine the cause of this defect.

Before, during or after retreading the tyre shall be checked at least once for the integrity of its structure by means of a suitable
inspection method.

For the purposes of quality control a number of retreaded tyres shall be subjected to destructive or non destructive testing or
examination. The quantity of tyres checked and the results shall be recorded.

dual, corresponding respectively to the load indices 150 and 146 shown in annex 4 to this Regulation;

Intended to be used without an inner tube ((cid:145)TUBELESS(cid:146)) and of Snow type (M+S);

Retreaded in the weeks 25, 26, 27 or 28 of the year 2003.

Requiring to be inflated to 620 kPa for load/speed endurance tests, for which the PSI symbol is 90.

The positioning and order of the markings constituting the tyre designation shall be as follows:

(a) The size designation, comprising the nominal section width, the nominal aspect ratio, the type-of-structure symbol (where applicable) and the

nominal rim diameter, shall be grouped as shown in the above example, that is: 295/80R22,5;

(b) The service description, comprising the load indices and the speed symbol shall be placed together near the size designation. It may either precede

the size designation or follow it or be placed above or below it;

(c) The symbol (cid:145)TUBELESS(cid:146) and (cid:145)M+S(cid:146) may be at a distance from the size designation symbol.

(d) The word (cid:145)RETREAD(cid:146) may be at a distance from the size-designation symbol.

(e)

If paragraph 3.2.5 of this Regulation is applied, the additional service description (Unique Point), comprising the load indices and speed symbol,
must be shown inside a circle near the nominal service description appearing on the tyre sidewall.

ANNEX 5

TYRE SIZE DESIGNATION AND DIMENSIONS

(in accordance with ECE Regulation No 54)

For this information refer to annex 5 of ECE Regulation No 54

Note that with reference to paragraph 6.5.4 of this Regulation, the outer diameter of a retreaded tyre may in all cases be
greater than that shown in the tables in annex 5 to Regulation No 54 but by no more than 1.5 per cent.

ANNEX 6

METHOD OF MEASURING PNEUMATIC TYRES

1. The tyre shall be mounted on the test rim specified by the retreader and inflated to the Nominal Inflation Pressure
quoted in the nominated International Tyre Standard (see paragraph 4.1.4.7 of this Regulation) in relation to the
Maximum load carrying capacity fot that Size and Load index.

2. The tyre, fitted to the appropriate rim, shall be conditioned to the ambient temperature of the laboratory for at least

24 hr save as otherwise required by paragraph 6.6.3 of this Regulation.

3. The pressure shall be re-adjusted to the value in paragraph 1 of this annex.

4. The overall width shall be measured at six equally spaced points around the tyre, taking account of the thickness of

any protective ribs or bands. The highest reading obtained shall be taken as the overall width.

5. The outer diameter shall be calculated from a measurement of the maximum circumference of the inflated tyre.

ANNEX 7

PROCEDURE FOR LOAD/SPEED ENDURANCE TESTS

(in principle in accordance with Regulation No 54)

1.

Preparing the tyre

1.1. Mount a retreaded tyre on the test rim specified by the retreader.

1.2. Use a new inner tube or combination of inner tube, valve and flap (as required) when testing tyres with inner

tubes.

1.3.

Inflate the tyre to the pressure corresponding to the pressure index as specified in paragraph 3.2.10 of this
Regulation.

1.4.

Condition the tyre and wheel assembly at test-room temperature for not less than 3 hr.

1.5.

Readjust the tyre pressure to that specified in paragraph 1.3 of this annex.

2.

Test Procedure

2.1. Mount the tyre and wheel assembly on the test axle and press it against the outer face of a smooth surfaced
power-driven test drum 1.70 m – 1 per cent diameter having a surface at least as wide as the tyre tread. In certain
cases a 2.00 m – 1 per cent diameter drum maybe used.

2.2. Apply to the test axle a series of test loads equal to a percentage of the load indicated in annex 4 to this
Regulation, corresponding to the load index indicated on the tyre, and in accordance with the test programme
below. Where the tyre has load capacity indices for operation in both single and twin or dual formation the load
corresponding to the load index for single operation shall be used for the test.

2.2.1.

In the case of a tyre with a load index £ 121 and a speed symbol ‡ Q (160 km/h), the test procedure shall be as
specified in paragraph 3 of this annex.

2.2.2. For all other tyres the test procedure is as shown in appendix 1 to this annex.

2.3.

Endurance Test Programme (cid:151) See also appendix 1 to this annex.

2.3.1. The tyre pressure shall not be corrected throughout the test and the test load shall be kept constant throughout

each of the three test stages.

2.3.2. During the test the temperature of the test room shall be maintained at between 20 (cid:176)C and 30 (cid:176)C unless the tyre

manufacturer or retreader agrees to the use of a higher temperature.

2.4.

The endurance test programme shall be carried out without interruption.

3.

Load/Speed test procedure for tyres with a load index £ 121 and a speed symbol ‡ Q (160 km/h):

3.1.

The load on the wheel and tyre shall be the following percentage of that corresponding to the load index of the
tyre:

3.1.1. 90 per cent when tested on a drum of 1.70 m – 1 per cent diameter;

3.1.2. 92 per cent when tested on a drum of 2.00 m – 1 per cent diameter.

3.2.

The initial phase test speed shall be 20 km/h less than that indicated by the speed symbol for the tyre.

3.2.1. Time taken to reach initial test speed shall be 10 min.

3.2.2. The duration of the first phase shall be 10 min.

3.3.

The second phase test speed shall be 10 km/h less than that indicated by the speed symbol for the tyre.

3.3.1. The duration of the second phase shall be 10 min.

3.4.

The final phase test speed shall be the speed corresponding to that indicated by the speed symbol for the tyre.

3.4.1. The duration of the final phase shall be 30 min.

3.5.

The duration of the entire test shall be 1 hr.

4.

Equivalent test method:

If a test method other than that given in paragraphs 2 or 3 of this annex is used, its equivalence must be
demonstrated.
