(6.) 6.1. Dimensional requirements 6.1.1. Section width of a tyre 6.1.1.1. Except as provided by section 6.1.1.2, the section width is calculated by the following formula: S = S1 + K (A−A1), where: S = the ‘section width’ expressed in mm ( 13 ) and measured on the measuring rim; S1 = the ‘nominal section width’ in mm as shown on the sidewall of the tyre in the tyre-size designation as prescribed; A = the width (expressed in mm) of the measuring rim, as shown by the manufacturer in the descriptive note, (see section 6.11 of Annex I, Appendix 1); A1 = the width (expressed in mm) of the theoretical rim; it is taken to equal S1 multiplied by the factor x as specified by the tyre manufacturer (see section 6.15 of Annex I, Appendix 1); and K is taken to equal 0.4. 6.1.1.2. However, for the types of tyre for which the size designation is given in the first column of the tables in Appendix 5 A or 5 B, the measuring rim width (A) and the section width (S) are those given opposite the tyre size designation in those tables. 6.1.2. Outer diameter of a tyre 6.1.2.1. Except as provided by secton 6.1.2.2, the outer diameter of a tyre is calculated by the following formula: D = d + 0,02H where: — D is the outer diameter expressed in mm, — d is the conventional number defined in section 2.17.1.3, expressed in mm, — H is the nominal section heigth in mm and is equal to S1 × 0,01 Ra; where: — Ra is the nominal aspect ratio, all as shown on the sidewall of the tyre in the tyre-size designation in conformity with the requirements of section 3. 6.1.2.2. However, for the types of tyres for which the size designation is given in the first column of the tables of Appendix 5 the outer diameter is that given opposite the tyre size designation in those tables. 6.1.3. Method of measuring tyre dimensions The actual dimensions of tyres are measured as prescribed in Appendix 6. 6.1.4. Tyre section width: specification of tolerance 6.1.4.1. The overall width of a tyre may be less than the section width determined pursuant to section 6.1.1 or shown in Appendix 5; 6.1.4.2. It may not exceed that value by more than the following: 6.1.4.2.1. diagonal (bias-ply) tyres: 6 % for passenger car tyres, 8 % for commercial vehicle tyres; 6.1.4.2.2. radial-ply tyres: 4 %; and 6.1.4.2.3. in addition, if the tyre has a special protective band, the figure as increased by the above tolerances may be exceeded by 8 mm. 6.1.4.2.4. However, for tyres of a section width exceeding 305 mm intended for dual (twin) mounting the nominal value must not be exceeded by more than 2 % for radial-ply or 4 % for diagonal (bias-ply) tyres. 6.1.5. Tyre outer diameter: specification of tolerance The outer diameter of a tyre must not be outside the values Dmin and Dmax obtained from the following formulae: Dmin = d + (2H × a) Dmax = d + (2H × b) 6.1.5.1. for sizes listed in Appendix 5: H = 0,5 (D — d) — (for references see section 6.1.2.2). 6.1.5.2. for other sizes not listed in Appendix 5: ‘H’ and ‘d’ are as defined in section 6.1.2.1. 6.1.5.3. coefficients ‘a’ and ‘b’ are respectively: 6.1.5.3.1. coefficient ‘a’ = 0,97; 6.1.5.3.2. coefficient ‘b’ for normal, special, snow or temporary-use spare tyres



Category of use Passenger car tyres Commercial vehicle tyres Radial Bias Radial Bias Normal 1,04 1,08 1,04 1,07 Special — — 1,06 1,09 Snow 1,04 1,08 1,04 1,07 Temporary-use 1,04 1,08 — — 6.1.5.4. For snow tyres the outer diameter (Dmax) established in conformity with the above may be exceeded by 1 %. 6.2. Load/speed test requirement 6.2.1. The tyre must undergo a load/speed test carried out in accordance with the relevant procedure described in Appendix 7. 6.2.2. A tyre which, after undergoing the relevant load/speed test, does not exhibit any tread separation, ply separation, cord separation, chunking or broken cords is deemed to have passed the test. 6.2.3. The outer diameter of the tyre, measured six hours after the load/speed test, must not be more than 3,5 % greater than the outer diameter as measured before the test. 6.2.4. Where application is made for the approval of a type of commercial vehicle tyre the load/speed combinations given in the table in Appendix 8 apply and, the load/speed test prescribed in section 6.2.1 need not be carried out for load and speed values other than the nominal values. 6.2.5. Where application (see secton 6.13 of Annex 1, Appendix 1) is made for the type-approval of a type of commercial vehicle 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 Appendix 8, the load/speed test prescribed in section 6.2.1 must also be carried out on a second tyre of the same type at the additional load/speed combination. 6.2.6. Where a tyre manufacturer produces a range of tyres it is not considered necessary to carry out a load/speed test on every type of tyre in the range. Worst-case selection may be made, at the discretion of the approval authority. 6.3. Tread-wear indicators 6.3.1. In the case of passenger car tyres the tread of the tyre must include not less than six transverse rows of tread-wear indicators, approximately equally spaced and situated in the wide grooves in the central zone of the tread, which covers approximately three quarters of the tread width. The tread-wear indicators must be such that they cannot be confused with the rubber ridges between the ribs or blocks of the tread. 6.3.2. However, in the case of tyres of dimensions appropriate for mounting on rims of a nominal diamter of 12″ or less, four rows of tread-wear indicators are acceptable. 6.3.3. The tread-wear indicators must give visual warning when the depth of the corresponding tread grooves has been reduced to 1,6 mm with a tolerance of + 0,6/- 0 mm.

1.4. The tyre-and-wheel assembly is conditioned at test-room temperature for not less than three hours.

1.5. The tyre pressure is readjusted to that specified in section 1.2 or 1.3.

2. Carrying out the test

2.1. The tyre-and-wheel assembly is mounted on a test axle and pressed against the outer face of a smooth wheel 1,70 m ± 1 % or 2 m ± 1 % in diameter.

2.2. Apply to the test axle a load equal to 80 % of: 2.2.1. the maximum load rating equated to the load capacity index for tyres with speed symbols L to H inclusive: 2.2.2. the maximum load rating associated with a maximum speed of 240 km/h for tyres with speed symbol ‘V’ (see section 2.31.2 of Annex II).

2.3. Throughout the test the tyre pressure must not be corrected and the test load must be kept constant.

2.4. During the test the temperature in the test-room must be maintained at between 20 oC and 30 oC or at a higher temperature if the manufacturer agrees.

2.5. The test is carred out without interruption in conformity with the following particulars: 2.5.1. time taken to pass from zero speed to initial test speed: 10 minutes; 2.5.2. initial test speed: prescribed maximum speed for the type of tyre, less 40 km/h in the case of the smooth wheel having 1,70 m ± 1 % in diameter or less 30 km/h in the case of the smooth wheel having 2 m ± 1 % in diameter; 2.5.3. successive speed increments: 10 km/h; 2.5.4. duration of test at each speed step except the last: 10 minutes; 2.5.5. duration of test at last speed step: 20 minutes; 2.5.6. maximum test speed: prescribed maximum speed for the type of tyre, less 10 km/h in the case of the smooth wheel having 1,7 m ± 1 % in diameter or equal to prescribed maximum speed in the case of the smooth wheel having 2 m ± 1 % in diameter.

3. Equivalent test methods

If a method other than that described in section 2 is used, its equivalence must be demonstrated.

PART B: COMMERCIAL VEHICLE TYRES ( 15 )

1. Preparing the tyre

1.1. Mount a new tyre on the test rim specified by the manufacturer pursuant to section 6.11 of Appendix 1 to Annex I.

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 specified by the tyre manufacturer, pursuant to section 6.14 of Appendix 1 to Annex I.

1.4. Condition the tyre and wheel assembly at test room temperature for not less than three hours.

ANNEX IV

REQUIREMENTS FOR VEHICLES WITH REGARD TO THE FITTING OF THEIR TYRES

1. DEFINITIONS

2. For the purpose of this Directive:

2.1. ‘approval of a vehicle’ means the approval of a vehicle type with regard to its tyres, including temporary-use spare tyres;

2.2. ‘vehicle type’ means a range of vehicles which do not differ significantly, at least as regards each variant of the vehicle type, in such essential aspects as would affect the tyre size designation, the speed category symbol or the load capacity index:

2.3. ‘wheel’ means a complete wheel consisting of a rim and a wheel disc;

2.4. ‘temporary-use spare wheel’ means a wheel different from one of the normal wheels on the vehicle type;

2.5. ‘unit’ means an assembly of a wheel and tyre;

2.6. ‘normal unit’ means a unit which is capable of being fitted to the vehicle for normal operation;

2.7. ‘spare unit’ means a unit which is intended to be exchanged for a normal unit in case of malfunction of the latter. A ‘spare unit’ may be either of the following: 2.7.0. ‘normal spare unit’, which is a unit that conforms to the normal unit of the vehicle type; 2.7.1. ‘temporary-use spare unit’, which is a unit that differs from the normal units of the vehicle type with regard to their principal characteristics (e.g. their tyre-size designation, functional dimensions, conditions of use or structure). It is intended for temporary use under restricted conditions. Temporary-use spare units may be of the following categories: 2.7.1.1. category 1 a unit consisting of a wheel which conforms to a wheel of a normal unit and a tyre which has principal characteristics (e.g. dimensions, structure) different to the normal tyre; 2.7.1.2. category 2 a unit consisting of a wheel and a tyre both having principal characteristics different to the normal unit and intended to be carried on the vehicle with the tyre inflated to the pressure specified for temporary use; 2.7.1.3. category 3 a unit consisting of a normal wheel and a tyre having principal characteristics different to a normal tyre and intended to be carried on the vehicle with the tyre folded and not inflated; 2.7.1.4. category 4 a unit consisting of a wheel and tyre both having principal characteristics different to a normal unit and intended to be carried on the vehicle with the tyre folded and not inflated;

2.8. ‘maximum mass’ means the maximum value stated by the vehicle manufacturer to be technically permissible for the vehicle;

2.9. ‘maximum axle load’ means the maximum value stated by the vehicle manufacturer to be technically permissible for the total vertical force between the contact surfaces of the tyres of the axle in question and the ground and resulting from the part of the vehicle mass supported by that axle. The sum of the axle loads may be greater than the value corresponding to the maximum mass of the vehicle;

2.10. ‘functional dimensions’ means dimensions derived from the size designation of the wheels and/or tyres (e.g. diameter, width, aspect ratio) and from the mounting of the unit to the vehicle (e.g. wheel offset);

2.11. ‘maximum design speed’ means the maximum speed approved for the vehicle type inclusive of the tolerance allowed for the conformity checks of the series production.

3. REQUIREMENTS FOR VEHICLES WITH REGARD TO THE FITTING OF THEIR TYRES

3.1. General

▼M1

3.1.1. Subject to the provisions of section 3.7.4., every tyre fitted to a vehicle, including where applicable any spare, must bear the EC type-approval mark(s) as specified in section 4 of Annex I or the type-approval mark indicating compliance with UN/ECE Regulations Nos 30 or 54. UN/ECE type-approval marks are considered to be equivalent only to the EC type-approval marks granted pursuant to Annex II.

▼B

3.2. Tyre fitment

3.2.1. All of the tyres fitted to a vehicle, excluding any temporary use spare, must have the same structure (see Annex II section 2.3).

3.2.2. All of the tyres fitted to one axle must be of the same type (see Annex II section 2.1).

3.2.3. The space in which the wheel revolves must be such as to allow unrestricted movement when using the maximum permissible size of tyres within the suspension and steering constraints provided by the vehicle manufacturer.

3.3. Load capacity

3.3.1. Subject to the provisions of section 3.7, the maximum load rating (see Annex II section 2.31) of every tyre, including a spare tyre (if provided) with which a vehicle is fitted is: 3.3.1.1. in the case of a vehicle fitted with tyres of the same type in single formation: at least equal to half of the maximum axle load (see section 2.9) for the most heavily loaded axle, as declared by the manufacturer of the vehicle; 3.3.1.2. in the case af a vehicle fitted with tyres of more than one type, in single formation: at least equal to half of the maximum axle load (see section 2.9), as declared by the manufacturer of the vehicle, in respect of the relevant axle; 3.3.1.3. in the case of a vehicle fitted with passenger car tyres in dual (twin) formation: at least equal to 0,27 times the maximum axle load, as declared by the manufacturer of the vehicle, in respect of the relevant axle; 3.3.1.4. in the case of axles fitted with commercial vehicle tyres in dual (twin) formation: at least equal to 0,25 times, with reference to the load capacity index for dual application, the maximum axle load as declared by the manufacturer of the vehicle, in respect of the relevant axle.

3.4. Speed capacity

3.4.1. Every tyre with which a vehicle is normally fitted must have a speed category symbol (see Annex II section 2.29) compatible with the maximum design speed of the vehicle (as declared by the vehicle manufacturer) or the applicable load/speed combination (see Annex II section 2.30).

3.4.2. The above specification does not apply: 3.4.2.1. in the case of temporary use spare units for which section 3.8 applies; 3.4.2.2. in the case of vehicles normally equipped with ordinary tyres and occassionally supplied with snow tyres. However, in this case the speed category symbol of the snow tyres must correspond to a speed either greater than the maximum design speed of the vehicle (as declared by the vehicle manufacturer) or not less than 160 km/h (or both). If, nevertheless, the maximum design speed of the vehicles (as declared by the vehicle manufacturer) is greater than the speed corresponding to the speed category symbol of the snow tyres a maximum speed warning label, specifying the maximum speed capability of the snow tyres, must be displayed inside the vehicle in a prominent position readily visible to the driver.

3.5. Spare tyre

3.5.1. In the case where a vehicle is provided with a spare wheel its tyre must be: 3.5.1.1. the same type as one of the tyres fitted to or approved for the vehicle, or 3.5.1.2. a temporary-use spare tyre of a type suitable for use on the vehicle, in any position. However, no vehicle other than a vehicle of category M1 ay be fitted with a temporary-use spare tyre.

3.5.2. Every vehicle provided with a temporary-use spare unit must be provided with supplementary information clearly and permanently displayed on the temporary-use spare unit or on the vehicle near the spare unit or in the driver's handbook. At least the following information must be given: 3.5.2.1. an instruction to drive with caution when the temporary-use spare unit is fitted, and to install a normal unit as soon as possible; 3.5.2.2. a statement that operation of the vehicle is not permitted with more than one temporary-use spare unit fitted at the same time; 3.5.2.3. a clear indication of the inflation pressure specified by the vehicle manufacturer for the tyre of the temporary-use spare unit; 3.5.2.4. for vehicles equipped with category 3 or category 4 temporary-use spare units, a description of the procedure for inflating the tyre to the pressure specified for temporary use by means of the device referred to in section 3.6;

3.6. Inflating device of temporary-use spare unit:

3.6.1. if the vehicle is equipped with a category 3 or category 4 temporary-use spare unit, a device must be provided on the vehicle which permits the tyre to be inflated to the pressure specified for temporary use within a maximum of five minutes.

3.7. Special cases

3.7.1. In the case of trailers of categories 01 and 02 with operating speeds restricted to 100 km/h or less fitted with passenger car tyres in single formation, the maximum load rating of every tyre must be at least equal to 0,45 times the maximum mass for the most heavily loaded axle, as declared by the manufacturer of the trailer. For tyres in dual (twin) formation this factor is 0,24.

3.7.2. In the case of some special vehicles fitted with commercial vehicle tyres, the table ‘Variation of Load Capacity with Speed’ (see section 2.30 and Appendix 8 to Annex II) is not to be applied. In those cases the tyre maximum load ratings to check against the maximum axle loads (see sections 3.3.1.2 and 3.3.1.4 of this Annex) are determined by multiplying the load corresponding to the load capacity index by an appropriate coefficient which is related to the type of vehicle and its use rather than to the maximum design speed of the vehicle. In such cases section 3.4.1 of this Annex does not apply. The appropriate cofficients are as follows: 3.7.2.1. 1,10 in the case of vehicles of category M3 when the vehicle is carrying standing passengers and the operating speed does not exceed 60 km/h. However, for operational reasons Member States may allow the operating speed to be increased to 80 km/h; 3.7.2.2. 1,15 in the case of such vehicles (M3) if they are intended for use only on urban routes with frequent stops; 3.7.2.3. 1,10 in the case of public utility vehicles of category N used at slow speeds over short distances in urban and suburban applications such as road sweepers or refuse collectors.

3.7.3. When a motor vehicle of category M1 is towing a trailer, the additional load imposed at the trailer coupling device may cause the tyre maximum load ratings to be exceeded, but not by more than 15 %, provided that the operating speed is restricted to 100 km/h or less and the inflation pressure increased by at least 0,2 bar is applied.

3.7.4. In the case of a vehicle which is fitted with tyres which are not passenger car tyres nor commercial vehicle tyres due to special conditions of use (e.g. agricultural tyres, industrial truck tyres, motor cycle tyres) the requirements of Annex II do not apply provided that the approval authority is satisfied that the tyres fitted are suitable for the operating conditions of the vehicle.

3.8. Specifications for temporary-use spare units

3.8.1. Every temporary-use spare tyre must have a speed category at least equal to 120 km/h (speed category symbol L).

3.8.2. When fitted to the vehicle for temporary use the outward facing surface of the wheel must exhibit a distinctive colour or colour pattern which is clearly different from the colour(s) of the normal units. If it is possible to attach a wheel cover to the temporary-use spare unit the distinctive colour or colour pattern must not be obscured by this wheel cover.

3.8.3. A maximum speed warning symbol must be permanently displayed on the outer face of the wheel in a prominent position and in accordance with the diagram below:
