THE EUROPEAN COMMISSION,
Having regard to the Treaty on the Functioning of the European Union,
Having regard to Regulation (EC) No 661/2009 of the European Parliament and of the Council of 13 July 2009 concerning type-approval requirements for the general safety of motor vehicles, their trailers and systems, components and separate technical units intended therefor, and in particular Article 14(1)(a) thereof,
OJ L 200, 31.7.2009, p. 1.
Whereas:
(1) Regulation (EC) No 661/2009 is a separate Regulation for the purposes of the type-approval procedure provided for by Directive 2007/46/EC of the European Parliament and of the Council of 5 September 2007 establishing a framework for the approval of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles (Framework Directive).
OJ L 263, 9.10.2007, p. 1.
(2) Regulation (EC) No 661/2009 repeals Council Directive 92/23/EEC of 31 March 1992 relating to tyres for motor vehicles and their trailers and to their fitting. The requirements set out in that Directive should be carried over to this Regulation and, where necessary, adapted to the development of scientific and technical knowledge.
OJ L 129, 14.5.1992, p. 95.
(3) The scope of this Regulation should be in line with that of Directive 92/23/EEC. The Regulation should therefore cover vehicles of categories M, N and O.
(4) Regulation (EC) No 661/2009 lays down basic requirements for the type-approval of motor vehicles with regard to the installation of tyres. Therefore, it is necessary to set out the specific procedures, tests and requirements for such type-approval to ensure that the tyres used on a vehicle are appropriate for the load, speed and use characteristics of that vehicle.

ANNEX II Requirements for vehicles with regard to the installation of their tyres

1. GENERAL REQUIREMENTS
1.1. Subject to the provisions of paragraph 5.4, every tyre fitted to a vehicle, including where applicable any spare tyre, shall meet the requirements of Regulation (EC) No 661/2009 and its implementing measures.

2. TYRE FITMENT
2.1. All tyres normally fitted to the vehicle, thus excluding any temporary-use spare unit, shall have the same structure.
2.2. All of the tyres normally fitted to one axle shall be of the same type.
2.3. The space in which the wheel revolves shall be such as to allow unrestricted movement when using the maximum permissible size of tyres and rim widths, taking into account the minimum and maximum wheel off-sets, within the minimum and maximum suspension and steering constraints as declared by the vehicle manufacturer. This shall be verified by performing the checks with the largest and the widest tyres, taking into account the applicable dimensional tolerances (i.e. maximum envelope) related to the tyre size designation as specified in the relevant UNECE Regulation.
2.4. The technical service may agree to an alternative test procedure (e.g. virtual testing) to verify that the requirements of paragraph 2.3 of this Annex are met.

3. LOAD CAPACITY

3.1. Subject to the provisions of paragraph 5 of this Annex, the maximum load rating of every tyre as determined in paragraph 3.2 of this Annex, including a spare tyre (if provided), with which the vehicle is fitted shall be:
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 technically permissible maximum axle mass for the most heavily loaded axle, as declared by the manufacturer of the vehicle.
3.1.2. In the case of a vehicle fitted with tyres of more than one type, in single formation: at least equal to half of the technically permissible maximum axle mass as declared by the manufacturer of the vehicle, in respect of the relevant axle.
3.1.3. In the case of a vehicle fitted with tyres of class C1 in dual (twin) formation: at least equal to 0,27 times the technically permissible maximum axle mass, as declared by the manufacturer of the vehicle, in respect of the relevant axle.
3.1.4. In the case of axles fitted with tyres of class C2 or C3 in dual (twin) formation: at least equal to 0,25 times, with reference to the load capacity index for dual application, the technically permissible maximum axle mass as declared by the manufacturer of the vehicle, in respect of the relevant axle.

3.2. The maximum load rating of a tyre is determined as follows:
3.2.1. In the case of tyres of class C1, the ‘maximum load rating’ as referred to in paragraph 2.31 of UNECE Regulation No 30 is taken into account.
3.2.2. In the case of tyres of class C2 or C3, the ‘table load-capacity variation with speed’ as referred to in paragraph 2.29 of UNECE Regulation No 54 is taken into account, which shows, as a function of the load-capacity indices and nominal-speed-category symbols, the load variations which a pneumatic tyre can withstand taking into account the maximum design speed of the vehicle.
3.3. The relevant information shall be stated clearly in the vehicle owner’s handbook in order to ensure that suitable replacement tyres with an appropriate load capacity shall be fitted when necessary, once the vehicle has been put into service.

4. SPEED CAPACITY
4.1. Every tyre with which the vehicle is normally fitted shall bear a speed category symbol.
4.1.1. In the case of a tyre of class C1, the speed category symbol shall be compatible with the maximum vehicle design speed and shall take into account, in the case of tyres of speed categories V, W and Y, the maximum load rating as described in UNECE Regulation No 30.
4.1.2. In the case of a tyre of class C2 or C3, the speed category symbol shall be compatible with the maximum vehicle design speed and the applicable load/speed combination derived from the ‘table load-capacity variation with speed’ as described in paragraph 3.2.2 of this Annex.

4.2. The requirements of paragraphs 4.1.1 and 4.1.2 shall not apply in the following situations:
4.2.1. In the case of temporary-use spare units for which paragraph 6 of this Annex applies.
4.2.2. In the case of vehicles normally equipped with ordinary tyres and occasionally fitted with snow tyres (i.e. with the alpine or three-peaked mountain snowflake symbol marking) where in such a case the speed category symbol of the snow tyre shall correspond to a speed either greater than the maximum vehicle design speed or not less than 160 km/h (or both). However, if the maximum vehicle design speed is greater than the speed corresponding to the lowest speed category symbol of the fitted snow tyres, a maximum speed warning label, specifying the lowest value of the maximum speed capability of the fitted snow tyres, shall be displayed inside the vehicle in a prominent position readily and permanently visible to the driver. Other tyres with improved snow traction (i.e. with the M+S marking, but without the alpine or three-peaked mountain snowflake symbol marking) shall comply with the requirements of paragraphs 4.1.1 and 4.1.2 of this Annex.
4.2.3. In the case of vehicles equipped with professional off-road tyres with the POR marking. However, if the maximum vehicle design speed is greater than the speed corresponding to the lowest speed category symbol of the fitted special use tyres, a maximum speed warning label, specifying the lowest value of the maximum speed capability of the fitted special use tyres, shall be displayed inside the vehicle in a prominent position readily and permanently visible to the driver.
4.2.4. In the case of vehicles of categories M2, M3, N2 or N3 equipped with a speed limitation device (SLD) approved according to UNECE Regulation No 89 where in such a case the speed symbol of the tyres shall be compatible with the speed at which the limitation is set. However, if the vehicle manufacturer has foreseen that the maximum vehicle design speed is greater than the speed corresponding to the lowest speed category symbol of the fitted tyres, a maximum speed warning label, specifying the maximum speed capability of the tyres, shall be displayed inside the vehicle in a prominent position readily and permanently visible to the driver.
OJ L 158, 19.5.2007, p. 1.
4.2.5. In the case of vehicles of categories M1 or N1 equipped with an on-board system fulfilling a speed limitation function where in such a case the speed symbol of the tyres shall be compatible with the speed at which the limitation is set. However, if the vehicle manufacturer has foreseen that the maximum vehicle design speed is greater than the speed corresponding to the lowest speed category symbol of the fitted tyres, a maximum speed warning label, specifying the maximum speed capability of the tyres, shall be displayed inside the vehicle in a prominent position readily and permanently visible to the driver.
4.3. The relevant information shall be stated clearly in the vehicle owner’s handbook in order to ensure that suitable replacement tyres with an appropriate speed capacity shall be fitted when necessary, once the vehicle has been put into service.

5. SPECIAL CASES
5.1. In the case of trailers of categories O1 and O2, with a maximum vehicle design speed of 100 km/h or less and fitted with tyres of class C1 in single formation, the maximum load rating of every tyre shall be at least equal to 0,45 times the technically permissible maximum axle mass for the most heavily loaded axle, as declared by the manufacturer of the trailer. For tyres in dual (twin) formation this factor shall be at least equal to 0,24. In such cases a maximum operating speed warning label, specifying the maximum vehicle design speed, shall be permanently and durably affixed near the front coupling device of the trailer.
5.2. In the case of vehicles of categories M1 and N1, which are designed to be capable of towing a trailer, the additional load imposed at the trailer coupling device may cause the rear tyre maximum load ratings to be exceeded in case of class C1 tyres, but not by more than 15 %. In such a case, the vehicle owner’s handbook shall contain clear information and advice on the maximum permissible vehicle speed when towing a trailer, in any case not exceeding 100 km/h, and on the rear tyre pressure, at least 20 kPa (0,2 bar) above the tyre pressure(s) as recommended for normal use (i.e. without a trailer attached).

5.3. In the case of some special vehicles, as listed below, fitted with tyres of class C2 or C3, the ‘table load-capacity variation with speed’ as described in paragraph 3.2.2 of this Annex shall not be applied. In such a case, the tyre maximum load rating to check against the technically permissible maximum axle mass (see paragraphs 3.1.2 to 3.1.4) shall be 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 vehicle design speed, and the requirements of paragraphs 4.1.1 and 4.1.2 of this Annex shall not apply.
The appropriate coefficients shall be the following:
5.3.1. 1,15 in the case of a Class I or Class A vehicle (M2 or M3), as referred to in paragraphs 2.1.1.1 (Class I) and 2.1.2.1 (Class A) of UNECE Regulation No 107.
OJ L 255, 29.9.2010, p. 1.
5.3.2. 1,10 in the case of vehicles of category N which are specifically designed for use over short distances in urban and suburban applications, such as street and road sweepers or refuse collection vehicles, provided that the maximum vehicle design speed does not exceed 60 km/h.

5.4. In exceptional cases, where vehicles are designed for conditions of use which are incompatible with the characteristics of tyres of class C1, C2 or C3 and it is therefore necessary to fit tyres with different characteristics, the requirements of paragraph 1.1 of this Annex shall not apply, provided that all of the following conditions are met:
