wheels produced from a different material and which may use different wheel fixing nut or
bolt designs, but which is otherwise identical to the wheel intended for normal operation.

4.4. There shall be affixed, conspicuously and in a readily accessible place specified on the
approval form, to every vehicle conforming to a vehicle type approved under this Regulation,
an international approval mark conforming to the model described in Annex 3, consisting of:
4.4.1. a circle surrounding the Letter "E" followed by the distinguishing number of the country

case, the regulation and approval numbers and the additional symbols shall be placed in
vertical columns to the right of the symbol prescribed in Paragraph 4.4.1.
4.6. The approval mark shall be clearly legible and be indelible.
4.7. The approval mark shall be placed close to or on the vehicle data plate.
5. SPECIFICATIONS
5.1. General Requirements
5.1.1. Subject to the provisions of Paragraph 5.2.4.2., every tyre fitted to a vehicle, including where
applicable any spare tyre, shall meet the requirements of this Regulation.
5.1.2. Every tyre installed to a vehicle, including where applicable any spare tyre, shall fulfil the
technical requirements and respect the transitional provisions of Regulations Nos. 30, 54
and 117 as applicable.
5.2. Performance Requirements
5.2.1. Tyre Fitment
5.2.1.1. All tyres normally fitted to the vehicle, thus excluding any temporary-use spare unit, shall
have the same structure.
5.2.1.2. All of the tyres normally fitted to one axle shall be of the same type.
5.2.1.3. 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 UN Regulation.
5.2.1.4. The Technical Service and/or Type Approval Authorities may agree to an alternative test
procedure (e.g. virtual testing) to verify that the requirements of Paragraph 5.2.1.3. are met.

5.2.3.2. The requirements of Paragraphs 5.2.3.1.1. and 5.2.3.1.2. shall not apply in the following
situations:
5.2.3.2.1. In the case of temporary-use spare units for which Paragraph 5.2.5. of this Regulation
applies.
5.2.3.2.2. In the case of vehicles normally equipped with normal tyres and occasionally fitted with
snow tyres 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 160km/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.
5.2.3.2.3. In the case of vehicles equipped with special use tyres. 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.
5.2.3.2.4. In the case of vehicles 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 seed 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.
5.2.3.3. The manufacturer shall provide the necessary information about replacement tyres speed
capacity in the vehicle owner's handbook or by any other communication means in the
vehicle.
5.2.4. Special Cases
5.2.4.1. In the case of vehicles 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, or the other communication means referred to in
Paragraph 5.2.3.3., shall contain clear information and advice on the maximum permissible
vehicle speed when towing a trailer, in any case not exceeding 100km/h, and on the rear
tyre pressure, at least 20kPa (0.2bar) above the tyre pressure(s) as recommended for
normal use (i.e. without a trailer attached).
5.2.4.2. In exceptional cases, where vehicles are designed for conditions of use which are
incompatible with the characteristics of tyres of Class C1 or C2 and it is therefore necessary
to fit tyres with different characteristics, the requirements of Paragraph 5.1.1. of this
Regulation shall not apply, provided that all of the following conditions are met:
5.2.4.2.1. The tyres fulfil the technical requirements and respect the transitional provisions of either
Regulation No. 75 or Regulation No. 106; and
5.2.4.2.2. The type-approval authority and technical service are satisfied that the tyres fitted are
suitable for the operating conditions of the vehicle. The nature of the exemption and
motivation of acceptance shall be stated in the test report as well as on the communication
form of Annex 2.

6.2. Confirmation or refusal of approval, specifying the alterations, shall be communicated by the
procedure specified in Paragraph 4.3. above to the Contracting Parties to the Agreement
applying this Regulation. In addition, the index to the information documents and to the test
reports, attached to the communication document of Annex 1, shall be amended accordingly
to show the date of the most recent revision or extension.
6.3. The Type Approval Authority issuing the extension of approval shall assign a series number
to each communication form drawn up for such an extension.
7. CONFORMITY OF PRODUCTION
7.1. Procedures concerning conformity of production shall conform to the general provisions
defined in Article 2 and Appendix 2 to the Agreement (E/ECE/324-E/ECE/TRANS/505/Rev.2)
and meet the following requirements:
7.2. A vehicle approved pursuant to this Regulation shall be so manufactured as to conform to
the type approved by meeting the requirements of Paragraph 5.;
7.3. The Type Approval Authority which has granted the approval may at any time verify the
conformity of control methods applicable to each production unit. The normal frequency of
such inspections shall be once every two years.
8. PENALTIES FOR NON-CONFORMITY OF PRODUCTION
8.1. The approval granted in respect of a vehicle type pursuant to this Regulation may be
withdrawn if the requirements laid down in Paragraph 7. are not complied with.
8.2. If a Contracting Party withdraws an approval it had previously granted, it shall forthwith so
notify the other Contracting Parties applying this Regulation by sending them a
communication form conforming to the model in Annex 1 to this Regulation.
9. PRODUCTION DEFINITIVELY DISCONTINUED
If the holder of the approval completely ceases to manufacture a type of vehicle approved in
accordance with this Regulation, he shall so inform the authority which granted the
approval, which in turn shall forthwith inform the other Contracting Parties to the Agreement
applying this Regulation by means of a communication form conforming to the model in
Annex 1 to this Regulation.
10. NAMES AND ADDRESSES OF THE TECHNICAL SERVICES RESPONSIBLE FOR
CONDUCTING APPROVAL TESTS AND OF TYPE APPROVAL AUTHORITIES
The Contracting Parties to the Agreement applying this Regulation shall communicate to the
United Nations Secretariat the names and addresses of the Technical Services responsible
for conducting approval tests and of the Type Approval Authority which grant approval and
to which forms certifying approval or extension or refusal or withdrawal of approval are to be
sent.
