2. Definitions
For the purposes of this Regulation:
2.1. "Vehicle type with regard to the installation of its tyres" means vehicles which do not
differ in such essential respects as the types of tyres, minimum and maximum tyre size
designations, wheel dimensions and off-sets as well as speed and load capabilities suitable
for fitment, and the characteristics of the wheel guards;
2.2. Tyres shall be classified as follows:
(a)
(b)
Class C1 tyres – tyres designed primarily for vehicles of Categories M , N , O and
O ;
Class C2 tyres – tyres designed primarily for vehicles of Categories M , M , N, O
and O with a load capacity index in single formation ≤ 121 and the speed category
symbol ≥ 'N';
2.2.1. "Type of tyre" means a range of tyres which do not differ in the following essential
characteristics:
(a)
(b)
(c)
The tyre Class: C1 or C2, as described in Paragraph 2.2.; and
In the case of Class C1 tyres, the characteristics of a type of pneumatic tyre as
defined in Paragraph 2.1. of Regulation No. 30;
In the case of Class C2 tyres, the characteristics of a type of pneumatic tyre as
defined in Paragraph 2.1. of Regulation No. 54.

2.17. "Load capacity index" means a number associated to the maximum load rating of the tyre
in relation to the definition in Paragraph 2.30. of Regulation No. 30 for Class C1 tyres and
Paragraph 2.27. of Regulation No. 54 for Class C2 tyres.
2.18. "Maximum load rating" means the maximum mass which a tyre can carry when operated
in conformity with requirements governing utilisation specified by the tyre manufacturer.
3. APPLICATION FOR APPROVAL
3.1. The application for approval of a vehicle type with regard to the installation of its tyres shall
be submitted by the vehicle manufacturer or by his authorized representative.
3.2. It shall be accompanied by the documents mentioned below in triplicate and include the
following particular:
3.2.1. A description of the vehicle type with regard to the items mentioned in Paragraph 5.
3.3. A vehicle representative of the vehicle type to be approved, or a simulation tool representing
the vehicle type to be approved shall be submitted to the Technical Service conducting the
approval tests.
4. APPROVAL
4.1. If the vehicle type submitted for approval pursuant to this Regulation meets the
requirements of Paragraph 5, approval of that vehicle type shall be granted.
4.2. An approval number shall be assigned to each vehicle type approved; its first two digits (00
for the regulation in its initial form) shall indicate the series of amendments incorporating the
most recent major technical amendments made to the regulation at the time of issue of the
approval. The same Contracting Party shall not assign the same number to another vehicle
type with regard to the installation of its tyres.
4.3. Notice of approval or of refusal or withdrawal of approval pursuant to this Regulation shall
be communicated to the Contracting Parties to the Agreement applying this Regulation by
means of a form conforming to the model in Annex 1 and photographs and/or plans supplied
by the applicant being in a format not exceeding A4 (210 × 297 mm), or folded to that
format, and on an appropriate scale.
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 which
has granted approval;
4.4.2. the number of this Regulation, followed by the letter "R", a dash and the approval number to
the right of the circle prescribed in Paragraph 4.4.1.

5.2.2.1.2. 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.
5.2.2.1.3. 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.
5.2.2.1.4. In the case of axles fitted with tyres of Class C2 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.
5.2.2.2. The maximum load rating of a tyre is determined as follows:
5.2.2.2.1. In the case of tyres of Class C1, the "maximum load rating" as referred to in
Paragraph 2.34. of Regulation No. 30 is taken into account.
5.2.2.2.2. In the case of tyres of Class C2, the "table load-capacity variation with speed" as referred to
in Paragraph 2.29. of 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.
5.2.2.3. The manufacturer shall provide in the vehicle owner's handbook, or by any other
communication means in the vehicle the necessary information about replacement tyres
load capacity.
5.2.3. Speed Capacity
5.2.3.1. Every tyre with which the vehicle is normally fitted shall bear a speed category symbol.
5.2.3.1.1. 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 Regulation No. 30.
5.2.3.1.2. In the case of tyre of Class C2, 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 2.29. of
Regulation No. 54.
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.

5.2.5.2. Every vehicle provided with a temporary-use spare unit or run flat tyres shall comply with the
technical and transitional provisions of Regulation No. 64 with respect to the requirements
concerning the equipment of vehicles with temporary-use spare units and run flat tyres.
If specific precautions have to be taken in order to fit a temporary-use spare unit to the
vehicle (e.g. temporary use spare unit is only to be fitted on the front axle and therefore a
front standard unit must first be fitted on the rear axle in order to address a malfunction of a
rear standard unit) this shall be stated clearly in the vehicle owner’s handbook or any other
communication means in the vehicle, and compliance with the appropriate aspects of
Paragraph 5.2.1.3. of this Regulation shall be verified.
6. MODIFICATION OF VEHICLE TYPE AND EXTENSION OF APPROVAL
6.1. Every modification to an existing vehicle type shall be notified to the Type Approval
Authority which approved the vehicle type. The Type Approval Authority shall then either:
(a)
(b)
Decide, in consultation with the manufacturer, that a new type approval is to be
granted; or
Apply the procedure contained in Paragraph 6.1.1. (Revision) and, if applicable, the
procedure contained in Paragraph 6.1.2. (Extension).
6.1.1. Revision
6.1.2. Extension
When particulars recorded in the information documents of Annex 1 have changed and the
Type Approval Authority considers that the modifications made are unlikely to have an
appreciable adverse effect and that, in any case, the vehicle still complies with the
requirements, the modifications shall be designated a "revision";
In such a case, the Type Approval Authority shall issue the revised pages of the information
documents of Annex 1 as necessary, marking each revised page to show clearly the nature
of the modification and the date of re-issue. A consolidated, updated version of the
information documents of Annex 1, accompanied by a detailed description of the
modification, shall be deemed to meet this requirement.
The modification shall be designated an "extension" if, in addition to the change of the
particulars recorded in the information documents of Annex 1,
(a)
(b)
(c)
Further inspections or tests are required; or
Any information on the communication document (with the exception of its
attachments) has changed; or
Approval to a later series of amendments is requested after its entry into force.
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.
