2.4. "Tyre" means a pneumatic tyre, being a reinforced flexible envelope that is provided with,
or forms in conjunction with the wheel on which it is mounted, a continuous, essentially
toroidal, closed chamber containing a gas (usually air) or a gas and liquid, that is intended
normally to be used at a pressure greater than atmospheric pressure. It may be a:
2.4.1. "Normal tyre" being a tyre that is suitable for all normal, on-road, conditions of use;
2.4.2. "Temporary use spare tyre" being a tyre that is specifically designed to be different from a
normal tyre and intended only for temporary use under restricted driving conditions;
2.4.3. "Run flat tyre" or "Self supporting tyre" describes a pneumatic tyre structure provided
with any technical solutions (for example, reinforced sidewalls, etc.) allowing the pneumatic
tyre, mounted on the appropriate wheel and in the absence of any supplementary
component, to supply the vehicle with the basic tyre functions, at least, at a speed of
80 km/h (50 mph) and a distance of 80 km when operating in flat tyre running mode;
2.4.4. "Run flat system" or "Extended mobility system" describes an assembly of specified
functionally dependant components, including a tyre, which together provide the specified
performance granting the vehicle with the basic tyre functions, at least, at a speed of
80 km/h (50 mph) and a distance of 80 km when operating in flat tyre running mode.
2.5. "Flat tyre running mode" describes the state of tyre, essentially maintaining its structural
integrity, while operating at an inflation pressure between 0 and 70 kPa.
2.6. "Basic tyre function" means the normal capability of an inflated tyre in supporting a given
load up to a given speed and transmitting the driving, the steering and the braking forces to
the ground on which it runs.
2.7. "Tyre size designation" means a combination of figures that uniquely identify the
geometric size of the tyre, comprising the nominal section width, the nominal aspect ratio
and the nominal diameter. Precise definitions of these features may be found in
Regulation No. 30.
2.8. "Tyre structure" means the technical characteristics of the tyre's carcass. This may be
bias ply (diagonal or cross ply), bias-belted, radial ply or run flat tyre as further defined in
Regulation No. 30.
2.9. "Standard spare unit" means an assembly of a wheel and tyre identical in terms of wheel
and tyre size designations, wheel offset and tyre structure to that fitted in the same axle
position and to the particular model or version of the vehicle for normal operation. It
includes the case of a wheel that is produced from a different material, for example, steel
instead of aluminium alloy, that may use different wheel fixing nut or bolt designs but which
is otherwise identical to the wheel intended for normal operation.

3.3. A vehicle representative of the vehicle type to be approved shall be submitted to the type
approval authority or the technical service responsible for conducting the approval tests.
3.4. The competent authority shall verify the existence of satisfactory arrangements for ensuring
effective control of the conformity of production before type-approval is granted.

4.1. If the vehicle submitted for approval pursuant to this Regulation meets the requirements of
Paragraph 5 below, approval of this vehicle type shall be granted.
4.2. An approval number shall be assigned to each type-approval. Its first two digits (at
present 01 corresponding to the 01 series of amendments) 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 may not assign
the same number to another type of vehicle. However, variants of a model range which are
in separate categories with respect to the criteria of Paragraph 2.2. may be covered by the
same type-approval, provided that the results of the tests described in Paragraph 5.2. do not
show major differences.

Regulation shall be communicated to the Parties to the Agreement which apply this
Regulation by means of a form conforming to the model in Annex 1 to this Regulation.
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 consisting of:
4.4.1. a circle surrounding the Letter "E" followed by the distinguishing number of the country
which 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.
4.5. If the vehicle conforms to a vehicle type-approved, under one or more Regulations annexed
to the Agreement, in the country which granted approval under this Regulations, the symbol
prescribed in Paragraph 4.4.1. need not be repeated; in such a case, the Regulation and
approval numbers and the additional symbols for all the Regulations under which approval
has been granted in the country which granted approval under this Regulation shall be
placed in vertical columns to the right of the symbol prescribed in Paragraph 4.4.1.

In the case of vehicles intended to be sold in countries using imperial units of measurement,
