REGULATION NO. 64
(TEMPORARY USE SPARE UNIT, RUN FLAT TYRES, RUN FLAT-SYSTEM
AND TYRE PRESSURE MONITORING SYSTEM)
1. SCOPE
1.
This Regulation applies to the approval of vehicles of Category M and N
when
equipped with:
(a)
(b)
A temporary use spare unit; and/or
Run-flat tyres and/or a run-flat system.
2. DEFINITIONS
For the purposes of this Regulation, spare wheel and tyre substitute units in the form of
run-flat tyres or a run-flat system in a totally deflated condition, are to be treated as being
temporary-use spare units as defined in Paragraph 2.10. of the Regulation.
For the purposes of this Regulation:
2.1. "Approval of a vehicle" means the approval of a vehicle type with regard to its
temporary-use spare wheel and tyre unit.
2.2. "Vehicle type" means a category of vehicles which do not differ significantly in such
essential aspects as:
2.2.1. "Vehicle type with regard to its temporary-use spare unit":
2.2.1.1. The maximum axle loads of the vehicle, as defined in Paragraph 2.10;
2.2.1.2. The characteristics of the temporary-use spare wheel and tyre unit;
2.2.1.3. The method of drive (front wheel, rear wheel, four wheels);
2.2.1.4. The suspension;
2.2.1.5. The braking system;
2.2.1.6. The wheel size/tyre size;
2.2.1.7. The wheel offset.

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.
2.10. "Temporary-use spare unit" means an assembly of any wheel and tyre that is not
within that defined as a "Standard spare unit" in Paragraph 2.9. Temporary-use spare
units may be of the following types:
2.10.1. Type 1
2.10.2. Type 2
2.10.3. Type 3
2.10.4. Type 4
2.10.5. Type 5
An assembly in which the tyre is a temporary-use spare tyre as defined in
Paragraph 2.4.2.;
An assembly in which the wheel has a different offset from that of the wheel fitted in the
same axle position for normal operation of the vehicle;
An assembly in which the tyre is of a different structure from that fitted in the same axle
position for normal operation of the vehicle;
An assembly in which the tyre is a normal tyre as defined in Paragraph 2.4.1. but where
the size designation of the wheel or the tyre or both, differ from those of the wheel or tyre
fitted in the same axle position for normal operation of the vehicle;
An assembly in which a wheel and tyre unit as defined in Paragraph 2.4.3. or 2.4.4. is
fitted to the vehicle for normal, long term road use, but used in an emergency in a totally
deflated condition.
2.11. "Maximum mass" means the maximum value of the vehicle stated by the manufacturer
to be technically permissible (this mass may be higher than the "permissible maximum
mass" laid down by the national administration).
2.12. "Maximum axle load" means the maximum value, as indicated by the manufacturer, of
the total vertical force between the contact surfaces of the tyres or tracks of one axle and
the ground and resulting from the part of the vehicle mass supported by that axle; this
load may be higher than the "authorized axle load" laid down by the national
administration. The sum of the axle loads may be greater than the value corresponding
to the total mass of the vehicle.
2.13. "Run-Flat Warning System" describes a system which delivers information to the driver
that a tyre is operating in the flat tyre running mode.

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 affixed by the
manufacturer.
4.8. Annex 2 to this Regulation gives examples of approval marks.
