2.3. "Wheel" means a complete wheel consisting of a rim and a wheel disc;
2.3.1. "Wheel size designation" means a designation comprising at least the nominal rim
diameter, the nominal rim width and the rim profile;
2.3.2. "Wheel offset" means the distance from the hub abutment face to the centre line of the rim.
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 80km/h
(50mph) and a distance of 80km 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 80km/h
(50mph) and a distance of 80km 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 70kPa.
