1.1 - Retreaded tyres for private (passenger) cars and their trailers;

1.2 - Retreaded tyres with a speed capability below 80 km/h;

1.3 - Tyres for cycles and motorcycles;

1.4 - Tyres originally produced without speed symbols and or load indices;

1.5 - Tyres originally produced without type approval and without either an «E» or «e» mark.

2 - Definitions (see also figure in annex 9). - For the purpose of this Regulation:

2.1 - «Range of retreaded pneumatic tyres» means a range of retreaded pneumatic tyres as quoted in paragraph 4.1.4;

2.2 - «Structure» of a pneumatictyre» means the technical characteristics of the tyre's carcass. The following structures are distinguished in particular:

2.2.1 - «Diagonal» or «Bias ply» describes a pneumatic-tyre structure in which the ply cords extend to the beads and are laid at alternate angles substantially less than 90º to the centreline of the tread;

2.2.2 - «Bias belted» describes a pneumatic-tyre structure of diagonal (bias-ply) type in which the carcass is stabilised by a belt, comprising two or more layers of substantially inextensible cord material laid at alternate angles close to those of the carcass;

2.3 - «Category of use»:

2.3.1 - Normal tyre is a tyre intended for normal road use only;

2.3.2 - Special use tyre is a tyre intended for mixed use, both on and off road and or at restricted speed;

2.3.3 - Snow tyre is a tyre whose tread pattern, or tread pattern and structure, is primarily designed to ensure, in mud and fresh or melting snow, a performance better than that of a normal tyre. The tread pattern of a snow tyre generally consists of groove (rib) and solid block elements more widely spaced than on a normal tyre;

2.4 - «Bead» means the part of a pneumatic-tyre which is of such shape and structure as to fit the rim and hold the tyre on it;

2.5 - «Cord» means the strands forming the fabric of the plies in the pneumatic-tyre;

2.6 - «Ply» means a layer of «rubber» coated parallel cords;

2.7 - «Belt» applies to a radial ply or bias belted tyre and means a layer or layers of material or materials underneath the tread, laid substantially in the direction of the centreline of the tread to restrict the carcass in a circumferential direction;

2.8 - «Breaker» applies to a diagonal ply tyre and means an intermediate ply between the carcass and tread;

2.13 - «Sidewall» means the part of a pneumatic tyre between the tread and the area designed to be covered by the rim flange;

2.14 - «Lower area of tyre» means the area included between the line of maximum section width of the tyre and the area designed to be covered by the edge of the rim;

2.15 - «Tread groove» means the space between the adjacent ribs or blocks in the tread pattern;

2.16 - «Section width» means the linear distance between the outside of the sidewalls of an inflated pneumatic tyre, when fitted to the specified measuring rim, but excluding elevations due to labelling (marking), decoration or protective bands or ribs;

2.17 - «Overall width» means the linear distance between the outside of the sidewalls of an inflated pneumatic-tyre, when fitted to the specified measuring rim, and including labelling (marking), decoration or protective bands or ribs;

2.18 - «Section height» means a distance equal to half the difference between the outer diameter of the tyre and the nominal rim diameter;

2.19 - «Nominal aspect ratio» means one hundred times the number obtained by dividing the number expressing the nominal section height by the number expressing the nominal section width, both dimensions being in the same units;

2.20 - «Outer diameter» means the overall diameter of an inflated, newly retreaded tyre;

2.21 - «Tyre-size designation» means a designation showing:

2.21.3 - A conventional number «d» (the «d» symbol) denoting the nominal rim diameter of the rim and corresponding to its diameter expressed either by codes (numbers below 100) or in millimetres (numbers above 100). Numbers corresponding to both types of measurements may be used in the designation:

2.21.3.1 - The values of the «d» symbols expressed in millimetres are shown below:

2.22 - «Nominal rim diameter (d)» means the diameter of the rim on which a tyre is designed to be mounted;

2.23 - «Rim» means the support, either for a tyre-and-tube assembly or for a tubeless tyre, on which the tyre beads are seated;
