1.1 - Retreated tyres for commercial vehicles and their trailers;

1.2 - Retreated tyres with a speed capability below 120 km/h or above 240 km/h;

1.3 - Tyres for cycles and motorcycles;

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

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

1.6 - Tyres designed for the equipment of cars produced prior to 1939;

1.7 - Tyres designed exclusively for competition or off road use and marked accordingly;

1.8 - Tyres designated as «T type» temporary use spares.

2.2 - «Structure» of a pneumatic tyre 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 90% 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 stabilized by a belt, comprising two of more layers of substantially inextensible cord material laid at alternate angles close to those of the carcass;
