VEHICLE TYRES (manufacture, repairing B 29); TYRE INFLATION; TYRE CHANGING; CONNECTING VALVES TO INFLATABLE ELASTIC BODIES IN GENERAL; DEVICES OR ARRANGEMENTS RELATED TO TYRES (testing of tyres G 01 M 17/02) [5]

Notes

(1)

In this subclass, the following term is used with the meaning indicated:

–

"tyre" means a separate ground-engaging, continuous element outside the periphery of the wheel rim and includes the tyre casing, cover, or jacket and any insert, e.g. inner tube. In group B 60 C 29/00, relating to connection of valves, the term "tyre" also includes inflatable elastic bodies other than tyres or inner tubes.

(2)

Attention is drawn to the Note following the title of class B 60.

Tyres characterised by the chemical composition or the physical arrangement or mixture of the composition [4]

Note

Tyres characterised by the compositions only, i.e. having no significant tyre structure, are classified only with the compositions, e.g. in C 08 K, C 08 L. [4]

Note

When classifying in this group, classification is also made in subclass B 32 B insofar as any layered product is concerned. [4]

Carcasses

the reinforcing cords of each carcass ply arranged in a substantially parallel relationship
