TYRE COMPRISING A LAYER OF CIRCUMFERENTIAL REINFORCING ELEMENTS

摘要

The invention relates to a tire comprising a crown reinforcement formed of at least two working crown layers of reinforcing elements, and of at least one layer of circumferential reinforcing elements. According to the invention, the reinforcing elements of the said at least two working crown layers have a diameter less than 1.1 mm and satisfy the following relationships: (Fr×4 cos2 α)/(P×0.75×Ø)<5, Fr1/(P1×sin|α1|)≧1.2 Fr2/(P2×sin|α2|).
