RADIAL TYRE HAVING AN IMPROVED BELT STRUCTURE REINFORCED WITH MONOFILAMENTS

The invention relates to a radial tyre, in particular for a private passenger vehicle or van, having a lightweight belt structure (10) comprising a multilayer composite laminate (10a, 10b, 10c) of specific construction, including: a first layer (10a) of rubber (C1) reinforced with heat-shrinking circumferential textile reinforcements (110) in the form of monofilaments or monofilament assemblies, e.g. of nylon or polyester, said first layer being mounted radially (in direction Z) on two other layers (10b, 10c) of rubber (C2, C3 respectively) reinforced with steel monofilaments (120, 130) and all or some of the monofilaments in each respective layer or row being arranged along axial direction Y in a plurality of successive dense series of monofilaments, characterised by an average intra-series distance, denoted W1, between successive monofilaments inside a series, which is less than the average inter-series distance, denoted W2, between successive series.
