Definitions

  • the width of the circumferential belt layer is set to 70% or more of the cross-sectional width of the tire, and the number of layers in the center portion CNT of the circumferential belt layer is made smaller than the number of layers in the shoulder portion SHO.
  • the inclined belt layer 3 is disposed only in a region that is less than 30% of the width W4b of the circumferential belt layer 4b, the effect of preventing belt breakage when riding over the protrusion may not be sufficiently exhibited.
  • the circumferential belt layers 4b and 4c are disposed in a region of 70% or more of the width W4b of the circumferential belt layer 4b (that is, the shoulder portion SHO), the inclined belt layer 3 is the circumferential belt layer 4b. If it is disposed in an area of 60% or less of the width W4b, the effect of preventing the belt from breaking when the protrusion is overridden can be sufficiently exhibited.

Abstract

L'invention concerne un pneumatique présentant une meilleure performance anti-usure irrégulière et une meilleure performance anti-usure. Ledit pneumatique est muni d'une ceinture et d'une bande de roulement, la ceinture et la bande de roulement étant formées en agençant séquentiellement : une carcasse toroïdale qui s'étend entre une paire de tringles; une couche de ceinture inclinée agencée radialement sur l'extérieur de la carcasse et formée en recouvrant les tringles avec du caoutchouc, les tringles s'étendant à l'oblique par rapport à la direction circonférentielle du pneumatique; des couches de ceinture circonférentielles qui sont formées en recouvrant les tringles avec du caoutchouc, les tringles s'étendant dans la direction circonférentielle du pneumatique; et des couches de ceinture transversales qui sont formées en recouvrant les tringles avec du caoutchouc, les tringles s'étendant dans une direction oblique par rapport à la direction circonférentielle du pneumatique et les tringles des différentes couches se croisant les unes avec les autres. La couche de ceinture inclinée est agencée au niveau d'au moins une section centrale. La largeur des couches de ceinture circonférentielles est supérieure ou égale à 70 % de la largeur de la section transversale du pneumatique. Le nombre de couches des couches de ceinture circonférentielles au niveau de la section centrale est inférieur au nombre de couches de cette dernière au niveau des sections d'épaulement.
