Abstract

a presente invenção se refere a um pneumático para veículos destinados a levar cargas pesadas cuja a banda de rodagem compreende uma composição à base de pelo menos uma matriz elastomérica que compreende um poliisopreno e um elastômero termoplástico estirênico saturado que compreende pelo menos um segmento rígido estirênico e pelo menos um segmento flexível diênico hidrogenado, uma carga reforçadora, um sistema de reticulação, o poliisopreno representando mais de 50 % da diferença entre a massa da matriz elastomérica e a massa do elastômero termoplástico saturado, o elastômero termoplástico estirênico saturado representa no máximo 50 % em massa da matriz elastomérica. tal pneumático apresenta uma resistência à propagação de fissura melhorada.The present invention relates to a vehicle tire for carrying heavy loads whose tread comprises a composition based on at least one elastomeric matrix comprising a polyisoprene and a saturated styrene thermoplastic elastomer comprising at least one rigid styrenic segment and At least one hydrogenated diene flexible segment, a reinforcing charge, a crosslinking system, polyisoprene representing more than 50% of the difference between the elastomeric matrix mass and the saturated thermoplastic elastomer mass, the saturated styrene thermoplastic elastomer represents a maximum of 50%. mass of the elastomeric matrix. such a tire exhibits improved crack resistance.
