Abstract

banda de rodagem de pneu e um pneu que tem a dita banda de rodagem, que faz com que seja possível demonstrar um nível de desempenho superior no gelo e na neve quando a banda de rodagem é completamente nova, e, em particular, o desempenho na neve, mantendo-se ao mesmo tempo o desempenho no molhado. a banda de rodagem de pneu de acordo com a presente invenção compreende: uma pluralidade de elementos de contato com o solo que são definidos por uma pluralidade de sulcos formados em uma superfície de contato com o solo em contato com uma superfície de pista quando o pneu está rolando, e que tem uma superfície superior que forma uma porção da superfície de contato com o solo; e uma pluralidade de reentrâncias pequenas que se abrem na superfície superior, são recuadas para dentro na direção radial do pneu, e não ficam em comunicação entre si, sendo que a profundidade h das reentrâncias pequenas está entre 0,15 mm e 1,5 mm quando a banda de rodagem é completamente nova, e a densidade projetada das reentrâncias pequenas (um valor obtido dividindo-se o comprimento projetado total lp (mm) das reentrâncias pequenas presentes na superfície superior dos elementos de contato com o solo, projetadas em um plano paralelo ao eixo geométrico de rotação do pneu e perpendicular à superfície superior, pela área de superfície (mm2) da superfície superior quando as pequenas reentrâncias não estão presentes, e multiplicando-se o resultado por 1.000) é 200 ou maior.
