Abstract

pneumático que compreende uma banda de rodagem que compreende pelo menos uma nervura central (411-413) e duas nervuras laterais (421-422) separadas por ranhuras circunferenciais (141-144), no qual uma primeira nervura lateral (421), adjacente à borda axial exterior da banda de rodagem e pelo menos uma (e de preferência cada uma delas) das nervuras centrais compreendem uma primeira porção (4211, 4111, 4121, 4131) da qual a largura axial excede 20 % da largura axial da nervura em questão e cuja profundidade é inferior àquela da nervura em questão, realizada em uma composição de borracha que compreende um elastômero e uma carga reforçadora majoritariamente constituída por negro de fumo, e uma segunda porção (4212, 4112, 4122, 4132) axialmente adjacente, realizada em uma composição de borracha que compreende um elastômero e uma carga reforçadora minoritariamente constituída por negro de fumo, no qual as composições de borracha que formam a segunda porção da primeira nervura lateral e a segunda porção da nervura central têm todas elas um valor de tan ¿0 que é inferior ao valor de tan ¿0 das composições de borracha que formam a primeira porção da primeira nervura lateral e a primeira porção da nervura central, os valores de tan ¿0 sendo medidos na temperatura de 0ºc e sob uma tensão de 0,7 mpa.
