摘要：
An article intended to come into contact with the ground, and the article comprising a laminate comprising at least two superposed portions comprising: a first portion (FP) made of a first rubber composition (FC); and a second portion (SP) made of a second rubber composition (SC), and the SP positioned farther from the ground than the FP; wherein the amount in phr of the reinforcing filler in the SC is lower than that in the FC; wherein the second rubber composition (SC) is such that the reinforcing filler predominately comprises a reinforcing inorganic filler; wherein the ratio of the amount in phr of the plasticizing agent to the reinforcing filler in the SC is higher than that in the FC; and wherein the average glass transition temperature of combination of the elastomer matrix and the plasticizing agent in the SC is higher than that in the FC.
