摘要： A tread for a tire, the tread comprising a rubber composition that is based upon a cross-linkable elastomer composition, the cross-linkable elastomer composition comprising, per hundred parts by weight of rubber (phr), a high-Tg rubber being a highly unsaturated diene elastomer having a glass transition temperature of between −30° C. and 0° C., a low-Tg rubber being a highly unsaturated diene elastomer having a glass transition temperature of between −110° C. and −60° C. The high-Tg and the low-Tg elastomers are incompatible and this provides, among other advantages, improved snow traction of the tread when compared to tire treads having lower Tg.

The composition may further include between 60 phr and 130 phr of a plasticizing system made up of a plasticizing resin having a Tg of at least 25 °C and a plasticizing liquid. The rubber composition is cured with an ultra-efficient sulfur curing system having a sulfur to accelerator weight ratio adjusted between 0.02 and 0.2 to provide the rubber composition with an MA300/G* ratio of greater than 1.7, wherein the elongation modulus MA300 at 300 % is measured at 23 °C and the shear modulus G* is measured at 60 °C.

In an embodiment, a method for producing a material diffusion barrier on a tire comprises exposing a surface of the tire to a cationic solution to produce a cationic layer on the surface. The method further comprises exposing the cationic layer to an anionic solution to produce an anionic layer on the cationic layer, wherein a layer comprises the cationic layer and the anionic layer. The layer comprises the material diffusion barrier.
