Abstract

The invention comprises an improved non-pneumatic tire, and particularly a shear layer for a non-pneumatic tire wherein the shear layer comprises an elastomeric composition that includes a metal salt of a carboxylic acid. The shear layer preferably comprises a dienic elastomeric composition that includes a metal salt of a carboxylic acid. In one embodiment of the invention, the metal salt of the carboxylic acid is zinc diacrylate or zinc dimethacrylate. In one embodiment of the invention, the metal salt of the carboxylic acid is zinc diacrylate or zinc dimethacrylate, and a peroxide curative agent is employed.
