Abstract
This invention relates generally to an improved design that provides better hydroplaning performance for a tire, and, more specifically, to a tire that has a variable pressure shear band located below its tread that provides increased structural stiffness to the tire, helping the tire to resist deformation when the tire encounters water, thereby decreasing the tendency of the tire to hydroplane. Advantageously, the variable pressure shear band can improve the hydroplaning performance and rolling resistance simultaneously without degrading wear performance.
