Abstract: Disclosed herein are tire tread rubber compositions comprising a specified elastomer component, reinforcing silica filler, a combination of specified hydrocarbon resins, liquid plasticizer, and a cure package. The elastomer component includes styrene-butadiene rubber; polybutadiene; and natural rubber, polyisoprene, or a combination thereof. Also disclosed are methods for providing a tire tread having improved dry handling and wet traction performance.

Abstract: A system and method are provided for efficiently estimating vehicle tire wear. Vehicle kinetics (first) data are provided via one or more sensors associated with the vehicle and/or at least one associated tire. The vehicle kinetics data are locally processed to compress or otherwise generate second data as a reduced subset thereof, said second data representative of the first data and comprising any one or more predetermined wear-specific features extracted therefrom. The second data are selectively transmitted via a communications network to a remote computing system, which processes the second data to estimate a wear characteristic for the at least one tire. Alternatively, the second data processed to generate third data as a reconstruction of the first data, and the third data and the any one or more extracted features are processed to estimate a wear characteristic for the at least one tire.
