Abstract: The subject invention reveals a tire tread having a circumferential tread cap with circumferential grooves, wherein the tread cap rubber compound has a Shore A hardness from 45 to 75. Moreover, the tread comprises at least one circumferential groove reinforcement reinforcing at least a bottom portion of at least one of the grooves and comprising a groove reinforcement rubber compound, wherein the groove reinforcement rubber compound has a Shore A hardness from 70 to 100. The tread also comprises a circumferential tread base layer arranged radially inwards of the tread cap and comprising a tread base layer compound, wherein the tread base layer compound has a Shore A hardness from 15 to 60, and wherein the Shore A hardness of the tread cap compound is higher than the Shore A hardness of the tread base layer compound.

Abstract: A method for estimating a grip of a tire supporting a vehicle includes generating a first set of data from a tire-mounted sensor unit, generating a second set of data from the tire-mounted sensor unit and from data obtained from the vehicle, and generating a third set of data from data obtained from the vehicle and from the Internet. A grip estimation module is provided. The first, second and third sets of data are received in the grip estimation module. A friction probability distribution is calculated with the grip estimation module using the first, second and third sets of data, and the friction probability distribution is input into at least one vehicle system.
