Abstract: Off road tires having a blended layer arranged in the crown portion are described for improving adhesion between the tread and underlying or adjacent tire components. Increased adhesion between tire components can reduce the frequency of separation and increase the service life of the tire. The blended layer contains a portion of the same material composition of a tire component that contacts the layer to ensure the blended layer has ingredients common with the adjacent component. As arranged between two tire components or layers, the blended layer can have a first portion and a second portion corresponding to compositions of the layers in contact with the blended layer. The incorporation of compositions in contact with the blended layer allows the blended layer to simulate entanglement between materials and increases the bonding strength between the layer and other components in the tire.

Abstract: Various embodiments of a tire wear indicator are provided. In one embodiment, a tire having a tread is provided, comprising: a ground-contacting portion oriented at the radially outermost surface of the tire; at least one notch extending radially inward from the ground-contacting portion, wherein the at least one notch includes at least one notch sidewall and a notch base; at least one tire wear indicator extending from the at least one notch sidewall partially into the at least one notch; wherein the at least one tire wear indicator does not extend completely across the at least one notch; and wherein the at least one tire wear indicator does not directly contact the notch base.
