A tire includes a circumferential tread having a base layer and a cap layer disposed above the base layer. The base layer is constructed of a first material having a first complex dynamic modulus and a first glass transition temperature, and the cap layer is constructed of a second material having a second complex dynamic modulus greater than the first complex dynamic modulus and a second glass transition temperature higher than the first glass transition temperature. The base layer has a shaped geometry with a bottom portion that is wider than a top portion, such that an exposed surface area of the first material increases as the circumferential tread wears.
