A tire is provided that has a tread with has a first material and a second material. The first material has a G* complex shear modulus at 60° C. that is greater than a G* complex shear modulus at 60° C. of the second material so that the first material is more rigid than the second material. The G* complex shear modulus at 60° C. of the second material is from 50%-88% of the G* complex shear modulus at 60° C. of the first material. The tread has a plurality of teardrop sipes that have a teardrop void that has a cross-sectional width. One of the teardrop sipes is located in the first material with the teardrop void cross-sectional width sized such that no more than five percent of the other teardrop sipes located in the second material have a larger than or equal teardrop void cross-sectional width.
