A tire includes annular beads, a body ply extending between the annular beads, and a circumferential belt disposed radially outward of the body ply. The tire further includes a circumferential tread disposed radially outward of the circumferential belt. At least three circumferential grooves divide the tread into two outer circumferential ribs and two inner circumferential ribs. A plurality of rib sipes are disposed on at least one circumferential rib. The tire includes a plurality of curvilinear spline sipes, wherein each curvilinear spline sipe has multiple inflection points. At least one curvilinear spline sipe is disposed on an outer circumferential rib and at least one curvilinear spline sipe is disposed on a different circumferential rib. A localized depth of the at least one curvilinear spline sipe disposed on the outer circumferential rib varies in proportion to the distance from the rib sipes that intersect the at least one curvilinear spline sipe.
