A sprocket wheel (50) for a track-type machine (10) may include a base portion (52) having a rotational axis (R) about which the sprocket wheel rotates, and a plurality of teeth (54) extending radially outward from the base portion. The teeth may include a tip (56), a first side wall (58) extending radially inward from the tip toward the base portion, and a first transition portion (60) extending from the first side wall. The sprocket wheel may also include a first flat (62) extending from the first transition portion toward a second flat (64) of a circumferentially adjacent tooth. The first and second flats may form an apex (69). The sprocket wheel may further include a relief surface (70) extending radially inward from the apex, with the relief surface defining a concave surface having a longitudinal axis (S) transverse with respect to a radial plane (P) perpendicular to the rotational axis of the sprocket wheel.
