1. A track for traction of a vehicle, the track being mountable around a plurality of wheels that includes a plurality of roller wheels for rolling on a bottom run of the track along a rolling path of the track, the track comprising:
a ground-engaging outer side;
an inner side opposite to the ground-engaging outer side;
elastomeric material allowing the track to flex around the wheels;
a plurality of cores at least partially embedded in the elastomeric material, distributed in a longitudinal direction of the track, extending transversally to the longitudinal direction of the track, and each comprising a guide projection on the inner side of the track for contacting the roller wheels to guide the track; and
a cracking inhibitor disposed along the rolling path, overlapping with one of the guide projections in the longitudinal direction and in a widthwise direction of the track, and configured to inhibit cracking of the elastomeric material at the rolling path, wherein
the cracking inhibitor has a bottom surface with a height that varies, and
the height of the bottom surface is greater at a first portion of the cracking inhibitor between the guide projection and an outer lateral edge of the rolling path in a widthwise direction of the track than a second portion of the track aligned with the guide projection in the widthwise direction of the track.
