Track for traction of a vehicle

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;
• and
• a plurality of cores at least partially embedded in the elastomeric material, distributed in a longitudinal direction of the track, and extending transversally to the longitudinal direction of the track, each of the plurality of cores comprising:
• a pair of wings extending in a longitudinal direction of the core, each wing of the pair comprising a delamination inhibitor configured to inhibit delamination of the elastomeric material from the wing;
• and
• a wheel engager disposed between the wings to engage the roller wheels.
