An endless track for traction of a vehicle, such as a construction vehicle, an agricultural vehicle, a forestry vehicle or a military vehicle. The endless track has an enhanced elastomeric material curing capability. In one embodiment, each of a plurality of elastomeric projections of the endless track, such as guide/drive projections or traction projections, comprises elastomeric material defining a cavity to enhance a curing process during manufacturing of the endless track. The cavity may be shaped such that, during the curing process, a heat conductor positioned in the cavity conducts heat from the heat conductor to the elastomeric material of the projection.
