The compromise between the performance aspects of endurance and wear of a tyre for construction plant vehicles is improved, while limiting the mean operating temperature thereof to an appropriate level of around 100° C., and while ensuring its capacity of being electrically conductive, that is to say of discharging electrostatic charges that have built up during running. For this purpose, the tread comprises three parts: two electrically conductive tread wings and a central portion that is optimized in terms of hysteresis and is therefore not electrically conductive. The pathway for discharging electrostatic charges connects the tread wings to the rim, passing via electrically conductive edging rubbers positioned at the axial ends of the layers of the crown.
