  • Tire sidewall for a heavy duty civil engineering vehicle
    Patent number: 11331948
    Abstract: A radial tire (10) for a heavy vehicle of construction plant type, and more particularly, the sidewalls thereof (20), arranged to minimize the temperature of the tire while guaranteeing its electrical conductivity. The tread (30) comprises two tread wings (31) and a central portion (32). The bead layer (71), the elastomeric coating compound of the carcass layer (50), the second sidewall layer (22) and the tread wing (31) constitute a preferential conductive pathway of the electric charges between the rim and the ground when the tire is mounted on its rim and flattened on the ground.
    Type: Grant

  • TIRE SIDEWALL FOR A HEAVY DUTY CIVIL ENGINEERING VEHICLE
    Publication number: 20190351716
    Abstract: A radial tire (10) for a heavy vehicle of construction plant type, and more particularly, to the sidewalls thereof (20), aims to reduce the surface cracking of the tire sidewalls and slow down the propagation of cracks in the thickness of the sidewall. The tire (10) comprises two sidewalls (20), each sidewall (20) consisting of a laminate comprising at least first and second sidewall layers (21, 22) that are axially superposed and have a total thickness E, the axially outermost first sidewall layer (21) having a thickness E1 and consisting of a elastomeric compound M1, the axially innermost second sidewall layer (22) having a thickness E2 and consisting of a second elastomeric compound M2. The thickness E1 is at most equal to 0.9 times the total thickness E, the thickness E2 is at least equal to the minimum value between 3 mm and 0.
