Abstract
Tire () for an off-road vehicle, comprising a crown and a tread () having a width W and a thickness E of wearable material, this tread () having a superposition of at least two layers of materials, a first layer () radially on the inside and a second layer () radially on the outside of the first layer () to contact the ground when the tire is new, this second layer () having a thickness E2 relative to the thickness E of wearable material, the tread () being provided with at least two narrow grooves () running all around the tire which have a zigzagging shape of wavelength L and amplitude A, the wavelength L being between 10% and 120% of the axial width W of the tread (), and the amplitude A being between 10% and 75% of axial width W. The material of the first layer () is chosen with low hysteresis; with a measured tan(δ) value at most equal to 0.30.
