Tread () of a radial tire for a heavy vehicle. The tire alternatingly rolls in laden and unladen states on descent and ascent, respectively. Tread () has total width Wand comprises first median portion () having median width W, where 0.2W&#x2264;W&#x2264;0.5W. Tread () is axially delimited by second and third lateral portions () having respective lateral widths (W, W) at least equal to 25% and at most equal to 40% of total width W. Angle Aof leading face () of every element in relief () of first median portion () is strictly greater than angle Aof trailing face () of said element in relief (). Angle (A, A) of leading face () of every element in relief () of each of the second and third lateral portions () is strictly less than angle (A, A) of trailing face () of said element in relief ().

Materials make it possible to generate mechanical coupling in elastomeric compositions, of use especially for the manufacture of tyre treads. In particular, a tread comprises a composite material based on an elastomeric matrix, a crosslinking system, a reinforcing filler and oriented short fibres.

Heavy-duty vehicle tire

Tire tread

A vehicle () comprising at least two axles () fitted with at least two tires the axis of rotation of which are always mutually parallel from one axle to another. Each axle () bears at least 10% of the load of the vehicle and at least two axles () bear different loads during running. Also disclosed is a method for distributing the load between said at least two axles.
