FIELD: agriculture.

SUBSTANCE: tread (2) contains the main elements (21) of the tread pattern with a radial height HR1 and the secondary elements (31) of the tread pattern, located longitudinally between the main elements (21) of the tread pattern, with a radial height HR2, having a front surface (312), which is inclined forward to the corner α with respect to the radial direction (Z) in accordance with the direction (15) of the tread movement, and the contact surface (311) tilted back at an angle β relative to the radial direction (Z) in accordance with the direction (15) of the tread movement. According to the invention, the ratio of HR1 to HR2 is at least 4, the angle α ranges from 5 to 15 degrees, the angle β is from 95 to 110 degrees, and the longitudinal pitch L, which separates the secondary tread elements from each other, is from 5 to 50 mm.

EFFECT: improved traction characteristics on loose soil.
