The tread pattern of a tire for a vehicle for agricultural use comprises two rows of lugs (R, R), a first row being made up of a circumferential distribution of at least two families of lugs, over one revolution of the wheel; a first family is reproduced with a shortest spacing S, and a second family is reproduced with a longest spacing L; the tread pattern of the tread is designed such that the distance between the axially outer end of a following lug and the axially inner end at the centre of the tread is referred to as the overlap distance R. The ratio of the shortest spacing S of the family of lugs to the longest spacing L, 'S/L', lies in the range [0.6; 0.8]. The circumferential overlap distance R between the first and second circumferential rows of lugs is constant around the entire circumference of the tire.

Tire for an agricultural vehicle

A tread and tire for a multipurpose agricultural machine, that improves field traction while ensuring a satisfactory compromise with wear under engine torque and vibratory comfort on the road having a tread having a plurality of lugs distributed in a first row extending axially from a first axial end of the tread and in a second row extending axially from a second axial end of the tread, the second row differing from the first row by a symmetry relative to the equatorial plane of the tire followed by a rotation about the rotation axis of the tire, each row having an alternation of long lugs and of short lugs. The axially inner end face of a first long lug of a row of lugs is separated from the trailing lateral face of the second long lug of the symmetrical row of lugs, closest to the axially inner end face of the first long lug, by an end groove with a width at least equal to 10% and at most equal to 100% of the lug height.

Tread for the tire of a farm tractor

Tire pressure regulation method and system for an agricultural vehicle equipped with tires. In order to improve the pressure management of the tires connected to the tire pressure regulation system, a pressure setpoint is determined by determining the characteristics of the tires, the pressure of which is intended to be regulated by the tire pressure regulation device, determining the speed of the vehicle, calculating the pressure setpoint of the tire depending on the characteristics of the tire and on the speed.

Tire pressure regulation system for a vehicle and method for such a system

A method for fitting tires (P) to a driving axle of a vehicle carrying heavy loads, which consists, after having determined the type of journey made by said vehicle, in: A tire (P) appropriate for implementing the method described.
