Abstract
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.
