A tire for an agricultural vehicle (1), and in particular the carcass reinforcement (4) thereof, for a tire running at low pressure on loose ground, is to reduce the compaction of the ground and to increase the traction capability by reducing the structural stiffness of the tire. According to the invention, the carcass reinforcement (4) is made up of a single carcass layer (41) having a mean thickness E at most equal to 2 mm and a breaking strength Fr, expressed in daN/cm, that satisfies the relationship:Fr>=Fs=(Cs*Pmax*10−3)*((R2−((R+Rj)/2)2)/2)/Rj, withFs: reference threshold strength (in daN/cm)Cs: safety factor at least equal to 1,Pmax: recommended maximum inflation pressure (in kPa),R=D/2: outside radius of the tire (in mm),Rj=Dj/2: nominal radius of the rim (in mm).
