#CMT# #/CMT# The tire has a connecting reinforcement (40) wrapping a connecting reinforcement (30) and passing radially under a coating section (22) radially at the interior of the reinforcement (30) for forming internal and external strands (41, 42). The strand (42) is in contact with radial carcass reinforcement (10) from a point (D20) till to an end point (D2) of the strands (42) on a length (V2). The reinforcement (40) is formed of a set of reinforcements oriented along an average direction making an angle equal to 50 degree with a circumferential direction. #CMT#USE : #/CMT# Tire for a heavy truck. #CMT#ADVANTAGE : #/CMT# The configuration of the tire prevents the risks of degradation of the bead of the tire by proposing the structure of the bead having a sufficient rigidity to resist the bending stresses and the circumferential movements of the reinforcements during rolling. The tire can be implemented on an industrial plan in easy and economical manner. The ends of the radial carcass reinforcement are placed between two connecting reinforcements, thus ensuring the better effectiveness of mechanical resistance of the reinforcement in each bead and avoiding the contact of the reinforcement with the bead wire, in case of the usage of the tire. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a transversal sectional view of a tire.
