A tire having a carcass reinforcement, a crown reinforcement and a tread joined to two beads by means of two sidewalls, the axially outer edges of the single mix of the tread being folded over on to the radially outer edges of the rubber mixes of the sidewalls, and the circular junction J between the sole rubber mix of the tread and the rubber mix of the sidewall being positioned such that its radius R on the axially outer wall of the tire lies firstly between 0.9 R &plus;0.1 R and 0.8 R &plus;0.2 R and secondly between R and 0.9 R &plus;0.1 R , R being the equatorial crown radius of the tread, R the equatorial radius of the center line of the carcass reinforcement and R the radius of the bead seat.

Junction of a tread with the sidewalls of a tire

A tire having a radial carcass reinforcement covered radially on the outside by a crown reinforcement consisting of two working plies of reinforcement elements crossed over and making angles of between 10&deg; and 45&deg; with respect to the circumferential direction, the carcass reinforcement in its portion underneath the crown reinforcement being formed of cut reinforcement elements.
