Abstract
A tire comprises two working crown layers of reinforcing elements and, in each shoulder, an end of a layer of parallel reinforcing elements oriented circumferentially, said end being axially outside the working crown layers. The reinforcing elements have a diameter less than 1 mm and comprise threads with a diameter strictly greater than 0.16 mm, and, in a radial plane, the ratio between the thicknesses of rubber compound between the inner surface of the tire cavity and that point of a metal reinforcing element of the carcass reinforcement that is closest to said inner surface of the cavity, of the two parts of the tire profile that are centered on the respective orthogonal projections onto the inner surface of the tire cavity of the axially outer ends of said additional layers, and of the parts of the tire profile that have the smallest thicknesses, being greater than 1.15.
