The tire (10) comprises a crown (12) surmounted by a tread (22), two sidewalls (24), two beads (26), each sidewall (24) connecting each bead (26) to the crown (12), a carcass reinforcement (34) anchored in each of the beads (26) and extending in the sidewalls (24) as far as the crown (12). The carcass reinforcement (34) comprises one carcass ply (44) comprising carcass reinforcing elements (46) having a mean laying pitch (P) strictly greater than 1.5 mm. The carcass ply (44) comprises an elastomer matrix (54) in which the carcass reinforcing elements (46) are embedded, each carcass reinforcing element (46) comprising: one filamentary element (56), and one sheath (58) coating the filamentary element (56) and comprising at least one layer (60) of a thermoplastic polymer composition.

A tire can include beads, a carcass, sidewall layers, a tread, a belt, and a band. A carcass ply of the carcass can include a ply body and a pair of turned-up portions. An end of each turned-up portion can be located axially inward of an end of the belt. A ratio of a thickness from the carcass to an outer surface of the tire along a first normal line to a thickness from the carcass to the outer surface of the tire along a second normal line can be not less than 1 and not greater than 2.
