20250282184 · 2025-09-11 ·

A tire of the high load capacity type for a passenger vehicle, comprises a smooth reference surface (44), and at least one molded recessed element (46) and/or at least one molded projecting element, recessed or projecting being with respect to the smooth reference surface (44). A maximum thickness Emax, the maximum depth Pmax of each molded recessed element (46) and/or the maximum height Hmax of each molded projecting element satisfy Emax{circumflex over ()}(0.4)Pmax1.1 and Emax{circumflex over ()}(0.4)Hmax1.1, Pmax and Hmax being expressed in mm. Emax is the maximum distance between the axially outermost reinforced layer (36) and the smooth reference surface (44). Emax is less than or equal to 3.0 mm.

Pneumatic tire

In a pneumatic tire, a turned back portion of a carcass layer contacts a body portion of the carcass layer in a cross-sectional view in a tire meridian direction to form a closed region surrounding bead cores. A rubber occupancy ratio in the closed region is in a range of 15% or less. The bead cores have a predetermined wire arrangement structure formed by arranging wire cross sections of bead wires in the cross-sectional view in the tire meridian direction. Additionally, a self-contact height (CH) of the carcass layer and a circumferential length (L) of the wire arrangement have a relationship 1.0CH/L10.0.

PNEUMATIC TIRE EQUIPPED WITH A TRANSPONDER

Pneumatic tire having a toroidal carcass, which includes a body ply that is partially folded onto itself and therefore having two lateral flaps; two annular beads, each of which is surrounded by the body ply and has a bead core and a bead filler; an annular tread; a pair of sidewalls; a pair of abrasion gum strips; an innerliner which is impermeable to air and arranged within the body ply; and a transponder which is arranged between the body ply and the innerliner at a flap of the body ply. Between a radially outer end of the transponder and an edge of the body ply a first radial distance is provided that is greater than 7 mm; and between a radially inner end of the transponder and an edge of the bead filler a second radial distance is provided that is greater than 7 mm.
