Abstract
A wheel including a tyre and a rim wherein the tyre includes: a pair of beads, each of the beads being provided with a base, wherein the rim includes a pair of axially outer flanges defining respective bead housing seats, each of the bead housing seats including a base portion, and wherein the base of at least one of the beads and the base portion of the respective bead housing seat are mutually coupled by means of at least one mechanical coupling element, wherein the mechanical coupling element is provided with parts and has a length greater than its width, the length being lower than the circumference of the tyre measured at the base of the bead and the width being lower than the axial width of the base of the bead and of the base portion of the respective bead housing seat.

A wheel for vehicles, comprising a tyre and a rim,
- wherein the tyre comprises:
- a carcass structure comprising a central crown portion and two sidewalls terminating in a pair of beads, each of said beads being provided with a base capable of being adapted to cooperate in abutting relationship with the rim;
- a belt structure, coaxially associated with the carcass structure;
- and
- a tread band coaxially extending around the belt structure,
- wherein the rim comprises a pair of axially outer flanges extending at least in part along a radial direction and defining respective bead housing seats circumferentially extending at an axially inner position with respect to said flanges, each of said bead housing seats comprising a base portion capable of being adapted to cooperate in abutting relationship with the base of the respective bead;
- wherein the base of at least one of said beads and the base portion of the respective bead housing seat are mutually coupled by means of at least one mechanical coupling element arranged at an interface between the base of the bead and said base portion of said bead housing seat;
- and
- wherein said at least one mechanical coupling element is provided with parts cooperating in abutting relationship along a circumferential and along a transversal direction and has a length measured along the circumferential direction that is greater than its width measured along an axial direction;
- said length measured along the circumferential direction being less than a circumference of the tyre measured at the base of said at least one bead and said width measured along the axial direction being less than an axial width of the base of said at least one bead and of the base portion of a respective bead housing seat.
A tyre for vehicles, comprising:
- a carcass structure comprising a central crown portion and two sidewalls terminating in a pair of beads, each of said beads being provided with a base capable of being adapted to cooperate in abutting relationship with a mounting rim;
- a belt structure coaxially associated with the carcass structure;
- and
- a tread band coaxially extending around the belt structure,
- wherein the base of at least one of said beads comprises at least one tongue seat having a length measured along a circumferential direction greater than a width thereof measured along an axial direction,
- said length measured along the circumferential direction being less than a circumference of the tyre measured at the base of said at least one bead and said width measured along the axial direction being less than an axial width of the base of said at least one bead.
A tyre for vehicles, comprising:
- a carcass structure comprising a central crown portion and two sidewalls terminating in a pair of beads, each of said beads being provided with a base capable of being adapted to cooperate in abutting relationship with a mounting rim;
- a belt structure coaxially associated with the carcass structure;
- and
- a tread band coaxially extending around the belt structure,
- wherein at least one of said beads comprises at least one substantially tongue-shaped protrusion extending from a respective base thereof, said protrusion having a length measured along a circumferential direction greater than a width thereof measured along an axial direction,
- said length measured along the circumferential direction being less than a circumference of the tyre measured at the base of said at least one bead and said width measured along the axial direction being less than an axial width of the base of said at least one bead.
A mounting rim for vehicle tyres, comprising a pair of axially outer flanges extending at least in part along a radial direction and defining respective bead housing seats, said bead housing seats circumferentially extending at an axially inner position with respect to said flanges and comprising a base portion,
- wherein at least one of said bead housing seats comprises at least one substantially tongue-shaped protrusion extending from said base portion of the bead housing seat, said protrusion having a length measured along a circumferential direction greater than a width thereof measured along an axial direction,
- said length measured along the circumferential direction being less than a circumference of the rim measured at the base portion of said at least one bead housing seat and said width measured along the axial direction being less than an axial width of the base portion of said at least one bead housing seat.
A mounting rim for vehicle tyres, comprising a pair of axially outer flanges extending at least in part along a radial direction and defining respective bead housing seats, said bead housing seats circumferentially extending at an axially inner position with respect to said flanges and comprising a base portion,
- wherein at least one of said bead housing seats comprises at least one tongue seat having a length measured along a circumferential direction greater than a width thereof measured along an axial direction,
- said length measured along the circumferential direction being less than a circumference of the rim measured at the base portion of said at least one bead housing seat and said width measured along the axial direction being less than an axial width of the base portion of said at least one bead housing seat.
