A TYRE FOR VEHICLE WHEELS WITH SELF-SUPPORT FUNCTIONS, AND A RIM FOR SAID TYRE

摘要

A tyre for vehicle wheels has a pair of beads (5) each having a frusto-conical rest surface (5a) and showing a cross-section profile converging towards the rotation axis of the tyre (1) away from an equatorial plane (X-X) of same. Each bead (5) incorporates an annular anchoring structure (4) comprising an anchoring portion (16) of a flattened profile extending in parallel to the rest surface (5a), and a stiffening portion (12) extending in a radial direction. Associated with the carcass structure (2) is a circumferential centring ridge (20) radially jutting out within the tyre (1) at a crown portion of the latter. Also described is a rim (23) provided with engagement seats (24) the shape of which matches that of the beads (5) and with a guide race (25) conforming in shape to the centring ridge (20).
