The safety support (10), mounted on a vehicle wheel between the rim and tyre (7), has an outer surface (30) in three sections (31, 32, 33). Its central section (31) has a maximum radius (Rmax) from the wheel's axis (X - X'), while its two outer sections (32, 33) have a minimum radius (Rmin, R'min) and are connected to the central section by transitional zones (311, 312). - The safety support (10), mounted on a vehicle wheel between the rim and tyre (7), has an outer surface (30) in three sections (31, 32, 33). Its central section (31) has a maximum radius (Rmax) from the wheel's axis (X - X'), while its two outer sections (32, 33) have a minimum radius (Rmin, R'min) and are connected to the central section by transitional zones (311, 312). The dimensions of the maximum and minimum radii are determined by the camber of the tyre surface when running deflated. In addition, the support has a series of radial partitions distributed round its circumference and extending axially across its median circumferential plane. |
