    摘要: An emergency ring of elastic material for a vehicle wheel having a one-piece deep bed rim comprises a one-piece annular support body, which via support rings are supported exclusively on the rim bed of the wheel and is spaced apart from at least one side wall region or of a pneumatic tire. Reinforcement inlays are disposed radially such that there is only relatively little compressible elastic material within the reinforcement inlays. High security against rotation of the emergency ring relative to the rim is thereby assured. Moreover, the emergency ring is easily mounted and provides great security against a tire being thrown off, even when cornering with tires with low air pressure.
