Abstract
A tire safety support for mounting on a wheel rim to support a pneumatic tire in a deflated condition including a ring member mounted on the wheel rim inside the tire. The ring member has a tread support portion spaced radially outward from the rim which is radially deflectable when a radial load is applied to a deflated tire. A deflection limiting member is mounted on a rim-engaging portion of the ring and extends radially outward to a supporting surface spaced a predetermined distance from the tread support portion of the ring member to limit deflection of the tread support portion upon deflation of the tire.
Claims8
A tire safety support for use on a wheel rim to support a pneumatic tire mounted thereon in a deflated condition comprising a ring member mountable on a wheel rim inside the tire, said ring member including a rim-engaging portion, an axially extending tire tread support portion spaced radially outward from said rim-engaging portion for supporting a portion of the tire tread from the inside thereof when deflated, an intermediate portion joining said rim-engaging portion and said tread support portion, said tread support portion being radially deflectable when a radial load is applied thereto by a deflated tire, said ring member having at least one radial split extending therethrough to permit the ring to pass through the bead of the tire, a radially extending deflection limiting member mounted on said rim engaging portion and extending radially towards said tread support portion, said deflection limiting member having a radially outer supporting surface spaced a predetermined distance from said tread support portion to limit the deflection of said tread support portion.
A deflection limiting member for use on a radially deflectable tire safety support mounted on a wheel rim to support the tire in a deflated condition comprising an angle bracket having a curved base leg for mounting on a circumferentially extending surface of said support, a support leg extending from said base leg at an angle of substantially 90.degree. to a plane tangent to the arc of the curve of said base leg and a shoe mounted on the end of said support leg for engagement by said tire safety support to limit the deflection of said tire safety support caused by forces acting on the tire during deflation.
