ABSTRACT:
A tire and a tire and wheel assembly in which the wheel rim has axially-outwardly-extending portions adjacent the bead seats and the tire has in the lower sidewall region a rubber buttress having a substantially axially-outwardly-extending radially inner face. This buttress is capable of tangential flexing relative to the wheel rim so that on deflation of the tire the radially inner face of the buttress contacts the axially-outwardly-extending rim portions to support the tire sidewall and accommodate relative movement between the wheel rim and the tire sidewall.
