Abstract
A pneumatic radial ply runflat tire for a vehicle has a tread , a carcass comprising at least one radial ply and two sidewalls each reinforced by a circumferentially disposed crescent-shaped wedge insert. Each insert has an elastomeric porous section embedded in an elastomeric stiffer layer of the insert When the tire is normally inflated, the porous section and hence the insert as a whole, is flexible, thereby providing comfortable driving characteristics. Under runflat (deflated tire) conditions, the pores in the porous section collapse, and the porous section stiffens, and hence the insert as a whole becomes stiff enough to support the load of the vehicle.
