Abstract:
A runflat radial ply pneumatic tire (10) having a carcass (30) reinforced with at least two sidewall fillers or inserts (42, 46) and at least one cord reinforced ply (38) and two bead cores (26) and one or more reinforcing belts (36). The at least one ply (38) reinforced with cords, the cords have a pair of turnup ends (32) wrapped around the pair of bead cores (26). The turnup ends (32) extend radially outwardly to a terminal end (33), the terminal end (33) being located under the reinforcing belts (36). The first insert (42) lies radially inward and adjacent the ply (38). The second insert (46) lies radially between the ply (38) and its turnup end (32). The tire (10) requires a reduced number of components and can be lighter in weight than the prior art runflat tires.
