Abstract

1444157 Pneumatic tyres INDUSTRIE PIRELLI SpA 17 Oct 1973 [23 Oct 1972] 48340/73 Addition to 1396428 Heading B7C In an improvement in or modification of the run-flat pneumatic tyre described in Specification 1,396,428, the tyre is produced by a method comprising forming and vulcanizing the tread portion 1 separately from the sidewalls 3, 4 and subsequently assembling the tread portion and the sidewalls. As illustrated in Fig. 1, the tread portion is provided with a reinforcing structure 2 and detachably engages the sidewalls at cooperating profiles 9. The sidewalls of the tyre of Fig. 2 are interconnected by a rubber layer 15 lying radially inwardly of the tread portion 1. In Fig. 5, the sidewall 3 has a projection 25 which locates in a recess of the tread portion. An element 29 located in a recess 28 assists securement of the sidewall 3 to the tread portion 1. The element 29 may take the form of a rubber or plastics ring, or a metallic helical member. In an alternative form the element 29 may be replaced by a plurality of arcuate sector members. More than one cavity 28 may be provided.
