<P>PROBLEM TO BE SOLVED: To provide a precure tread capable of imparting the weatherability to a wing section, and obtaining sufficient adhesiveness between the precure tread and a tire casing, and a pneumatic tire to be manufactured by using the same. <P>SOLUTION: In the precure tread having wing sections 3 on both ends of a tread section 2, the rubber component constituting the wing sections 3 is formed by (A) ≥15 mass% ethylene-propylene-diene rubber is singly blended, or (B) ≥20 mass% the total of ethylene-propylene-diene rubber and halogenated butyl rubber is blended. In the pneumatic tire, the precure tread is subjected to the covulcanized adhesion to an outer periphery of a crown section of a precure tire casing 4 having no pre-vulcanized tread section via a non-vulcanized cushion rubber layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
