    Abstract: A rubberized fiber material is used in a belt reinforcing layer of a pneumatic tire, and comprises polyketone fibers having substantially a repeat unit represented by the following formula (I): (wherein A is a moiety derived from an ethylenically unsaturated compound polymerized through ethylenic linkage, and may be same or different in repeat units) and a coating rubber covering the fibers, in which the coating rubber has a modulus at 100% elongation (room temperature) of not less than 2.5 MPa but not more than 5.5 MPa and a rebound resilience of not less than 60%. Also, a pneumatic tire comprises a belt reinforcing layer made from the rubberized fiber material.
