摘要： In a tire for a heavy load in which a belt is formed by laminating rubber-coated cord layers prepared by embedding steel cords in a coating rubber, an end part of at least one rubber-coated cord layer or an end part of the belt is coated with a rubber composition containing trans-polybutadiene (TRBR) and bismaleimide (BMI) in the following compounding amounts based on 100 parts by mass of a rubber component containing natural rubber and isoprene rubber: 0.1 part by mass≦TRBR+BMI≦0.0 parts by mass TRBR/(TRBR+BMI)≧25% whereby cracks originating from separation between the steel cords at an end part of the belt and the coating rubber are prevented from being generated.

摘要： The present invention is a method for producing a tire casing by vulcanizing a casing portion comprising a belt portion composed of multiple belt layers, a side portion and a bead portion, and the method includes at least one method selected from the following (a) and (b). The invention also provides a production method for a tire casing and a tire having improved low-heat-generation property and durability. Method (a) in which a rubber composition containing carbon black having a nitrogen adsorption specific surface area of from 38 to 99 m2/g as defined in JIS K 6217-2:2001, in an amount of from 40 to 60 parts by mass relative to 100 parts by mass of the rubber component therein is used as the belt wedge rubber of the belt portion. Method (b) in which the tire casing comprises a carcass ply and an inner liner composed of multiple layers, and a rubber composition containing carbon black having a nitrogen adsorption specific surface area of from 25 to 60 m2/g as defined in JIS K 6217-2:2001, in an amount of from 45 to 60 parts by mass relative to 100 parts by mass of the rubber component therein is used as the layer of the inner liner adjacent to the carcass ply.
