Abstract
Provided are a pneumatic tire with improved air dispersibility in a reinforcing layer including steel cords during vulcanization and with effectively suppressed blistering, and a method of manufacturing the same. In the pneumatic tire according to the present technology including a reinforcing layer (10) including a plurality of aligned steel cords (11) coated with coating rubber (12), at least one thread (13) for extending in a longitudinal direction of the steel cords (11) is disposed between the steel cords (11) in the coating rubber (12).
Claims11
A pneumatic tire comprising:
- a reinforcing layer including a plurality of aligned steel cords coated with coating rubber, wherein
- at least one thread for extending in a longitudinal direction of the steel cords is disposed between the plurality of aligned steel cords in the coating rubber.
A method of manufacturing a pneumatic tire, the method comprising:
- inserting at least one thread between a plurality of aligned steel cords to extend in a longitudinal direction of the plurality of aligned steel cords, in rolling the plurality of aligned steel cords along with coating rubber between a pair of rollers, to form a reinforcing layer including the plurality of aligned steel cords and the at least one thread;
- then forming a green tire comprising the reinforcing layer;
- and
- vulcanizing the green tire.
A method of manufacturing a pneumatic tire, the method comprising:
- inserting at least one thread between a plurality of aligned steel cords to extend in a longitudinal direction of the plurality of aligned steel cords, in passing the plurality of aligned steel cords along with coating rubber through a die, to form a reinforcing layer including the plurality of aligned steel cords and the at least one thread;
- then forming a green tire comprising the reinforcing layer;
- and
- vulcanizing the green tire.
