Pneumatic tire and method of manufacturing pneumatic tire
A pneumatic tire is provided with a carcass layer and a sidewall rubber disposed on an outer side in a tire width direction of the carcass layer. Additionally, the pneumatic tire is provided with a resin coating applied on a predetermined region of a sidewall portion. Additionally, a minimum value of a wall thickness t of a rubber of the sidewall portion in the region applied with the resin coating is in a range of 0.05 mm≤t≤4.0 mm. Additionally, a thickness of the resin coating is in a range of 20 μm or more and 300 μm or less.
1. A method of manufacturing the pneumatic tire comprising a carcass layer and a sidewall rubber disposed on an outer side in a tire width direction of the carcass layer, the pneumatic tire comprising a resin coating applied on a predetermined region A of a sidewall portion, a minimum value of a wall thickness t of the sidewall rubber in the region A applied with the resin coating being in a range of 0.05 mm≤t≤4.0 mm, the method comprising the steps of:
filling a green tire in a tire vulcanizing mold for vulcanization molding; and applying the resin coating on a tire in the tire vulcanizing mold by injecting a coating material in the tire vulcanizing mold.
