发明名称 PNEUMATIC TIRE
摘要 Provided is a pneumatic tire having an excellent finished bonding surface between the tread and its adjacent wing or sidewall while ensuring properties required for tires, such as wet grip performance, abrasion resistance, and resistance to degradation over time. Included is a pneumatic tire including a tread and a wing or sidewall adjacent to the tread, wherein the tread is formed from a tread rubber composition that has an amount of aluminum hydroxide having an average particle size of 0.69 µm or smaller and a N 2 SA of 10-50 m 2 /g of 1-60 parts by mass, and a net sulfur content derived from crosslinking agents of 0.56-1.25 parts by mass, each per 100 parts by mass of the rubber component, the wing or sidewall is formed from a wing or sidewall rubber composition that has a net sulfur content derived from crosslinking agents of 1.3-2.5 parts by mass per 100 parts by mass of the rubber component, and the net sulfur contents derived from crosslinking agents in the tread rubber composition and the wing or sidewall rubber composition satisfy a specific relationship.
