Pneumatic tire

A pneumatic tire comprising:

• a carcass;
• a belt layer arranged on an outer circumference of a crown of the carcass;
• and
• a belt reinforcing layer arranged on an outer circumference of the belt layer, wherein
• the belt layer has belt ply in which steel cords are arranged at an angle to a tire circumferential direction,
• the belt reinforcing layer has a belt reinforcing ply on the outer circumference of the belt layer, the belt reinforcing ply having organic fiber cords arranged in the tire circumferential direction,
• a filament diameter of each steel cord is more than 0.10 mm and less than 0.25 mm,
• each organic fiber cord is a composite fiber cord formed by twisting yarn made of aliphatic polyamide fibers with yarn made of aromatic polyamide fibers,
• a fineness of the aliphatic polyamide fibers is 900 dtex or more, and
• A, B, and C satisfy relationships represented by the following Expression (I) and Expression (II),
