Abstract
In a pneumatic tire, a modulus at 300% elongation of a cap tread ranges from 3.0 Mpa to 7.0 Mpa, and the modulus at 300% elongation of an undertread ranges from 10.0 Mpa to 20.0 Mpa. Additionally, an earthing tread is made from a rubber material with a volume resistivity of 1×10{circumflex over ( )}7 Ω·cm or less. The earthing tread is made from the same rubber material as the undertread and has an integral structure with the undertread.
