Abstract
A vehicle is provided with wheels fitted with pneumatic tires, and a vehicle body including wheel wells that surround the wheels. The pneumatic tire includes a plurality of protrusions on a sidewall portion that faces a predetermined wheel well side surface. An average normal vector of the wheel well side surface is inclined with respect to a rotation axis of the wheel. In such a configuration, when the vehicle is traveling and the tires are rotating, an air flow promotion effect and rectification effect are produced due to the protrusions on the sidewall portion, and negative pressure forms between the tire and the wheel well side surface.
