Abstract
A vehicle tire that automatically replenishes air pressure is described. The vehicle tire includes a tire portion that surrounds a wheel and is filled with air, and an air pressure replenishing member that is arranged at the inside of the tire portion and coupled with a portion of the outer surface of the wheel to replenish the air pressure when the air pressure in the tire portion is low. The vehicle tire may automatically replenish the air pressure when the air pressure in the tire portion is too low by the air pressure replenishing member, and thus fuel efficiency and driving performance of the vehicle may be maintained at a constant level.
