PURPOSE: A tire having a pressure sensing unit sensing an air pressure by sidewall form transformation is provided to prevent an accident by giving a micro-shape to a sidewall which is the side of a tire and checking the inner air pressure state of the tire visually and acoustically. CONSTITUTION: A tire having a pressure sensing unit sensing an air pressure by sidewall form transformation(100) comprises a pressure sensing unit(110) sensing an air pressure through the form transformation of a sidewall(102). The pressure sensing unit comprises a plate portion(112), a concave groove portion(114), and an opening and closing piece(116). The plate portion is formed on the sidewall in one body. The concave groove portion is formed to be pitted in the plate portion. The opening and closing piece is formed in the inside and outside of the concave groove portion, closes the concave groove portion when the inner air pressure of a tire is within a normal range, opens the concave groove portion when the inner air pressure of the tire becomes lower than the normal range.
