A bridge having a bottom surface which is bulged is formed at a portion of the lug groove near the first circumferential groove. The bridge has a cross-sectional shape of a trapezoid with tapered surfaces in which side surfaces of the lug groove at an end near a center in a longitudinal direction and an end near the first circumferential groove are inclined with heights thereof reduced toward corresponding ends of the bridge.
