PROBLEM TO BE SOLVED: To markedly extend a rejection limit of a tire by effectively suppressing uneven wearing of a tread shoulder part. SOLUTION: This tire has a bead core, carcass ply comprising a radial chord layer, belt comprising one or more chord layers and a tread. In both side parts of the tread, a peripheral direction main groove 5 extended in the peripheral direction and many cross direction grooves 6, extended in the tire axial direction between the peripheral direction main groove and a tread end part to open one end part to the peripheral direction main groove and the other end part to a tread end, are provided, an uneven wearing preventing block 7, having a tire axial direction width 50% or more the length of the cross direction groove 6, is provided therein, the tire is rim-assembled in a standard rim by a regular internal pressure, when a regular load is statically loaded, the uneven wearing preventing block 7 is grounded further prevented from coming into contact with a groove side wall of the cross direction groove 6. |
