PROBLEM TO BE SOLVED: To prevent development of an ozone crack on a recessed bottom as well as to prevent generation of separation toward carcass winding end even with increase in circumferential shear strain due to increased flatness of the tire. SOLUTION: A tire with aspect ratio of 70% or less in a state where it is assemble to a standard rim RI and filled with a maximum pneumatic pressure, the tire has, in a radial direction thereof, a recessed line 8 of a tire outer surface recessed toward inside in the width direction between a winding end 2b of a carcass end 2a and a maximum width position 13 of a carcass 2. Further, a thickness G of a covered rubber layer on an imaginary extension of the carcass end 2a in a range between a position of the winding end 2b in the tire radial direction and a radial distance B corresponding to a thickness G0 of a covered rubber layer 7 at the winding end 2b is 0.7 to 1.3 times the thickness G0 of the covered rubber layer 7.
