PURPOSE:To improve a degree of stability in time of running and circling at high speed, by making up a carcass for a tire bearing the above caption to be rectilinear in form ranging from the vicinity of the end part of a breaker arranged outside to the area contacting a bead core and also making up the breaker width to be smaller than the interval of beads. CONSTITUTION:A captioned tire 1 attached to a rim 2 is provided with a tread part 3, a side wall part 4 extending over the radial direction from both ends of the tread part and a bead part 5 situated at the inside end part in the radial direction of this side wall part 4. And, both ends of a carcass part 6 are turned up from inside to outside around a bead core 7 and this carcass part 6 is installed so as to be terminated at the bead part 5 or the side wall part 4. In this case, the carcass 6 is substantially made up in rectilinear form ranging from the vicinity of the end part of a breaker 8 to the range contacting the bead core 7. In addition, width WA of the breaker 8 is made up so as to be smaller than a bead interval WB. |
