text: According to one aspect of the present invention, a pneumatic radial tyre comprises a carcass extending from a tread part through sidewall parts and folded at each edge around a bead core of a bead part, and a belt layer composed of belt plies disposed radially outside said carcass, where in a tread surface is formed along a specific plane of curvature including a first arc with a radius of curvature R1 having a centre on the tyre's equatorial plane and passing though the tyre's equatorial point, a second arc with a radius of curvature R2 having a centre on the tyre's equatorial plane and intersecting said first arc at an intersection spaced from the tyre's equatorial plane by a distance 0.2 to 0.25 times the tyre width SW, and a third arc with a radius of curvature R3 passing through a ground contact outer edge point of the ground contact surface in the axial direction of the tyre when considered with a standard load applied and a belt intermediate height point on the tread surface when the belt intermediate height point on the tread surface is defined as the point which a tyre axial direction line extending parallel to the tyre's axis from a thickness centre of the belt layer at an axially outer edge of a region where at least two belt plies overlap to each other crosses the tread surface and the tread surface is provided with a main circumferential groove extending near said intersection of the first arc and the second arc in the tyre circumferential direction dividing the tread surface into the crown part and its outer shoulder parts.
