Abstract: Disclosed is a roller hemming device, which is capable of excellent hemming even when a subject to be hemmed is located in a relatively narrow place, and reducing maintenance frequency. Specifically disclosed is a roller hemming device, which includes a preliminary bending roller for performing preliminary bending of a work, a final bending roller for performing final bending of the work, and an arm for setting attitudes of the preliminary bending roller and the final bending roller at desired positions and angles. The preliminary bending roller has an axis inclined with respect to a horizontal direction and is arranged at such a position not to come in contact with the work during the final bending. The final bending roller is formed in a circular truncated cone, has an axis which is inclined with respect to the horizontal direction so that, during the final bending, a large diameter surface thereof faces toward the work and a processing surface thereof is horizontally positioned, and is arranged at such a position not to come in contact with the work during the preliminary bending. The preliminary bending roller and the final bending roller are arranged along a top-bottom direction, each having a processing point located in a vicinity of an axis of the arm.

Abstract: A heavy duty tire has a tread portion 2 which is divided into five inner, intermediate and outer rib-like land portions R1, R2, R2, R3 and R3. The inner rib-like land portion R1 is virtudally divided into half regions R1a and R1a on each side of a tire equator. The intermediate rib-like land portions R2 and R3 are virtually divided into tire equator-side half regions R2c and R3c, and into ground-contact edge-side half regions R2e and R3e. In a regular ground-contact state in which a normal load is applied, when total sums of ground-contact load applied to the half regions R1a, R2c, R2e, R3c and R3e are defined as P1a, P2c, P2e, P3c and P3e, P2c/P1a is set to 0.9 to 1.05, P2e/P2c is set to 0.75 to 1.0, P3c/P2e is set to 0.9 to 1.2, and P3e/P3c is set to 0.8 to 1.1.

It is possible that the tread portion is provided along the tread edges with a circumferentially extending rib and/or a circumferential row of blocks. In case of circumferential rib, the rib is provided with the curved surface comprising a plurality of the convex curves and a plurality of convex curves alternating therewith so that the curved surface is waved in the tire circumferential direction. In case of blocks in a circumferential row, it is preferable that each block is provided with the curved surface comprising at last one convex curve.
