The construction design of 17.5-25 14PR TT L-3 OTR tire is presented in this paper. The tire building drum is half-core type and had a wheel structure with a die having diameter of 800 mm and width of 892 mm. 8 layers of 1840dtex/2 Nylon 6 cord are used in the carcass ply, and 4 layers of 930dtex/2 Nylon 66 cord and 1 layer of breaker rubber are applied in the breaker ply. All the cord fabrics are cut at the angle of(30± 0.5)°. Four formulations and ifve piece structure are adopted for tire tread and the breaker rubber layer is hotly coated under the tread. The tire bead has 3-3-2 type structure and the bead wires are arranged in order of 9×9×2. During the tire production, the cord fabrics for carcass ply and breaker ply are cut by using horizontal and vertical cutting machine, respectively. The tread is co-extruded. The tire is built on the PU type building machine by using sleeve method and then cured on automatic curing machine. The process yield is high, and the test results of tire performance in both experimental test and actual service are good.
