Introduction 14.00-25 28PR E-4 mine-type construction machinery tire design. Structural design: outer diameter of 1400mm, section width of 345mm, driving surface width 335mm, bead width of 254mm, tire toe angle of 5 °, section horizontal axis position (H1 / H2) 0.8675 using wear block deepening pattern depth 40mm. Construction design: tread with four square structure, the carcass with 12 layers of 2100dtex / 2V1 nylon 66 cord, the buffer layer using 3 layers of 930dtex / 2V3 nylon 6 cord, the traveler uses three steel ring structure. Finished tire inflatable rim size and physical performance in line with design requirements, the use of good performance.
