To analyze the impact of slope obstacles on tire, the collision forces between tire and underwater bulge obstacle were obtained using vibration equation in the vertical direction of single-degree-freedom system. With the support of ANSYS software, the simulation model was established to study the stress and deformation of tire model under collision with an underwater obstacle on a 20.3-degree slope of 50 mm elevation, and on a slope of the same degree and elevation but without obstacles. The results showed that the maximum stress of the tire increased sharply when the tire entered the slope. After the tire continued to climb, the stress increased slowly as displacement increased. When the tire reached the middle position, the stress reached its maximum at 24.73 MPa, which mainly appeared at the inner ring of the tire. Therefore, it is important to eliminate tire instability immediately after the tire enters the slope and before it meets the maximum stress.
