Longitudinal slip tests of the 215/55 R17 tire were carried out using a six-component tire bench test instrument. By comparing with Abaqus simulation data, the longitudinal forces and slip ratios of the tire with a constant tire pressure under different speeds and vertical loads were analyzed. A tire finite element model was established, and the energy loss of the tire under the action of ground friction was examined using the model. It was predicted that the heat loss of the tire was mainly caused partially by the sliding of the tire against the ground and partially by rolling friction. The friction force of the tire is concentrated at the shoulder position. The results showed that the longitudinal force increased with the increase in the vertical load at the same slip ratio, but the velocity had little effect on the longitudinal force. In the braking slip stage, the heat loss due to friction was greater than that in the driving slip stage. The energy loss due to friction increased with the increase in the velocity and vertical load. In the whole sliding process, the energy release due to frictional work was the largest at 80 km/h and 6396 N.
