Tire slippage performance testing method, tire and vehicle

The invention discloses a tire slippage performance testing method, a tire and a vehicle, and the tire slippage performance testing method comprises the following steps: preheating the tire, and then cooling the tire; setting a required slip rate loading range to obtain a slip rate theoretical curve; carrying out a longitudinal slip test on the tire on the simulated road surface in the slip rate loading range by using a test bed to obtain a slip rate test curve; decomposing the slip rate test curve into a plurality of subareas, and correspondingly adjusting control parameters of the test bench in the plurality of subareas, so that the slip rate test curve tends to a slip rate theoretical curve; performing a longitudinal slip test on the tire by using the adjusted test bed to obtain a braking force peak value and a driving force peak value; according to the method, the actually obtained slip rate can be closer to the required slip rate, and the accuracy of the result obtained by the tire longitudinal slip test
