The influence of belt angle on the footprint,lateral stiffness and aligning stiffness of 205/55R16 electric vehicle tires was studied by finite element technique.The results showed that as the belt angle increased,the tire footprint gradually changed from square to slightly circular,the length of the short axis of the footprint decreased,the length of the long axis of the footprint increased,and the area of the footprint increased.Under the same load with different inflation pressures and the same inflation pressure with different loads,as the belt angle increased,the tire's lateral stiffness decreased and the aligning stiffness increased.
