Is it normal to hurt the tire outside the rear wheel of the car?

It's normal if you don't eat the tire or the wheel is off-center. On the surface, the wheels are in vertical contact with the ground, but in fact, when designing and installing, the wheels will form a certain angle with the ground. In order to ensure the driving stability of a car, for example, as a steering wheel, the front wheel will involve four items: caster angle, caster angle, camber angle and toe-in. As a driven wheel, the positioning of the rear wheel only involves camber and wheel bundle. From the point of view of dynamic control, the camber angle and the setting of wheelset will directly affect the wear of wheels, the portability of steering mechanism and the understeer or oversteer. There are positive camber and negative camber-from the front, the camber is negative when the upper ends of the left and right wheels are tilted inward, otherwise it is positive. Because the front wheel of the front-driven vehicle shoulders the dual mission of steering and driving, there will be understeer when turning at high speed. The understeer can be made up by setting the inclination angle of the front wheel to be positive and the inclination angle of the rear wheel to be negative. The front wheels of the rear drive only turn. When the rear wheel pushes the front wheel, it tends to oversteer, so the inclination of the front and rear wheels is just opposite to that of the front wheel.
