It is called friction
Out of balance. More weight on one part of the tire than another.
Kinetic friction is the type of friction that causes a tractor wheel to slip in mud. When the wheel is already in motion, the mud creates resistance against the wheel's movement, resulting in slipping.
About the only thing that will cause the wheel to bounce on any car is the strut being bad.
bad bushings on the rack mount making it loose hence turning stering wheel will make it loose and bounce == Have the rack/box pipes been tampered with? Is it manual or power steering? Does this happen whilst driving or if the vehicle is stationery? www.powerbrakeandsteering.co.za
Worn struts/shocks, tire out of balance, or bent wheel.
Friction between the brake pads and the wheel rim or disc creates the force that causes a bicycle to stop when its brakes are applied. This friction generates heat as the brake pads press against the wheel, gradually slowing down and eventually halting the rotation of the wheel.
the answer is you just don't do that. and if you did. you must of hit a horse. because otherwise. the wheel wouldn't bounce. only everyone in the world knows that.
Tire out of balance or bent wheel.
The forces acting on a static wheel are typically the normal force from the ground pushing up on the wheel, gravity pulling the wheel downward, and the force of static friction keeping the wheel from moving.

Take a look at the picture by using the link to the Wikipedia article, then come back and read the answer. The wheel has a steel axle, and it also has magnets built into it. The magnets keep the wheel in contact with the track on which it rolls. The operator need only time the movement of the track to keep the wheel rolling.
