This is a form of molecular friction, and it is related to the surface area on the road. When a race car slides, it is more controlled with this type of tire than with a tire with treads, which may skid suddenly. In conclusion When a wheel is pushed above its axis, the static friction at the bottom causes it to start rolling. Applying a torque at the axis is like applying a force at the edge of the wheel. Too much torque can cause the wheel to spin.
Tires deform, adding to their friction.
They also have treads, which can provide extra friction. It would slide instead of rolling 2. No force is necessary for a tire to roll down hill 3. If you got all three correct, you are on your way to becoming a champion in science. If you had problems, you had better look over the material again.
