Does speed matter?

I am agree with all terms but be aware that grip and sliding are different. When the wheel grip, the grip-force power the vehicule and help him to climb. When the wheel slid, the grip force power the vehicule but this grip force is lower than in first case. Also, grip force depends of tyres and linear speed of point of contact. Therefore, your experiment is right but only on smooth surface.
