Hi,
I'm doing a study about tire dynamics and have some question that I can't get answers to.
The first images shows the forces balances. Since we have no turqe the force has to balance ant the extensence of the T_r is obvious.

However in the below picture when a Turqe is present we have a Driving resistence which I don't understand. You have the rolling resistance ofcourse but what is the driving resistance. The do not talk about aerodynamic force so it should not be it. and we see that T_d is to opposite direction of the movement. why is that? and how does it feel? it pushes the tire backwords? the presence of Driving force would explain it but what is it?

On the brake phase you have the driving resistance backwords too and it make the T_b forwards. Please somebody explain it to me.

Thanks in advance
