In article the experimental analysis of laws of influence of the pressure caused by extracontact loading, on change of the moment of a friction and rolling resistance coefficient is carried out. It is shown that cyclic pressure can (depending on test conditions) both to raise, and to reduce rolling resistance coefficient (to 60 %). It is revealed that the greatest deviation of rolling resistance coefficient in tribo-fatigue system from rolling resistance coefficient in similar pair of a friction is observed at the greatest absolute value of a parity of amplitude of cyclic pressure and the greatest value of contact pressure.
