WebRim pull is the pull needed to overcome friction. Typically at lower gears of a vehicle (gears 1 and 2), the very high rim pulls can be generated. However, at low gears, one has to maintain a lower speed. At high gears of a vehicle, high speeds can be achieved but the rim pull will be less (Fig. 5.22 ).
