We present a theoretical analysis of the recent experimental results of Thomas et al on transport properties of spin polarized quantum wires. We suggest an explanation of the observed deviations of the conductance from the universal value G=2e2/h per channel in the wire. We argue that the new quasi plateau observed for the conductance at the value G=1.4e2/h is a result of the proximity between the spin polarized phase and the metallic one. The enhancement of the conductance from the value G=e2/h to G=1.4e2/h is due to the hybridization of the electronic state at KF\downarrow≈ 0 with the chiral states at KF\uparrow and -KF\uparrow.
