We investigate the influence of electron-phonon interactions on the
DC-conductance $\Gamma $ of a quantum wire in the limit of one occupied
subband. At zero temperature, a Tomonaga-Luttinger-like renormalization of
$\Gamma $ to a value slightly larger than $2e^{2}/h$ is calculated for a
realistic quantum wire model.
