Pulsar wind nebulae (PWNe) are the fastest growing class of Galactic TeV gamma-ray source as many unidentified HESS sources come to be identified with X-ray faint or "offset" PWNe. We propose to search for radio pulsations from 8 new "TeV selected" pulsars seen in Chandra and XMM-Newton images of HESS sources. Determining pulsar spin-down luminosities and ages is important for testing models in which the TeV source is powered not by the supernova shell, but by inverse Compton scattering from high-energy PWNe electrons. Both the luminosity and the spatial extent of the TeV emission should depend on these basic pulsar spin parameters, as would the possible offset of the TeV nebula from the pulsar. These trends can be established by extending the observed sample.
