No. The purpose of run-flat tires are to get you to pull off the road safely, or travel a small number of miles at low speeds to somewhere where you could have a replacement mounted and installed immediately. They are not intended to run without air for extended periods of time, or at highway speeds. They are also not to be driven on AT ALL in the event of a sidewall puncture.

The casing would still fail catastrophically at high speeds (i.e. pursuit scenario), and having a tire down over 30psi on one wheel would very seriously affect handling at any significant speed (40mph or more).
