    There have been reports of people driving on run flats with no pressure for way more than 50 miles. Like, 150 miles or more, without problems. I wouldn't try to repair and reuse that tire, but the 50 mile recommendation is as much to cover the manufacturers butt as a real limit. So if you're further than that from somewhere you can get a tire, slow down, put on your 4-ways, and keep going.

      The damage to the lire, under the circumstances you cite, is likely to be the same. But tire manufacturers have to provide direction that consumers will understand. Which is likely why most manufacturers, such as Pirelli, recommend that the tire be "retired" after one zero pressure use.

      Can you imagine someone taking a run flat tire, run at zero pressure for 30 miles, having it plugged, and then go tracking with it?
      I agree; it's more likely to get damaged the longer it's driven without pressure. I'm just curious how much that damage is, after a certain number of careful miles before repairing it. I'm also wondering what the failure mode would be if driven hard (not track use, but regular 'spirited street' driving). Without more information, I'm inclined to believe that it's the manufacturers 'covering their butts', as previously mentioned. There's probably a good amount of safe use left in the tires for normal use if plugged within a reasonable distance more than once. (Use, not abuse). If I were in that situation I'd probably do a good visual inspection of the tire for damage, and make the assessment.

That being said I prefer to have run flats for the simple reason that if I do get a flat I can choose the location of where to address the issue-simply a comforting safety factor in an uncertain world-especially if my wife or other family member is driving alone. I always carry a patch kit and compressor for my run flats and have repaired them without issue in the past-but I immediately addressed the loss of pressure and did not keep driving more than the bare minimum. Most tire places won’t repair a run flat, but a regular mechanic might-simple business practice
        You make total sense. Excellent advance planning!

Not a problem it was never driven on at low air pressure. Saw the low pressure warning and fixed it in the garage.

            I bought the insurance through the dealer , they replace it if I get a nail. They said they don't repair run flats. I have bad tire luck so I figured it would be a good idea .

              Same here. Our dealership no longer repairs run flats. Thank goodness we had tire insurance.
