Has anyone had experience or heard of situations where someone has gone past the speed or distance limits of the run flat tire? I have searched and want to know what happens if I drive over the 50 speed and distance limits. Will my differential be reduced to a mess of molten metal? Will the tire disintegrate to the rims as I continue down the highway in a shower of sparks like on those cops shows? I hope these are precautionary limits and if needed I could for instance drive 80 mph or 100 miles distance without damaging my vehicle.
