The tire hole was extra large, that tire would have been down instantly if the plug pop out, hole in tire was 1/4 inch +If a tire plug works it's way out and totally flies out of the tire, then it wasn't installed correctly or someone tried to plug a hole that was way beyond what a tire plug should be used on. Even if a tire plug suddenly flew out of the tire, it would be nowhere close to a tire "blow-out". The tire would leak air fairly quickly, but it wouldn't be some instantaneous "blow-out" failure.
