You guys must not be doing something quite right.
I've been plugging tires off and on over at least 25 years and I've never had that happen, or even anything close. And I've run on my own plug-repaired tires in daily driving, on trips, over rough pavement, at autocrosses, and even for some road course track time at speeds all the way up into the low 1-twenties . . . all with no issues whatsoever. One of my "3-season" 255/45-18 Goodyears has been plugged for about four years. Blind luck isn't going to be that consistent.
