It happens every now and a again. I still think think the biggest culprit is the "tire" guys who crank on the wheel with unregulated air guns. You can run on 4 safely for a while, but but there's no need to risk it.
If someone over torqued one, they might have all been over torqued. I am
not saying replace them all for no reason however.....
