Hmm. Biggest problem is damage to the carcass. Car tires flex mostly  
in one dimension being flat from sidewall to sidewall. Bike carcasses  
flex in 2 dimensions making a plug much harder to stay put and putting  
far more stress on cut cords. I have plugged them with good results  
but I'd feel better with a plug-patch combo. You COULD put a tube in  
it, but who has them anymore?

I had a failure last week - first front I've ever lost on the street.  
Expecting a screw I almost just put a plug in, but having spare  
takeoffs (Supercorsas) I just grabbed on to swap. Good thing - a steel  
cord had broken a couple of wires and punctured the inner layer.  
Apparently my 80 mile daily commute is a bit much, I've never seen a  
failure like that before.
