"wound" on the tire side
I would ask myself the question: "Even if it looks like the tyre is ok, do I really want the hassle of the thing blowing 10 miles from home - even if there's only one chance in a hundred - and then having to change the tube, hoping it doesn't re-puncture, all the while freezing your ** off? And probably in the dark too. And even then, when you get home, having to replace the tyre in any case."

Compared to the price of a new tyre I know what my answer would be. (I should probaby add that tyres in general are more susceptible in thev walls, which would sway me even more.)

Congratulations for keeping your cool by the way. Your logic seems totally sound in terms of this guy being a psycho but very often adrenaline wins hands-down over rationality.
