i think in relation to KOV12 and punctures there was one particular rock in hidden valley that could be attributed to 99 % of the punctures at the event. (Excluding Philons!) it was just a characteristic of the route.
As Chris says the smaller the side wall (which is where it got you) the less chance of a puncture. also the narrower your rims compared to tread width and the narrower the vehicle track the more chance you have of avoiding it.
we had a puncture on the shake down in hidden valley with J33P
then another on the actual event same place, same gash in side wall. once i knew where it was we went around it
all front left.
other than that if you run suitable tyre pressures as a mix for conditions and speed and dont drive like you stole it i dont think you will many tyre issues.
we ran Fedimas, with 20psi.
i think MTs would be just as good for KOV if the route was similar to KOV12
last point, its already mentioned, Reliability is the key.
we were slow but steady but finished.
