Surviving an explosion of the magnitude that the massive IED generates is somewhat....odd.
Granted the vehicle will have some mine resistance but if you see the size of the blast these IED's produce then the Stryker just drives off as if nothing had happened....has to be a bug :
I would hazard a guess that the vehicle would at LEAST be immobilized. Not just because the tyres blow out but structural damage to the drive shafts, gears, engine and possible suspension units. Maybe the oil filter might get burst too!
