I have the same on all my cars, past & present, sedan & minivan alike. Different forces (mostly braking) exerts more force to the leading part of the tread, causing it to wear more, hence the sawtooth shape.
Spoke with different manufacturers, same response. I wouldn't worry as long as the tires wear evenly in general. Just rotate them regularly, if not directional+staggered.
