As far as the front tires wearing first, yes. Think about it, you turn with the front tires and they are the wheels that spin first to get traction. Thats why you're supposed to rotate your tires every other oil change or so.
But for your situation, sounds like there is another problem there if you got them only back in June. Doing burnouts often, have an alignment problem? Proper inflation?
Although the point has already been made, what is the treadwear on your tires? Remember, a lot of ultra-high and max performance tires have very low treadlife. And that being the case, if the wheels aren't frequently aligned then the tires will go bald even quicker.
I always drive the piss out of my car and never had issues with the edges wearing out except for the when the toe was out of spec. I ususally get an alignment at least once a year, sometimes 2-3 times depending on how the car is handling.
