Same reason you run big tires in the rear of your Duster. For grip. :roll:
Lots of new performance cars with less weight in the front have that 275 wide of front tires.
275/40/17 will fit a stock suspension if you can get the backspace around 5.25" or more with a 17x9 rim. You probably have to roll/cut/fold the front lower fender lip. Like what's talked about in the thread listed above. Problem is I don't know if an Alterkion can take that much backspacing. Best to just ask Bill Reilly.
