Yup, that's the reason.
Some manufactures (Continental I think) will half them only for the rear, while others (Kumho) will half them for both front and the rear.
Consider IS250 have the front wear out much faster than the rear in a staggered setup, I know which tire brand I'll buy and which one I will not buy.
