The Federal 595 Evos, including shipping, are a good deal less costly than those Kumhos (even after the current rebates), and at 240 tread wear, are not a track type tire by any means (and actually have a decent water evacuating tread pattern), although they probably will wear quicker than the 400 tread wear PS31s.
Being .5" wider in tread width, (but only .1" wider in section width, and .1" shorter in height) I can see where you might fear some rubbing with a 40 ET, as even I might be close with a 42 ET using the Evos on my wheels.
