Mastercraft M+S tires w 1500 miles, worth anything?? too loud!

my truck came with the off road package wheels and tires, Mastercraft Coursers M+S 245/75 R16's, i do 100% highway driving, and a lot of it, around 20,000 miles a year... these tires are incredibly loud.

im thinking of going to a highway all season tire, Michelin LTX M/S2's. its prob going to run me around $800 by the time its all said and done.

The tires came on my truck were brand new, they have 1500 miles on them now, do you guys think they are of ANY value? if i could offset my tire swap, it would help me make my choice of either doing this or putting it off.

what do you guys think...

im also thinking of calling my dealer and asking if they will help me out here, but im not counting on since this is really my problem, not theirs...
