Just had to replace some new tires I bought a few months ago, they are wearing badly on the inside, ripping the tread right off. When you look at the front of the truck, the tires are tilted out and causing the wear on the inside of the tire. What would be the most likeely causes?

The reason I am asking is because I want to know if itcould be another reason other than just needing an allignment

 

Tilted out at the top could be caused by a bad ball joint. A good alignment shop will inspect the suspension prior to doing an alignment.
