What can be making the inside of my tires go bald on my front tires but not the outside of them?

You need a wheel alignment. Camber is the vertical angle the tire makes when viewed head-on. Since your tires are wearing on the inside, you have negative camber. Take it to a good alignment shop and get it adjusted properly.

or just eyeball them for now till you get them perfect, put steering wheel straight ahead, sight the front tire parallel with car body straight ahead , now do the other side same way, one will be likely aiming out called toe out, loosen lock nut on the tie rod of the bad side, turn tie rod in or out to draw it in line and re-lock the nut ,about 17 -18 mm open wrench. that will save the tire from wearing out and going flat witch happens very quickly, look for steel cords [sharp] exposed

I have a 2002 two door dodge stratus and my front tires r also wearing out on the in side and the two balts that r on the strut to the spindle do not adjust so how do I line it up tires on top lean in and out on the bottom
