Have it inspected at a tire and alignment shop to find out which parts are worn out. Two things can cause inside edge wear. Too much "total toe out" will scrub the inside edges of both tires equally. Toe out can be caused by worn ball joints, tie rod ends, control arm bushings, and weak springs / low ride height.

Worn control arm bushings and ball joints can allow "camber" to become too negative, meaning the top of that wheel is tipped in as viewed from in front of the vehicle. Camber problems always only affect that one wheel, but you can have problems on both sides so both tires wear the same way.

You can also have that wear pattern simply from incorrect ride height even when no other steering or suspension parts are worn. A vehicle can be aligned and show perfect numbers on the computer, but when ride height is wrong, it changes the geometry of the suspension system and the movements the wheels go through as the vehicle goes up and down over bumpy roads.

If you start randomly replacing parts, you'll add a bunch of variables that change the alignment. That could make the tire wear worse. That's why we always start with an inspection to identify only what needs to be replaced.
