Your problem is the allingment. This is a very common problem with all cars. In your case the upper control is adjustable and sometimes moves causing allingment issues. If you notice the upper contol arm has a bolt on each side that the washer welded to is not centered. This allows the upper arm to be move out or in. After time they tend to move a little. It doesnt take much but once it starts it will never go back. Hitting curbs alot will cause this, also heavy offroading. An allingment shop can cure your problem.
When raising a vehicle by doing the TT (torsion twist) you are also making your allingment go out(bad). Cars are allingned by there ride hieght and once you change that by lifting or lowering, you are guaranteed to need an allingment.
One more thing, I always reccomend an allingment when getting new tires. If your tires are wearing fine it still doesnt hurt to just check it and see what the allingment machine say. Your tires will last a heck of alot longer with proper air inflation and a good allingment. I have got over 60K miles from a set of 31" BFG AT.
I have to respectfully disagree with several of your statements, and here's why:
First, an Explorer's laognment cams should never move a little after any amount of time. Other items may wear (bushings, ball joints, tie rods, etc) but the alignment cams that hold the upper control arms in place should never EVER move. If they do, they weren't torqued properly to start with.
Second, raising the vehicle with a torsion twist will not necessarily cause an alignment problem. I would not make that guarantee based on my personal experience. I've done it to my F150 and Explorer, as well as several other friends' Explorers and F150s and none of them has ever required an alignment afterwards. In fact, both my Explorer and F150 were in the shop for new tires a week after doing the twist, and I had them check the slignments on both. Both were well within the manufacturer's specs.
If the alignment was originally set at a particular ride height, and the vehicle has sagged as the torsion bars lose some spring over time, cranking them simply returns the vehicle to its original ride height and, therefore, the alignment should be right back where it started from. Why would it change?
Finally, as you mentioned, proper inflation, alignments, and regular rotation can maximize the life of your tires. My last set of tires (Michelin LTX M/S's) were just 62 miles short of 100,000 miles when I replaced them a little over a year ago.
