Tires are feathering
Ever since I got new tires, all four of them have been feathering. More on the outside than inside, but definitely on both sides.
I don't recall it happening with my old ones....but its possible that they did. I recall bad wear on one of the front tires, but it was due to a bad ball joint.
I've done everything in the book to battle the "wander", so the front end is pretty solid. New Bilsteins all the way around, Pitman arm, tracking arm bushings, sway bar bushings, tie rod ends, ball joints, steering box, etc.
Just had the alignment checked and its solid.
Any ideas? Happening in the rear as well. In fact the tires in the pics were on the rear until a few thousand miles ago.
FYI - tires are the OEM Pirelli Scorpions.

My first take--as it seems to be bilateral--would be that the tire pressure is a bit too low.
Get a big piece of kids' sidewalk chalk, and rub the side of the chalk against a 3 - 4" wide section covering the tread from side-to-side in about the same place on both the front & rear tires. Drive the truck forward until the tires have left a latent chalk print on the ground, and check how the contact patch is being transferred to the ground. If the outer treads (shoulder) are much more defined & imprinted, this would confirm a low inflation diagnosis. If you have a portable air compressor, add a couple pounds of pressure, and repeat the whole process with the chalk.
Keep in mind that once you use the chalk method to find an "ideal" tire inflation point, that this is only an "ideal" inflation for that vehicle in its current configuration. If you often throw a bunch of camping gear in the back, a boat, a camper, or whatever, you will need to repeat this with that load to get an idea where to inflate the tires to match that load.
