I have some relatively good tires on my truck.
Over time of course the outside edge rounds out a bit & the fine tread gets shallower from turning corners.
Beyond doing routine rotations I'm wondering if it would be helpful or worth the investment to have the tires removed off rims and turned around so that opposite edge of tires are on outside to extend wear life.
As long as the tires are not directional I don't see it being an issue. After flipping the tires on the rims, road test the truck to make sure there are no issues of pulling to one side (tire pull). It sounds like a money saving idea.
Have the wheel alignment checked to see if there are not any worn parts and if an adjustment can be made to compensate the wear to that side that is worn on those tires.
