I am perfectly knowledgable of tires and treadwear. The tires say to fill to 80psi but I only fill to 50 to 55psi and they are flat to the ground with a flat bulge to the ground so i know they are not overinflated just by looking at them.
I know tires, I would never over inflate my tires. I have a very flat profile of tread on the ground. Thats why if I go much lower I would start getting more wear on the outsides of the tread and make even more noise and lose more MPG
The tires don't say to fill to 80psi. That is the MAX inflation based on the MAX load.
I had 60,000 miles on my last set and they looked perfect when I replaced them with no uneven treadwear. There is more than psi to factor when airing tires. The weight of the vehicle and accessories also dictate tread to ground contact
You put 60k miles on the last set on your 2018 4runner? Another 5th gen 4runner, or a completely different vehice (10,000 lb dodge ram cummins truck you mentioned above)?
55 psi on that truck makes sense. 55 psi on a <5,000 lb 5th gen 4runner with E rated 33s does not.
