[QUOTE="Rustler, post: 1552162, member: 31456"] @smufslayer I think we're talking cupping, not feathering. The uneven pattern is every other tread block wearing on the inside band as you move around the circumference of the tire, not uneven wear across the tire from inside to out. See graphic below. what I am seeing is more like what it describes as "scalloped wear." Also, there is another pic from a Tacoma forum below. It's a duratrac off a taco, but this is exactly what my tires look like. Here's the forum post: [URL]https://www.toyota-4runner.org/5th-gen-t4rs/238476-whats-causing-my-duratracs-cup.html?s=f473d652fc8943526741360de617e515[/URL] I think your right that the "heel and toe" wear (more wear front to back of each treadblock) is a common occurrence, and that would be exacerbated by the failure to cross rotate, which would change direction. I was incorrect about the cross rotating moving the inside to the outside. As you point out it would change the direction of travel, but not move the inside of one to the outside of the other. I see a lot of references to both worn shocks and alignment causing this issue. Keep in mind that the truck was aligned by the dealer, and reportedly aligned on spec with no adjustment. I am interested to see the paperwork, but the truck was dropped off at my house while I was at work, so I haven't had a chance to see it yet. It is entirely possible the noise and the tire wear are not related. It could be that the tire wear is a function of not cross rotating, and not doing it frequently enough. I will rotate at 5k moving forward in any event. Thanks again for the time and input! Happy to hear more ideas![ATTACH=full]154198[/ATTACH] [ATTACH=full]154199[/ATTACH] [/QUOTE]
