That wear pattern is not from lack of rotation. He’s got other issues.
X2 on Blake's comment. Guess it's a jeep thing, and I wouldn't understand
Those wear marks are definitely from a worn out suspension/steering. Used to get the same thing on my first gen when my tie rod ends would fuck up. But pretty much any worn out bushings/suspension could cause it.
Interesting. I hadn't really thought about checking anything else. I know the outer tread will feather with time. I just figured he let it go so long that the inner blocks started to feather as well.
