Weird tire wear, thoughts?

Have tried swapping tire and rim positions?

 

If its just the one tire it COULD be a very slightly bent rim. I have run into that before. Easy way to rule it out is to move the rim, if a tire wears funny in the new position trash the rim and get a new one.

Otherwise id still start with an alignment after moving the rim. It rules out like 95% of common issues. For example if you curbchecked that wheel it may have slightly knocked it out of alignment or something. Its a cheapish way to rule out most issues. If it goes away great problem solved. If not then we start getting to expensive ####.

For example that pattern looks like when i had a shot wheel bearing, easy way to check is spin it while its jacked up for an alignment and moving that rim and see if it makes noises. Wont always make noise if its shot, but if it does there is likely a good chance it IS a bearing issue. That said though it could also be a slightly bent spindle if you whacked something just so.

 

That suspension hanger looks like its rotted out pretty good.

 

I believe that's from mismatched tires. They have a different tread pattern. The inside might be a tad shorter.

 

You would be suprised. My pete was slightly out of alignment and would only ever chew up the one tire because it was only off a bit. Didnt matter if i put 2 new ones on, moved rims ect. Kept cheewing up my inner tire. Then i got it aligned and the problem went away.

Same with a bearing. Had one on my drop axle going and it kept eating my outside tire. Replaced the bearing and it fixed the issue.

There is a reason an alignment is the first recomended step by many though. You would be AMAZED how often that fixes all kinds of weird issues. And even if not. An alignment never hurts anything and rules out most common and a lot of uncommon amd rare tire wear issues.

Good catch, i missed that entirely.

 

All of the above. Definitely check wheel end play. May just need to tighten up bearings. Usually the inside tire will wear more in the same way. Being mismatched, ???? Easiest things to check, along with a bent wheel. Jack up, try to move it back and forth, see if it’s loose. Then spin wheel, with a big socket or anything up against the wheel. Bushings? Might notice it dog tracking a lot. Often intermittently, depending on where the arm is at while it’s moving around. Alignment? All three?

 

That’s what I was thinking. Mismatched tires and likely the inside tire is taller. TA put a 11R next to one of my 295 75 lo pro and the 295 was completely bald after one day running 75mph.

Yep, shorter tire takes a beating. On mine it’s always flat spots. Maybe from bad shocks? Also any time I put a used steer with inside wear, wouldn’t last long. Once the pattern’s established, that’s it. A tires only as good as it’s low spots. The exception is drives. For some reason, a used steer with established inside wear on my drives will run a long time without getting worse. Something to do with torque pressure vs. free rolling trailer or steers, is my guess.
