Irregular Drive Tire Wear?

I've had this truck since July 2012 and in the last few months, the tire wear has become very much evident, this wear is on all 4 inner duels. Tire pressures are inflated to 100 psi with all tires within +/- 2 psi. All the same wear pattern. I have been to multiple shops and have had many different diagnostics:

  1. One was that I had bad shocks.
  2. Another was that I have an alignment issue.
  3. Another was mismatch tire pressure.
  4. Then I heard that it could be loose bearings.

I bring my question to solutions to see if anyone can help me not throw money all over the place and not solve anything. By the way these are XDA 2 Custom Molded recaps. I plan on new tires but before then, I would like to solve this issue. I have uploaded photos to show the wear.

''First I would bump the tire pressure up to 120psi and see if they start to flattening out. This should not hurt the tires. I run my drives at 125-130psi all the time and have never had any problems. In my opinion 100 psi is too low. Tire usually fail from under inflation not over inflation. If this wear pattern continues I would take it to a heavy truck alignment shop and let them look at the tires and check and see if the axle housing is bent or warped. If a truck is used in a heavy haul application over a period of time the Banjo housing can and will bow causing the inside tires to wear more than the outside tires. They can check them for being centered at the center of the axle.

Note: If you raise the tire pressure it will help on your fuel mileage but it will also allow it to break loose in wet weather conditions if you over brake so be careful.''

Ok. thanks blackwood777. I greatly appreciate the tip. I pull a reefer, so the weights can get up into the 77k GVW range at times and now that I think about, the 100psi might just be to low. I will try bumping the tire pressures up and see what that does. I will keep posting updates here.

I think your bearings are to loose with inside wear you have.

ok. Thanks a bunch Pete A. I will have a shop check them out. I know the left rear axle bearings have been replaced, but dont know to what specs. However the wear is still there. But I do believe that since they have started this wear the tires will just keep this pattern and wear that way until replaced.

Thank you so much Jerzy Z.. I just called Chad and he told me that my tire wear is coming from lose bearings. He said that its the most under-educated and over-looked basic maintenance item on a truck. After home, I'm heading right out to his shop to get it corrected. Thanks again.

I second the axle bearings. I re-torque mine once a year.

Ok Dave. That sounds like a great plan to have them re-torqued or at least inspected once a year. Thank you for commenting and lending a great tip for my problem.

This is not a diagnosis so much as a helpful hint, Grease the fifth wheel and have the trailer aligned as well, seems unlikely to me that you have 4 loose or incorrect wheel end sets, have the alignment checked at a good shop you trust, if possible find someone who will do it with trailer, I see alot of tire wear issues brought on by people who own a trailer and do not keep it greased.

Is there a noticeable vibration when pulling steep grades?

Hey Your, thanks for the question. I do in fact feel a vibration when going grades, but also on flat land.

Bring the truck back to where u got it aligned...or take it to another alignment shop. My guess is the two drive rears are fighting each other meaning they are not perpendicular or square to the chassis. It is shimmed wrong or not shimmed at all. My experience says there are good alignment shops and terrible alignment shops.

Ok. I'm just going to research some alignment shops and ask whast system they use and go from there. I'm going to do that and get new shocks put on and go from there. Thanks Your for the ideas.

Tried adding my own question, but here it is.....sorry for the hijack, OP. Single axle straight truck with tag axle. Inside rib on driver's side is cupping. Worst depth in cupped area is 5/32. All other ribs are at 12/32. Bearing adjustment? Shocks? Alignment? Help! Hate trashing an otherwise great tire for this issue, but won't let it happen twice.

Thanks guys for the input...glad to see the possible solutions to the problem. I have the same problem on my passenger side front and rear inner drives. Going to raise psi to 110 and check bearing torque...would it be a good idea to rotate tires to see if the problem is resolved?

Hey there csarria, that's what I was going to do before buying new tires. I'm also going to replace the shocks just for "tire insurance"...

Were you able to resolve your problem? I have the same thing on my truck. And some kind of irregular vibration. Have spent alot of money to find the problem but still no luck.
