Hello everyone. I’ve just turned over 36,000 miles and am experiencing inner tire wear. Overall across the tire looks good. But the inner fronts are warring heavily on ever other tread. I’ve rotated them around every 5k so at this point all 4 have this issue. At 30k I got an alignment but still feel that the issue is present. Any ideas? Trail boss factory suspension and tires. Also I keep the pressure that the maintenance techs put in at 40 lbs. Thanks y’all!

Can you show pics? I ask because you mention every other lug is wearing. That is very odd to happen due to being out of alignment. These tires have alternating lug size at the shoulder. One set of lugs might be softer than the other set though.

Did they give you a printout of the alignment specs, the TB calls for -0.1 deg. camber (non TB calls for -0.4 deg.)
No issues yet on my Ol’ lady’s TB but less than 1K on the OD, plan on doing 2 leveling kit and set the camber to 0.0 deg., that’s where I run my GMC and always have had perfect tire wear…

I am at 33,000 and have the same issue. I rotate every oil change, and noticed between one of my rotations the tire noise was more than usual. I noticed the wear at that time and dont expect these tires will make it past 40k if I am lucky.

Thank you for the replies. I do not have a spec sheet. And here is a pic. My worry is that my next tire will have the same issue. Notice the tread in the middle next to my hand. Worn heavily

Once it's happened to that extent, it's going to be 'bout impossible to correct those tires. If your camber isn't visibly negative, then it looks like a little too much toe in, most likely.
Always get the before/after printout of an alignment. At least you can begin to understand what was wrong, what was corrected and what may still be not right.
If your alignment checks out and you're interested in putting a bunch more miles on those tires, I'd have them flipped outside>in on the rims. Then try to run them primarily in the direction that normal tread "feathering" or wear will take the high spots off. (This is opposite for front and rear wheels) If you haven't rotated them in a while, you'll feel very slight "feathering" of the sipes in the tread blocks. Normal competent tire rotations that take this into account and change rotation direction or stress on tires (drives vs steers) "can" help you get this wear pattern partly back in order. More importantly, you won't be making it worse.

Or buy new tires...
FWIW, the half dozen TBs we have here (company trucks) ALL are very easy on tires, even the Duratracs which generally need attention like any other mudder. I keep up with my rotations, but I know a couple of the managers do not and the relatively even wear with aggressive tires speaks to how well these trucks "generally" are aligned.
