Odd tire wear, possible alignment issue(s)?

[aero319]

Hey everyone, I’m testing the waters here..
I have an issue with my ‘22 Lariat AWD (2.0l) where my rear right tire has worn exponentially faster than the other 3 tires. The tires are relatively new, <1 year old / 20k miles, and are BFGoodrich Trail-Terrain T/A 235/65R17/XL 108T tires.
Off the bat, I’ve noticed that the rears wore faster than the fronts, which I thought was odd since the front wheels provide most of the propulsion. But, within the last 3 months, the rear right has been wearing down at an extremely fast rate, and primarily on the outer side of the tread. Notably, the wear is not completely uniform throughout the circumference of the tire, but it is close to it and no cupping can be observed.
Now, the redneck handyman in me would suggest this to be the result of too much positive camber, but I can’t seem to find a means to adjust this nor any reason why it would have just started out of the blue.
So I’m here to crowdsource some ideas from you all, the hive mind. Thanks in advance for any constructive suggestions you can offer!
*For reference, the first two photos are of the right rear tire in question, and the third is the left rear tire for comparison.*

Rear tires are not driven tires, so odd wear pattern indicates alignment issues.
Take it to a reputable alignment shop and have them check all mechanicals, nuts and bolts.
If it has been curbed or you found a deep pothole, well, now it's bent under there and some rear suspension components may need to be replaced.

I noticed the same thing at rotation - backs worse, right back worse yet.

When I had a sudden pull start, I took it in for alignment after some time - they found no issue - they tightened up the front toe though.
It was after another rotation I'd done, and putting a very new replacement tire wherever it ended up now caused a pull. It had been on right front with no issue for over 2K miles. Went to back right. hmmm.
Or maybe it was the now more worn back right going to front left. hmmm.

But their before/after normal report showed the back right was off compared to left - still within the wide spec range but other end - but the likely reason.
No adjustments on back.

I think there's another thread about a member having a problem with the right rear wearing unevenly.

I looked this one over, but he’s got the 2wd hybrid so the rear is totally different. Thank you though!

I’m not experiencing any pull at all, so idk..
Additionally, it looks like you have the hybrid—is yours a 2wd then?

I have the AWD, so the rears are driven, albeit intermittently. I also don’t know of any specific events of any acute trauma to that wheel (curb, pothole, etc.) that could’ve caused anything to have gotten bent.

Sorry

No worries, I appreciate any insight that folks can offer!

Is that just aggressive cornering wear? Most people corner harder in left turns, affecting the right tires more than the lefts.

Kinda looks like the tire has a slipped belt in the carcass....

 

[dalola]

I would say you have damaged suspension component(s), and/or alignment is bumped out of spec.

Time to find a reputable alignment shop....

I put 65K on my OEM AT3W's, rotated every 5-10K, perfect wear patterns, FYI...

Somewhat similar to my nephew's tire wear who threw newspapers. Always drove same directions around cul-de-sacs. Helped some to rotate tires every 1500-2000 miles.

Yep.

And I had no pull either despite back toe being at the range extremes.
That tire after 2 rotations just had more wear. I tracked the /32nd's in my notes.

Wasn't until that thicker much newer tire was put on back right, and/or more worn tire was put on front left - then it pulled.

I even took it back after the alignment and said it still pulls.
They swapped front tires and felt it stopped.
It did seem to.

Funny I was in NY for long trip when I slashed the tire, and requested another OEM version - which is less tread than normal, which I wanted - they ordered and installed the thicker commercial version. Same price, so I guess that was nice. Maybe I'll get a rim and make that newer one the spare when I have to get new tires.
I put on front right, and no pull the 1300 miles back home, or thereafter. Until the tire rotate, actually after that it was noticed, so I thought I hit a pot hole bad, didn't associate with my rotation.

FYI. On Michelin web site (there because of my 225/60/r18 lariat OEM tires) not on the site any longer but those tires called for rotation when uneven wear detected or 2k-3k miles.
Warranty called for matched sets of Ford OEM or Toyota OEM or after market primacy. (To eliminate possible issues). Tread compounds and who knows what other differences would affect wear maybe the additional 1/32 or 1.5/32 of different tread depth alone would be a factor. Always have been told to replace tires in pairs with the deeper tread always in the rear due to hydroplaning safety. Traction control possibly could affect tire wear as different number of revs/mile. Might want to check for uniformity of brake pad wear also?
