What's causing this tire wear pattern? Alignment or tire pressure?

2017 TRD Pro with about 500miles on new Wildpeak AT3W's (LT 275/70/17 C-load). Just today I noticed what seems like the beginning of an uneven wear pattern. Only seen on 2 tires, mainly the front drivers side, and slightly on the rear passenger side. The edges look and feel scuffed versus the smooth feel of the rest of the tread. Front alignment was done when the tires were put on. Prior to the alignment, I was had pulling to the right, but gone since then.

Shop initially set my pressures to 35psi all around. To make a long story short, load inflation tables and advice from others using LT tires on the 4runner lead me to believe that 35psi was the absolute minimum pressure for using an LT tire on the highway, and that technically I should be around 43-44psi all four corners. Did that for a few days and had vibrations through my seat (none in the steering wheel). Dialed things back a bit in the rear and vibration was gone. Did a little more reading and ended up with 40psi up front, 38ish rears (no cargo load).....but here I am now pretty much back at square one.

Rear Passenger is definitely alignment.

Why do you say that? I'm trying to understand what's going on if/when I have to go back to the shop.

It APPEARS that your front pressure is too high. It looks like you are not using the outside edge of the tire. Meaning that it is crowned in the middle from too much air.
Other peoples advice and "charts" are starting points to determine YOUR proper pressure.
Find an empty parking lot. Get a stick of chalk, rub a 5-6 inch wide section of the tire across the WHOLE width of the tread and then drive STRAIGHT for 20 to 30 yards, more if space permits.
Then look at your tires, see any chalk on the edges of the outside tread blocks? If you do your pressure is too high, for your tires on your truck.
Do this process front and rear and then see if the wear issues go away.
Depending on where you live, ambient air temp should be ABOUT 1/2 the temp daily range. EG: 40* low and a 70* high, try to set your pressures at about 55*
And make SURE you are setting COLD tire pressures!!!
Good luck

What's the rear toe spec? The p/s toe is 5 times the d/s according to your print out.
I have a Toyota Matrix, an '07. When it was "young" the original rear tires developed a loud hum. Took it for an alignment and rear tires had a toe problem even though in spec and were cupped on the inside like yours looks. Toyota said not warranty, rotate your tires as suggested and you won't notice it. They were right and that may be what you have to do if the rear toe can't be adjusted.
What is your tire pressure? That should be easy enough to eliminate and that won't cause cupping on one side of the tire anyway.

Too much pressure.....crowned in the center. Try 36 all around for a week and see if you use all the tread in daily driving.

I'm lost...the outer edges are the areas that are more worn. Looking at the tire, I initially thought it was the middle of the tire that was worn (because of the darker color), but looking closely and feeling the tread, its actually the outer edge.

If you look at the 3rd tread up in the 1st pic, you can sort of see what I'm talking about. The rubber looks like its frayed/scrubbed at the edge. The middle of the tire almost feels like its brand new.

The 5th generation 4Runner has a solid rear axle, thus there is no adjustment for rear wheel alignment. If the rear tires are out of alignment, the axle is bent, which virtually unheard of.

Since the tire molding nibs are not worn off yet, it is hard to diagnose wear patterns. Looking at the nibs, they are worn at an angle, not flat, which could be alignment, but also aggressive driving, especially cornering.

P.S. There is no mention of rear tire alignment specs in the factory repair manual, only front tire. TOYOTA 2016-2019 4Runner Repair Manual RM27F0U

As others have said, it looks like over inflation, and possibly worn shocks.

Having both outer AND inner edge wear would indicate UNDER inflation.
Like AMLOR had mentioned, you should do the CHALK test. Youtube is your friend in this case - look for a video that shows you want you should be doing to set your PSI by using chalk. Essentially, you "color" a section of your tire with chalk. Then, start with high PSI and drive (in a slow and straight line). Keep reducing the PSI until you see that the all the chalk has come into contact with the ground.


Good luck!

Yes, underinflated if the outside and inside is worn more than the inside.

The outer edge will look feathered from scrubbing when you turn, but the center never loses contact so it is smooth. Chalk it and drop pressure to get a full contact patch .....

40K miles on my AT3Ws, stock size in SL. All 4 tires are slightly feathered, alignment is fine, rotated every 5K miles. Been running around 35psi cold, per Discount tire such wear pattern for an A/T tire is not unusual. Not sure if I buy that explanation but... Other than that I like the tires and will likely replace them with another set of the same thing.

Too much air pressure IMO. Try the luxurious feel of 32 psi in front and 34 in the rear. That wear pattern looks like its wearing in the middle and not at all on the edges. Lower air pressure will allow the entire tire to contact the road, meaning the edges too.
