Opinion's on What Is Causing This Tire Wear ?

[HenryMac]

I rotated the tires on my 2019 Ranger today. I've rotated them every 4,000 miles. Truck now has 20,000 miles.

These are the Hankook DynaPro ATM tires that came on the truck, dealer ordered them as LT tires.

All 4 tires have the wear pattern shown in the photo's below, and the inside tread has the wear pattern, but not then outside tread.

Tire pressure shown on the door placard lists 37 psi, and that's what I run them at.

Thoughts?

Tire out of balance/ sloppy suspension

I think an alignment issue causes that. It's either that or something is up with the suspension.

 

[Roert42]

It’s called cupping

Shocks. Probably made in China.

+1 ^^^

Called cupping or scalloping
Can be worn out/broken shock allowing wheel to bounce more which you often don't feel in the cab, where you do feel an out of balance wheel

Alignment. Tires are toed out. Normal alignment settings have a tiny bit of toe-in.

Most likely it is an alignment issue. My experience is that the factory "allowable" range for alignment is too wide. Some tires require slightly different alignment that others to avoid irregular wear, and the tires pictured are in that category. While the truck may be "within spec" according to the factory range, these tires need slightly more toe-in and/or slightly less negative camber to avoid that kind of wear.

Thanks... that makes sense. These tires were on the truck when we bought it new.

We bought a set of these same tires for our '02 Tacoma back maybe 6 years ago. I always rotated them every 4,000 miles, and they would start "talking to you" at freeway speeds near that 4,000 mile mark. We had the alignment checked and it was "within spec". When we traded the truck in, the tires had 57,000 miles on them.

Ask the alignment place to set it on the tighter side of the allowable range

Normally I would agree. Since the truck is still under warranty with the original tires and I don't remember @HenryMac doing much in the way of modifications, I would go that route and try to get Ford to pay for it. The truck is only about 2 years old and shouldn't have suspension and/or alignment problems already.

Alignment is only warrantied 6 months because it's so easy to knock it out, a curb hit, major pot hole, etc. If all the tires are wearing on the inside edge it either has too much toe out/not enough toe in or excessive negative camber. I would find an experienced tech and request the alignment set to "preferred", and also request a printout. I hired an experienced alignment tech who had worked at a tire store for decades. He was really fast until I found out that he was getting them "in the green" and shipping them. Everything can be within the tolerances and it will wear tires badly.
The wear pattern is called heel and toe wear, we called it chop, and can be mitigated by crossing the front tires to the back and bringing the rears straight forward. Just rotating front to rear does not do it.

Thank you for taking the time to write this ^^

To clarify, I have rotated them as shown below, crossing the front tires to the back and bringing the rears straight forward, every 4,000 miles for 20,000 miles. Every tire thus has the exact same wear pattern. The fronts are always worse when I rotate them... but then again... that's why you rotate tires.

No curb hits have occurred, nothing that would knock the truck suspension out of alignment.

I am retired, and have a 2 post lift in the barn. Routine maintenance is something I take pride in and enjoy doing. I don't take my vehicles to the dealership or to any other service shops unless I can't personally do the work myself because experience has shown me I'll do a better job than they will.

I will likely take it in for an alignment though. I did that very same thing on my Tacoma, when the Hankook's on it were showing the same wear. It was in spec. (in the green), but now that I know the alignment needs to be even better, I can work with them to make that happen.

Truth be told, the heel and toe wear isn't a big issue, it's more of an annoyance due to the noise. Like I said previously I got 57,000 miles out of the last set of Hankook's. Our Tacoma had 175,000 miles, so we just figured that was to be expected.

I just expected better on a brand new vehicle.

Improper tire inflation is also one of the reasons why a tire wear out fast.
