Inner tire wear in the back only

[jfchnet]

Hi all

I just switched to winter tires and I took measurement of the original tire wear, and I was shock to see that in the rear, the inside is more worn out than the outside.
I see the exact same wear on both rear tires. I was on a trip with our small travel trailer, with all the gear and people, we were nearly max payload for 2 months for around 10k miles.
Could that cause that kind of wear ?

I have a Ram 2020 limited, 19K miles on it.

Is there an alignment that can be made in the rear ?

Thanks in advance

You can get a 4 wheel alignment

Some thoughts
1) Are you sure those tires were on the rear? You didn't maybe mark where they should go when you removed them last Spring, not where they came from?
2) There are no adjustable angles on the rear axle. It's a solid piece. You can -- and most likely will, without it saying as much -- get a thrust-angle alignment where it takes into account that your rear axle may not be perfectly perpendicular to the centerline of the truck. The front will be adjusted to match the rear. But that doesn't involve any adjustments to the rear.
3) Underinflation wear should affect both edges equally.
4) If the rear axle was skewed, you'd likely see wear on one inside and the opposite outside edge. That doesn't sound like your case.
5) Both inside edges worn would be a sign of negative camber. This could be from misalignment or just plan sagging. Less weight on the front means it lifts and the tires pivot so that the outside wears. Heavily loaded, it does just the opposite. This is if the tires came off the front.
6) It's possible that you really overloaded things and caused the rear axle to bow which would wear the inside edges. But I think you would have to have really, really overloaded it.

#1 is an interesting theory, I would like this was the case, the solution would be very simple! But I'm 99% percent confident they came from the rear (Girlfriend helped tag them as soon as I removed them from he truck)
#2 that is what I though and being afraid of.

#6 From your picture, it the wear fit perfectly the overload. but for that to happen, the axle has to bend. The truck was beavering perfectly fine, like I said, we did a cross country trip, so a lot of driving. If it was unbalanced to the point of bending the axle, I hope I would have noticed. I know that I was flirty with the 7100lbs GVWR from the stop to the scale I made at the beginning of the trip. The cargo pretty much stayed the same all the time. So account for some 'souvenir' maybe we went to 7200 or 7300, but I cannot see anything much more than that.

Thanks for the replies guys!! Love to get your ideas on the issue
