Is it safe to assume I need an alignment?

[jumboj]

I put some new tires on my truck in 2019 and I got an alignment done afterwards from a place that "specialized" in alignments.
I just did an oil change last weekend and noticed that the outer edge of both tires on the passenger side are showing significant wear(the front and rear tires look to be worn in the same manner and the same amount), they are pretty close to the wear strips, whereas the rest of the tire and the two tires on the driver's side look perfectly fine.
The truck drives straight, it doesn't seem to pull to either side but based on the uniform wear on both tires I'm inclined to think they messed something up with the alignment.
I'm not an expert by any means, but can anyone confirm that it's just a bad alignment or does this sound like it's related to something else?

Thanks for any help

You've got chamber, castor and toe.
All 3 must be within spec.
Plenty of incompetent alignment shops out there.

How many miles are on these ~5 year old tires?

5 years is a long time and an unknown amount of miles. I'm thinking it's possibly just normal wear--every time you corner, outer edges take more wear.

Trucks usually are solid axle in the rear and I'd think unlikely to take wear like this, leading me to think it's from cornering, not alignment.

How many times have they been rotated? If several, and they were rotated front to rear, all wear might be attributable to the front passenger alignment.

Rotating your tires correctly would help... it's normal for front tires (steering axle) to have a little outer cupping which is why you always want to criss cross them when rotating to have that little bit of cupping go the other way to keep the tread wearing evenly.

Most tire manufacturers recommend rotating the tires around 6k to 8k

I change my oil ever 5k miles so every second oil change I rotate the tires and they all wear even and they all looks the same.

^^What you show for FWD is what I do.
My tires always wear evenly and straight.

The tires have approximately 33,000 miles on them and have never been rotated. I remember when I bought the truck and was reading about tire rotation, I found several sites that said if the tires were wearing evenly tire rotation was not necessary. I got approximately 68,000 miles out of those tires before I needed to replace them so that all seemed logical to me. I will admit that I haven't paid much attention to my current tires because of how long the last set lasted.
There is a bit more wear on the outside of the driver's side as well, but it's much worse on the passenger side.
What I'm gathering from all of your responses is that I should definitely be doing tire rotations.
Does the fact that there is quite a bit more wear on the passenger side indicate that there is in fact an alignment issue?

Not necessarily. Right turns are tighter than left turns, and so this can cause more wear on the right side.

Another good reason to rotate your tires.

Chamber ---> Camber
Castor ---> Caster

You didnt post any pictures so anything would be a guess..
and you know what ASSuME means.

That's the idea, and rotating helps you get maximum mileage.

I found several sites that said if the tires were wearing evenly tire rotation was not necessary.

NONE of the tire companies that make tires says this... they all recommend rotation about every 6k to 8k miles.

Only one way to find out.... take her in for an alignment!

you know what ASSuME means.

That's weird... Ass You Me?
Is that how the kids talk these days?

To ASSUME makes an ASS out of yoU and ME ... goes back a few years, way, way before the kids of today, and apparently you, as well.
