Missed matched tires, Hi Pro next to a Low Pro on trailer?

Ok, here we go.

I had a blow out on a trailer tire 12-28-18. I took it to a Petro. Told them I wanted the same sized tires that were on the trailer.

I go home for a few days for New Years, get back on the road, outside tire to the one I replaced a week earlier blows out. Drove about 1,200 miles.

Today I'm looking at the new tire that was replaced Friday and it has no tread on it. When I was a company driver for Knight I ran into this once, where they had a high profile tire next to a low profile and the tire wore about the same. So, I'm thinking they put the wrong tire on. I'm looking at it and outside tire is sticking up at least a half inch higher than the outside tire.

I figure it out, Petro put on a 295/75 R 22.5, I've got 275/80 R 22.5 on the other tires. I call Petro and they tell me it's DOT legal to run these tires next to each other. He claimed they are the same tire. I talked to another trucker and was told 295 is high profile 275 is a low profile. Guy at Petro is claiming there's another problem, it's not that tire.

I'm positive the reason the outside tire is wearing like that is because they don't match. I told him you can see they don't match, he claimed the difference is tread, I'm like no way tread would make a noticeable difference.

Just wondering what your guys thoughts here. There's no Petro TA, WITHIN 200 miles of me right now, honestly don't think I can make it that far, so I'm taking it to loves.

 

The other tires have about 40,000 miles on them. It's a new trailer, that's the mileage I put on it since I got the trailer.

 

The second tire was brand new. Inside and outside tire were both new Friday.

 

I'm positive this is what happened, when I get to loves I'm going to see what they say, and get photos of everything. I'm thinking I'm going to have to put 2 new tires on. Guy at Petro said warranty probably won't cover it, but I can't get to a Petro, like 300. Miles to the nearest one.

I specifically said I wanted same tire on, then asked why I wasn't informed, he said because it's the same tire. I would of never approved them putting a different sized tire on.

 

What benefits me at all at putting on a different tire? At the very least shouldn't I be informed they are putting a different sized tire n, even if technically there isn't much difference?

I wouldn't of let them put it on if I was told.
