weird tire wear problem

[HVAC SuperTech]

I have 305/70/16s as seen in the pics. I have 42-44 PSI on each tire. On the fronts I have almost new tread. on the rear, it looks as though I have 1/4 tread gone. I have less than 2000 miles on these tires. Now, when I bought these tires, he only had 4. so I had 2 put on front, 2 put on the outside rears. The inners are Toyo Open country A/Ts same size but with little tread on them.

Why are the rears 3/32(12/32 front measurement, 9/32 rear measurement) different? wouldnt the fronts be more worn? I dont do burnouts, and we didnt have that much snow this year. the rears do look like they are cupping a bit on some of the tread blocks. I just dont understand it. very little miles on them, but they look worn.

prol from all the torrque of just driving and taking off/pullin trailer put alot of wear on them unlike where the front where weight just sits and steering

I haven't had a trailer behind this truck since the tires were put on.like I said, they have no miles on them practically. Maybe 1000 miles

Measure the outside lugs between the front and the back ones, it should be flipped (or close). And it is true about the torque. Even not doing burnouts, all the torque these trucks put down sure does a number on these tires.

What do you mean measure the lugs? The lugs on the tires? What am i measuring to compare to? It should be flipped how? I am gonna rotate the tires this week. That wil save some of the tread. Also wool show if I get the same wear out of them.

Another thing I thought of, was I had e rated tires in A/T tread on here before these. These are D rated, which use about sidewall strength more than treadwear. But I would think that might have something to do with it.

Sorry, like the tire lugs towards the edge of the tire. and I mean the depth. It should be more worn in the front than in the back. My tires were looking more worn in the back than in the front but when we measured the depth it was just lower in the middle in the back, and lower on the outside on the front. Its kind of an optical illusion.

If I read your posts correctly, You have 1 old and 1 new tire on each of the read wheels? With different weight ratings?

If yes, I would bet $$$$$ its due to the combo, the tires wouldn't be getting even wear just based on differenttread depth, add in different pressures due to thinner side walls...and diferent tread patterns...

I would switch the tires so the 4 matched ones were on the rear....and the mis-matched on the front.

You should have only E rated tires on a dualy, anyway, (Or any 3/4 ton or heavier truck) IMHO.
