Hey all, have 7,000 miles on my 35” tires and noticed the rear are wearing much faster than the front. I know in general the rears of pickups wear somewhat faster due to the obvious reasons of being in 2wd mostly and when turning, especially with loads, the rears ‘skid’ to turn unlike the front which are pointed in the direction of travel. These just seem to be wearing faster than normal. I have experienced this with my previous truck as well. I had a short wheelbase Ram 3500 diesel prior. Had to rotate the tires often as the rear would wear fairly quick. I attributed this to using the engine brake constantly (which obviously puts more braking traction on the rear tires) and the fact that the limited slip diff in the 3500 was aggressive, almost posi like when turning which will obviously cause some ‘skidding’ of the rear tires. I have the exact same tires on my ‘19 1500 and they are wearing the same. The rears already have noticeably less tread. Figured this may be due to the regenerative braking of the e-torque just like the engine brake on the diesel, however, I figured the ‘open’ diff in the 1500 and it being lighter than the 3500 would cause less wear than the aggressive limited slip in the 3500. Not complaining, just curious of any other similar experiences with any other truck, rather it is 5th gen or not. I have the AMP TerrainGripper AT which I know isn’t the best tire out there and that may be the main issue. They are only rated at 40,000 miles but lucky to get 20,000 probably!
Here are a couple pics, you can easily tell the difference between the front and rear. The front still look brand new and the rears have already wore through the first of the three tread levels.

Have the same problem on mine . just had all replaced and the rear where at 4 -32nds and front at 8-32nds rear wear was even across the tread , keep the tires at 60 psi . so it was not an air Problem and it stays in two wheel all the time . And no load on the rear . Did you find out what the problem was ? would be interested . Could it be gear ratio on rear end ? Have the same problem with wife's car and its all wheel drive and front tires wear out at 20,000 miles and rear do not they go longer . griprim12

Old thread - obvious cure to your "problem"
Rotate your tires!
The drive tires are going to wear faster, that's just a fact of life.

I take mine in for rotation ever 5K miles to keep them wearing as even as possible to get the most out of the set.

If the tire itself has uneven wear/cupping/feathering, then there's an issue that needs to be addressed.
