when i went to pigeon forge for a weekend, my tires were worn considerably on the outside edges. I knew it was from all the long sweeping and sharp curves i drove around. The ride to cade's cove must have been 45 mins each way of constant turning at 15-40 mph

 

The rears should NEVER wear on just one outside edge no matter how much turning you do. Both edges on the same tire is PSI issue but one edge is a problem.

 

Interesting...my crappy generals did on that trip.

I have kept up my 10k rotations since the trip(maybe 25000 miles ago) and the tires are back to wearing evenly?

 

Cb, how many miles are on the tires?

Do you rotate them with the front axle?

How often do you rotate?

What air pressure do you run? front/rear

 

no i haven't had it off road ever i'm pretty particular about it lol imagine that, no noise at all going down the road either, i don't know i had a bad wreck before i even made the first payment on the thing, some old women pulled out infront of me and i swerved and she caught the rear drivers side and i'm thinking thats got something to do with it? it did 17,000 $ worth of damage the body shop had it for two and a half months, it sucked i had diesel withdrawls! maybe they didn't fix it right but it didnt wear like this on my last tires?

 

With this new information, I'd check the bolts that hold the rearend to the springs. Also look at the springs to see if they're shifting or separating. The center bolt may be broke.

 

Have you checked the bushings in your rear springs? You may be getting a little movement in the spring shackles.

 

Is the rear diff locked?

 

Now you tell us!.... LOL. I'd say if it was wrecked then something is either out of alignment since it happened or something was damaged and recently moved. As stated check leaf spring center bolts as well as U-bolts. Axle may have twisted inside the U-bolts under load if they were off for something and not properly torqued by body shop. Make sure the shackles aren't bent or anything either. Might want to take it to an alignment shop - large commercial truck places can align all the axles and could probably check yours better than a standard automotive shop.

 

that's kinda along the lines i was thinking to,it has something to do with the rear end it about has to be....

 

Does the truck track straight going down the road, or does it pull left or right? Depending on where you were hit, it is really weird to have both rear tires wear exactly the same. How many miles has it been since the wreck? If it hasn't been too long, then I would take it back to the body shop and have them do another alignment, or take it to your Dodge dealer. It is possible to do a supplement from your previous wreck.

 

it really doesn't pull one way or another that i can tell, she hit me on the rear drivers side little over two years ago and 30,000 miles later, i had a set of bfg all terrains before i got these pro comps and they wore like this too noticebly on the back, im taking it to a shop monday and see if i can get it looked at and going to get the tires rotated and the front end allinged, i just got that feeling it s something in the rear end....

 

Take it to a frame shop and have them check the frame measurements first. That is where I would start. I know the frame is not likely the cause, but it is the easiest to rule out. Any good frame shop should check for little or nothing.
