well yesterday i drove about two hours on the interstate down to pigeon forge and came back and today i went out to my truck and noticed that my rear tires was wore on the outside, not the middle or both sides just one side, the outside,this is weird i don't know if it's my rear end out of wack of what maybe one of you fellas can help me....

 

Are both rears wore on the outside edges?

 

yea, on the outside tread facing away from the truck just that side not the inside tread closest to the fender well

 

On each side its the same? That is very unlikely and weird if thats the case. Are you sure they are your rims and tires and no one did a quick switch with you?

 

ha, yea believe it or not, its wild, i think it's something in the rear end, every tire i have ever had has wore like crap after about a year and a half, so you tell me..

 

itr.#1446, that was actually my first thought, someone had to do a swap.
I was also thinking that the axle tube could be bent a hair, both scenarios seem unlikely though. Very strange!

 

How often do you rotate them?

 

is this something you just notice happening or has it been going on ?

 

no, just noticed it yesterday when i came back drove about 70 on the interstate for about two hours down and two hours back, came home went out to my truck and noticed it..

 

Did you have any weight in the truck? What PSI are you running in the tires? And do you have the stock rims, or an aftermarket? Seems with a 12.50 inch wide tire on a 8 inch wide rim, you would have the middle wear out faster...

 

no weight on truck,stock rims, i figured something might be off in the rear end?... is there such thing as getting the rear end alignment? never heard of it, prolly dumb question lol...

 

If they're only wore on the outside edge, (side you can see) on both driver and passenger side, it really seems like maybe the axle tube is bent, with the center being higher than the ends.
If both edges on the same tire where wore I'd blame it on tire pressure.
Tire pressure will cause both edges OR the center to wear but NOT just one edge,especially on the rear.

 

yeah that is the only explanation causing the wheel to have positive camber, if you rear wasn't aligned you would have one tire worn on the outside and one worn on the inside.

 

You didn't have it off-road at any point recently did you? I'm thinking if you hit something with the axle tube or high-centered on the pumpkin you may have bent the tube. But then again I would also think that if it were bent enough to wear tires like that then the axle would be making some god awful noise going down the road at 70 mph. You sure it wasn't in for service recently and they may have rotated the tires without telling you? That would easily explain it.

 

Both tires wore on the out side edge? Pretty strange. I'd jack it up and see if anything is loose.

I could see one on the outside and one on the inside but I'd have to agree the axle could be bent.
