the outside of the tires are worn more than the inside, could it just be from driving in the city and turning alot???? this was a plow truck btw, but the steering wheel is turned about 45 degrees to the left going straight down the road....

so could it just need ball joints up top and a alignment? i will know tomorrow when i get it up on a lift but i kinda wanna get a idea before i get under this thing.

its a 2001 2500 5.9 gasser if that helps

 

could be any of the steering parts. I would inspect everything just to be sure. I remember reading some where that bad control arm bushings will make tires ware on the outside.

 

Just being on the front axle all their lives will make them wear like that too. Rotate your tires.

But, check all the front suspension/steering parts as well.
