When I had my 08 dually bought new and sold with 285k+ miles there was always a little wear on the outside tires up front but not bad. My 16 is looking the same way. There is no pull or wander at all.
I thought I read somewhere that it's normal because of the duals (4 tires) pushing forward in turns.
Maybe I'll have to take it in and have it check in the future if it looks abnormal?

 

mine feathered a little but I got about 38K out of them.


Still running the rears.


Took mine to my local heavy truck shop for a proper alignment.
