Odd tire wear question...rear passenger tire badly worn compared to others

[Brewcity]

Hey guys...just got my Tahoe today (FINALLY!!) and the passenger rear tire is badly worn on the outside of the tire. The front driver tire is also pretty badly worn on the outside as well...but not as bad as the rear passenger one.
Any idea what is causing this type of uneven wear? I want to fix the issue before putting new ones on.
Thanks SO much for the help with this.

are you sure it was worn on the passenger rear and not rotated from the front end? if it was on the passenger rear sounds like your rear end/axle tube is bent but i would assume you would notice if it was that bad.

probably just needs a front end alignment or some worn parts replaced if it did come off the front end.

Ahhhh...good point. I didnt think of the tire rotation. I really hope thats what it was...I dont notice any sign of the axle being bent.
Thanks a lot. Your guys are great!

both tire may have been in front at the same time with a bad toe alignment.
