Goodyear Wrangler ATs worn out early?

My '17 TRDOR has 17,700 miles and I just had the tire rotation done at the dealer. They indicated that the tread is now at 5/32 F and 6/32 R. This seems like excessive wear on OE tires. Goodyear says they are 60K mile tires. What are your thoughts?

Thanks!

 

My thought is that Goodyear doesn't know how to make tires. Good luck trying to get Goodyear to prorate them, if they even come with a warranty.

 

That does seem a bit low. Mine are all roughly 7/32 at just over 21k miles. I don't think you'd see any warranty on them though, their website says no warranty on stock tires (that is, installed on a vehicle for wholesale) - at least here in Canada.
