100% agree with you here ... related question; are WHEEL loads evaluated by anyone other than their manufacturers? My older (2008) F-150 has OE wheels rated 2100 lb. Other OE fitments range from 1875 through 2100 (ignoring the 7 lug at 2400 used with their HDPP).

Ford is the only vehicle manufacturer I've seen publish OE wheel ratings, but have not looked a lot; I've seen lots of "will-fit" offerings that scare me ... are there standards?

You guys need to remember that these are 10 ply tires. Not your average passenger car tire.

They were not meant for a soft ride from the get-go.


Reliable source apparently sells tires ... because THIS is what happens when you grossly over inflate lightly loaded truck tires.
