The aspect ratio (the 65 in your size description) does not correlate to the load range of the tire. I am surprised that a 1/2-ton truck would have Load Range E tires, I suspect someone put the wrong tires on it at some point... Look at the door placard or owners manual to confirm... I guess with the new tow ratings they are putting on 1/2-ton trucks they may run E tires to meet the ratings though...
I've put the tires on. The factory a/r is 60. I am saying because I went to a larger aspect ratio to get a taller tire(my preference), it jumped me to load range e because they don't make that brand in that size any other way.
