Not to beat a dead horse her e but I do agree sidewall stiffness makes a difference.
I am running the Toyo MT's 35 x 12.5 x 18 tires at 80psi when loaded up and around 65 around town so I don't get beat up.
I think they have an "F" load rating.
Unfortunately no warranty comes with these tires and at about 5 bills each that sucks.
I have a little over 20k miles on them and the trad depth started off at 21/32" and I measured a couple of days ago and their averaging about 10/32" so their probably 2/3 gone at this point.
Im guessing I will be replacing in about a year or so with only about 30k miles on them.
For my piece of mind I'm ok with that trade off.
