Towing with E rated tires, that DON'T go to 80psi

I'm looking to get different tires soon and while I have been happy with my Hankooks (I'm on my 3rd set, albeit I only get about 25k out of them), I want to go a little bigger, and it seems all the E rated tires that have an 80psi max do not have the larger sizes.

My question is to those of you who tow with a larger tire that while being E rated, only has a max pressure of 65 (typically what I'm finding in the larger ones). I know the load rating is there in the specs, but I worry about them not being as solid as a true E, 80psi, one. Are they solid? Do you get any more sway (I, have an 8500# bumper pull), or are they "squishier"?

thanks for your input

ps, I wanna stick with 17"s since the wife will kill me if I start talking new rims

    This may not be the answer you are looking for, but due to the rating of my 265/75-16E's (3,415#) I only run them at about 65 to 70 psi when towing, as I only have about 5,550# of weight on the rear axle when towing my 5er, tires look fine and feel solid.

    Sorry, My bad, That is the only size Nitto makes that uses 80psi. The other sizes use 65psi

    There ARE tires out there that are E rated (have the load capacity), but only go to 65psi, for example:

    Duratrac in 325/65/18, E, 65 psi, 3860 lbs
    Terra Grappler G2 in 305/70/17, E, 65 psi, 3195 lbs
    Firestone Destination AT in 315/70/17, E, 65 psi, 3195 lbs
    Firestone Destination MT (same)

    My main concern is the squishiness; HOW WELL DO THEY TOW?

    thanks

    Thanks, but I'm looking for info from folks who have tires with max LESS than 80 (typically 65 for an E rated one)

    I put a set of Nitto Terra Grapplers on my Ram 2500, They have a load index of 126 which equates to a load range of 3750lbs at 80 psi (as opposed to the load index of 121 on most E rated tires). I was very happy with the towing performance, and they are made in the USA. I had to go to the 285 size though.
