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

mikey

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

    Let's stay on track, please...

    I'm looking for more people who are towing with an E rated tire that only has a max of 65 (and preferably larger than a 295), and how it does towing the typical weights we tow.

    Thanks folks

    No the results will not be the same...

    D rated = 8ply
    E rated = 10ply

    The D rated tire will have a weaker carcass and sidewall which will directly affect handling.

    To say both tires will produce the same results is hogwash...

    Having used both....Your clueless.
    But we can agree to disagree

    Your comparing apples/oranges. A 65psi D-rated is not in the same category as a 65psi E-rated tire. OP is asking about E-rated.

    I understand what he is asking for....regardless the results will be the same.
    Some D rated tires have more capacity than some E rated tires.
    As I mentioned check out the TC forum as they get a new guy on occasion who asking about using any higher capacity D tire at 65 psi vs 80 psi tire.

    Now if he's not trying to carry heavy loads with no heavy trailer pushing him around then a 65 psi tire (65 psi or 80 psi) may work for him if his truck has the correct rim width.

    I've tried 65 psi D rated which were higher load capacity tires than OEM 80 psi E tires.
    They were dismal failures. The truck handle much worse than the OEM tires.

    HOWEVER... both trucks were carrying max RAWR loads. One had a tall heavy 11.5' truck camper and the other was a DRW one ton in commercial service carrying max RAWR loads with a 21k fully loaded GN stock trailer.

    IMO you can get education over on the truck camper forum on 65 psi vs 80 psi and carrying heavy loads. Check them out. Or ask a them a question.

    I'm sure the 1" sidewalls help ;)

    thanks for the report!


    33.5" diameter tire on 20" rim = 6.75" side wall. :p

    My factory tires were only 32.8" diameter so had even less side wall...

    I put a set of Yokohamma Geolanders on my 150, load rated E, and run them at about 70psi rear and 65 front. When they were new, they were pretty squirmy because of the deep all terrain tread ("hair brushing" is the technical jargon). They settled in after a 1000 miles or so and have been a great all around tire ever since. Coming up on 59,000 miles and they should get me to 60,000 + before winter when I plan on buying another set. The more wear they get, the harsher the ride unloaded. Stands to reason though, since the tread gets thinner and the compound gets harder. I've been very pleased with their performance overall. I tow at about 8000 lbs, 1100 lbs tongue, and 15,300 combined, so maxed out on numbers.
