I think I might have not made myself clear? You are all telling me what I already KNOW (and way more than I asked).
I was simply looking for anyone who is towing with an E rated tire that only has a max of 65, and how it does towing the typical weights we tow.
That's all.
Just wondering how it tows.
That's all.
I fully understand what you are asking and why.
I tow heavy with my modified Excursion, we pull a 41' 11k TT with a tongue weight of 1450lbs and can see up to 6000lbs on the rear axle fully loaded, but usually a little less than that.
We had Goodyear Silent Armors in 265/75R16E (3415lbs @ 80 PSI) these factory stock sized tires performed very well for us running them at 80 PSI when loaded. I upgraded to 18" OEM rims and went to a set of Nitto Dura Grapplers in 305/70R18E (3750lbs @ 65 PSI) running at 65 PSI loaded. The performance under load from the new 65 PSI tires is every bit as good as the stockers, they feel as solid as could be with ZERO squishiness or squirm. I am extremely happy with these tires, they perform great, are the quietest truck tire I've ever run and they seem to be wearing very well. The larger lower pressure tires do not run any hotter than the high pressure tires, we use a TST 507RV TPMS system that reads both tire pressure and temperature. If anything the larger tires may actually run a few degrees cooler, but that is a tough call to be exact on as there are too many variable but it is safe to say that they don't run hotter as earlier stated. As long as your rims are wide enough for the larger lower pressure tires (I went from stock 7" wide rims to 8" wide 18"s) then you should be fine and may even gain a little tire load capacity like I did (+670lbs per axle).
