Another tire question? Real quick though.
I just recently got new tires on my truck and they are 285-75-16 rated D. Had the rated E on there and ran them when towing at 75 psi, 80 was the max. Now my question is i got a D rated tire with a max tire pressure of 65 psi. I,m going to be towing my TT rated 13,000 dry weight- 15,000 fully loaded. Do i run them at 65 highest pressure or do i run them at 60 psi to give a little flex? I worry about the 8 ply having to much stress put on them when towing running at 65 psi.. What do you all think, 60 or 65? Thanks

The yokos that i got are rated D at 33005, the E rated where at 3415 =110 per tire difference. It,s a TT and the tongue weight cant be no more than 3 thousand pounds. I see lots of people on here hauling their toys and running d rated tires and wanted to bump up a size. I did make sure i got a d rated that handled at least 33 hundred pounds per tire.

Thanks fellas, i normally go with spec,s that are for our trucks but wanted a little bigger tire. I know there,s a reason why they don't make a 285 E rated or above for some reason, somebody told me awile back. Rick, you have me alittle concerned, tell me more!

Run them 65. In most cases you will find a 285/75 load range D actually has more capacity than a smaller load range E. I think BFG and maybe Toyo make a 285 E now but not certain.

My only concern is in the sidewalls. Thats where the biggest difference is between the E and D tires, now this is what a major tire store that does all tires, tractor, big trucks and passenger vehicles. With a load on the tires while going down bumpy roads, what gets hot and fails are the side walls. He said too much flex will heat the steel bands in the tire and could cause failure. I had to go to G rated tires on my trailer because of the loads I carry. I changed 8 tires on one trip to Arkansas, had 3 blow outs on one axle, so I put G rated tires on the one axle. I still have the E tires on the rear axle. I never had a flat on the rear axle. The front must be taking extra weight.
Another thing he told me was make sure you have the right amount air in the tires. I asked him what the proper psi to keep in them and he told me to look on the tire. That is what that tire is supose to have it it. I keep 80 psi in the E and 109 psi in the G. I have not had a flat sense that day.
I don't know that much about tires, but I do listen to people that do.

Safety is my number one priority and my main concern was the side walls of an 8 ply tire. What i forgot to mention is when i bought this travel trailer i also got a weight distribution hitch, the whole system. My question is that most of my weight thats spread out because of the distribution hitch, i,m only dealing with the tongue weight which is about 3000 to 3500 pounds. The rest of the load is pulling. Just trying to figure everything out before embarking on a possible nightmare of a trip from tire failure and kicking myself in the a..Then hearing the wife,s take on this, ouch...
