PSI when using higher load range tires.
My trailer had 4, D load range tires. From advice of many friends I've up graded to E load range. Just got a set of Good Year Endurance with max PSI of 80. Previous tires and trailer sticker says PSI ...

Thanks for all the replies. I've been busy working and just drove from Nebraska to Maryland with my truck and travel trailer with 10,000 to 11,000 pounds loaded.
I decided to run 70 PSI cold and the ride seems better than at 65 PSI cold.
I did some research based on all the comments.
My wondering about PSI was sparked by the tire installer putting 80 PSI in the 3rd set of Goodyear Endurance E load range tires I've put on my trailer.
Without research I would have just deflated to 65 PSI cold like I've done with every tire I've had on the trailer since 2014. I learned sometime in my late 20's that my grandfather taught me wrong to air tires to PSI on tires. We air to the spec written on the door of auto... So that's what I've done with trailer but since I upgraded load range I wondered.
I found my rims could handle 80 PSI if needed.
The valve stem I could not figure out PSI but there likely good to 80 PSI. Every Valve Stem spec chart I read showed if stem could handle 65, it could also handle 80.
So... based on what Goodyear specs are, my likely weight and a few other things I've tried 70. For my next jump I'll try 65 and see if I feel the difference.
Thanks again for replies and hopefully this follow up post won't spark more debate :)
