need opinions on tire pressures
We have a little 19 foot 2014 Bullet Premier I just put on a complete new set of the Goodyear Endurance 205/75R X 14 tires. They have a "D" load rating, putting their single max load single at just ov...

Answers to your question isn't a vote but comes from experienced trailer owners.
Always befuddled me why a new person comes on a website where folks have 20-30 years towing trailers and don't follow recommendations. Many of us have learned the hard way why it not wise to derate a tire on a trailer with a minimum pressure from a tire chart.Others and OP needs to spend some time on this tire engineer/expert Tireman9 rvtiresafety blog and research why the majority recommended max pressures vs a derated pressure in tires on a trailer. Truck or a motorized rv, with tires at the corners , pressure need don't apply here
Goodyear says on the tires side wall "inflate to 65 psi". No questions about what Goodyear recommends.
Goodyear also says;
Goodyear Tire and Rubber .... weighing RVs
Special Considerations
Unless trying to resolve poor ride quality problems with an RV trailer, it is recommended that trailer tires be inflated to the pressure indicated on the sidewall of the tire. Trailer tires experience significant lateral (side-to-side) loads due to vehicle sway from uneven roads or passing vehicles. Using the inflation pressure engraved on the sidewall will provide optimum load carrying capacity and minimize heat build-up.
Now if the new tires have too much pressure for the wheels or the new tires have more than 20-25 percent above reserve capacity above the axle ratings then I like this advise from another experienced website;

Tire Load and Inflation Ratings
Note: Towable – Travel Trailer/ 5th Wheel owners Due to the severe use conditions experienced by tires when axles are very close together – tire industry experts recommend maximum (sidewall) inflation pressure for towable tires unless this causes a sever over-inflation situation (20psi+), often referred to as the ‘basketball effect’. If this is your situation allow a 10 – 15psi safety margin above the minimum required inflation pressure.
