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 65.

Should I run 65, 80 or other PSI?

Visually the Load Range E look better at 80 PSI without a slight bulge.

:) Hi, I just did the same thing. I had Carlisle D rated ST tires on my trailer. At 80 lbs. it would most likely destroy my trailer. At 65 lbs. my E rated Goodyear Endurance tires have the same load rating as D rated tires do at the same pressure, 65 lbs. I set mine at 65 lbs. and the stiffer tire shook things loose that never happened before. I lowered them again, this time to 55 lbs. and all is well again.

Note: my trailer has a GVWR of 6,300 lbs. My pressure setting would most likely be too low for a heavier trailer.

According to the Goodyear Endurance inflation table, My size tire at 55 lbs. inflation = 2,270 lbs. each, X 4 = 9,080 lbs. That's more than enough for my trailer.
