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.

Can be run at lower inflation with reduced load rating or run at max pressure to have max rating.
I would run 75-80 unless there was a handling issue.

Many people say run them at max sidewall pressure. But manufacturers post load vs pressure charts for a reason.

I want my TT tires at maximum load bearing pressure.

Don't forget, your valve stems may not be rated for 80 psi.

Download the tire inflation chart for your new tires.
Weigh your rig equipped for the road.
Use tire pressure from inflation chart. I go 5 pounds over for a safety factor.
