Recommended Air Pressure for a Goodyear Endurance ST225/75R15 Radial Tire
Updated 06/15/2023 | Published 06/14/2023
Question:
I have a 2021 Imagine 2970RL by Grand Design with Goodyear Endurance ST225/75 R 15 - E with a cold load of 2470 and Max PSI 80. My trailer fully loadedmeaning GVW and Cargo is around 8,995 + 1300 lbs, cargo, what should my PSI be under normal highway conditions? If Im reading Goodyears Load/Inflation chart correctly, somewhere between 65 and 70 PSI ? Im trying to set the Low and Hi Pressure sensor on my TST and they recommend 10 setting on the low pressure alert and 20 on the High pressure alert, but is that based on the Max PSI of 80 on a cold tire or the recommended PSI, at 70 PSI - LO 63 and HI 84, do these settings seem reasonable?

Expert Reply:
70 PSI. The Goodyear Endurance ST225/75R15 Radial Tire item # LH33FR, you were looking at, is a load range E tire with a maximum capacity of 2,830lbs at 80 PSI per tire. The air pressure can be lowered to as much as 25 PSI which will support 1,430 lbs per tire or as high as 80 PSI with a 2,830 lbs per tire load. Those settings for your tire pressure sensors do sound correct.
I have included the tire pressure chart from Goodyear on the allowable tire pressures and load capability ratings.
