OEM Goodyear tire pressure

Trotorx2 · January 9

The OEM 27560R20 Goodyear tires on this truck always look low. I try to keep them at the pressures shown on the door placard but every couple of months they lose 2-3 psi. 32 front and 35 rear seems low to me but I come from a history of 2500HD that were 70-80 psi. What do you guys run and do you have issues with the Goodyear's slowly loosing pressure? The tire says max 51 psi. I love the ride but these tires sure look low all the time.

Tire load label in the door jamb. That is what you follow.

Temperature accounts for a large majority of PSI swing. Every 10 degrees F can lose or gain 1 psi.

41 PSI front and rear. Mine are Goodyear Dura Tracs on a Trail Boss. I usually run the manufacturers spec on the door placard. Mine do not lose any pressure excepting hot/cold pressure change. However it is not unusual to have slow leaks between the wheel and tire. My Harley tires leak a little and it drives me crazy. I will have to dismount them and clean the wheels in the bead area.

Others run higher or lower pressures depending on traction needs or ride preference.

I've never had tires lose pressure like these, not this fast. I've owned this truck since last week of Aug 2023 and this is the 4th time I've had to add air.

Bead leaks.

This could be the issue. None of the tires on the 2500's I've owned did this. I've never been a fan of Goodyear's, I usually get rid of them shortly after I get the trucks.
