Tire Pressure When NOT Hauling

Recommended tire pressure for my 2019 gas, short bed, crew cab is 60/75 PSI front/rear for 275/65-R18. I'm assume this is based on a fully loaded vehicle. At least 75% of the time we won't be hauling and be a daily driver. Has anyone experimented with lower pressures to smooth the ride out any?

Thanks
Craig

Our 2019 F350 (details below) t/p specs are 65F and 80R. Lightly loaded, I run ‘em at 55 / 65. The ride is greatly improved, and no TPMS warnings so far.

HTH,
Jim / crewzer

I just run mine at the door sticker's recommendation of 70/75, whether hauling or not. But then again, during camping season it probably sees 60% hauling time, 40% run-around driving, as I don't need to drive to get to work, and I don't want to mess around with constantly airing up/down the tires.

Been wondering about the TPMS issue myself. I've been meaning to air mine down to 55 all around to see how it does. No need for 75psi on the unloaded rear axle. First truck I've owned with these stupid sensors.

60F / 65R on mine.....run it towing and not towing.....rotate tires regularly and have no issues. I don't want to have to mess with the air pressure all the time so just run it at what the sticker says.

I air them up to the max, per the door sticker, or near it, at all times regardless. I don't notice it rides that much different. And with the valve stem slow leak, it gives me some buffer before I have to get air again. Going to get that addressed one day soon. It's only 2 tires doing it for now.

50 front 45 rear at operating temperature with Tires that have a 65psi max. There is a quick formula you can use to find the exact pressure you need depending on the inflation load index of your exact tire. You’d need to weight the front and rear of your truck to get it precise. Or do a chalk test as I did and determine the best pressure unloaded.
