Tire pressures, 5psi less in the rear

[Randy2400h]

I’ve been playing with tire pressures on my truck. I’m running Falken WildPeak A/T3W tires in a 275/65-18. So far I’ve found that running less in the rear doesn’t seem to effect my gas mileage but it does have a significant impact on smoothing out the rear end.

Right now I’m running 38psi front, 33 psi rear. I carry a portable pump with me if I were in a bind and needed to haul an unexpected heavy load. But for daily driving I simply don’t need the matching tire pressure in the rear, it’s overkill.

Nice, I'm curious now. Maybe i'll try that for a week of work commuting each way and test this myself.

I feel the same way. I have factory Bridgestones and there was a noticeable hop in the rear end in normal driving at 35 PSI ..as the sticker recommends....so I tried dropping the rears only to 33, and it made a noticeable difference in ride without any handling/mileage compromises. When I tow, I bump the rears back up.
