Tire Pressure?

My truck, 2000 F-250 ext cab 4x4, calls for 65psi in the fronts and 80psi in the back, is that right? 80psi in the back seems very high. This is my first 3/4 ton so I just wanted to check for sure. Thanks

The higher rear pressure is for hauling loads. If you are running empty or using as a daily driver without hauling, run 65 psi front and rear. It will ride easier too.

Make sure you check the tire specs too and the max loaded PSI. I run 65 all the way around and then 75 in the rear when I'm towing. All of the reason for the high PSI is to create less rolling resistance.

What he said

An example is my tires are 295/70r18's with 4050lb capacity at 80psi. 75% of the time i'm empty (no load) so I run around 60psi in the rear, 65 in front (engine is heavier then the weight of the rear of the truck). Eases the jolts a bit - smoothes the ride. When towing like this weekend - i'll increase the pressure to 75psi (remember air expands with heat). After the trip back down to 60psi.

I dropped the pressure out back to 55psi and 65psi in the fronts, what a differance in the ride. I just bought the truck and the guy I got it from was running 85psi front and back, made for a really rough ride. Thanks guys.

85 in the front and back!? That's wild... Glad that you got it under control though
