What PSI do you run?

[mblouir]

Title says it all. What are you running?


I have 33x12.5R20 Toyo M/Ts and am still adjusting the pressure trying to strike a good balance. Generally I keep the pressure high (within reason) to lengthen the life of the tires and increase economy. I don't notice any increase in ride stiffness so it doesn't bother me. I check it every few thousand miles to see how it's wearing.

Right now I'm testing out 50 psi up front and 45 psi in the rear.

On the GMC I'm running 55 front and 65 in the rear, with 225/75R16 load range E

On the g/f's Dakota, with 235/75R15's we're running 35 front and anywhere from 35-42 rear, depending on how much load I stuff in the back.

I run 35psi in both the truck and car.

275/45/20 I run them at 37psi.

 

[Nick The Great]

I try to put mine at about 38psi. But with the warmer weather, I noticed they're right at about 40psi now.

I run 285/75/16 E rated Revos. I used to run them,unloaded, around 42 front 35 back. I noticed that the tires were starting to cup on the fronts. This was probably due to an oversized tire and not enough pressure. I increased it back to the manufacture specs(80psi) and they have started to run good again. Driving a HD, you try to get as much softness for a ride as you can.
