what psi are you guys running?

 

Thats awesome to hear, and i will definitely be babying these things.

 

38 psi all around in a '79 Chevy K20 4x4 with 37X13.50R18LT Load Range D 8ply.

 

hmmm wonder what a good psi is for a 37-12.50 -20 im running 55 psi because the truck is over 8800 pounds load is E

 

On mine the max is 70 psi and I run 60 unless I am doing a bunch of towing at once. These are on toyo mt's as well

 

A lot depends on what kind of load you are hauling.

Unloaded, daily driving, I usually run about 65% of the max load psi. Towing and hauling stuff, I up it depending on the load.

Most of the time, with the trucks I have had, if I run over 65% max unloaded the ride was harsh and I would get more treadwear in the center, indicating over inflation. This is what has worked for me in the past.

Now if your daily driving includes towing a trailer or hauling I would go with 80% or more.

 

I did 50psi for my 33's

 

Im super pumped for this. Just got my PA body lift in the mail today, just waiting to order the rims and tires.

 

hahahaha on my thornbirds i had on my jeep i ran 12 psi, it was a straight offroad jeep though, better traction
