32" bfg ko2 psi?

i am running 32" bfg ko2 they are e-load i am running 32 psi in them what is everyone else running is this not enough this was the recommend from dealer.

 

Out here in AZ on the street in the winter I run 45ish. In the summer I go between 35-40 depending on how hot it is.

Edit: summer I inflate to 35-40 because the heat will expand making it go to 45

 

i run mine at 35psi. anything 40^ seems to give it a really rough ride.

 

What size, exactly?

 

PSI "required" will vary with rim width, truck weight, cargo weight, AND tire size. First, you need to establish a good contact patch....No arbitrary inflation number. If you had a 3/4-ton pickup that routinely hauled a couple thousand pounds in the bed, you might want 60 or 70 psi....(or more) A Tacoma that runs around empty most of the time, 30PSI might be enough.

I'm running Duratracs....I've heard tire pressures mentioned from 28 to 60. After a little experimenting, I'm good @ 34psi. Wear is minimal, the entire width of the tire is in contact with the road, the ride is great, gas mileage is as good as a Tacoma will get, and it hauls an average load safely.

Bottom line, these trucks don't need tires blown up to 50 or 60 psi. Tire manufacturers will have a max inflation number for maximum hauling capacity, but that's not a realistic number with a lightweight truck in normal driving conditions....

Run the pressure too low, tires heat up and INCREASE psi. There's a sweet spot somewhere in the middle. (Usually in the 32 to 36 psi range) If driving causes pressure to raise more than 4 or 5 psi, you're starting off too soft....

 

Thanks all for opinions I am pretty sure I am running 285 75 17s maybe 275 not sure without looking they were on truck when I bought it

 

Chalk test.

 

I have done that for my race car I run scca but mostly to see how much camber I need to run etc... not so much on psi

 

Many people use chalk testing for psi. Google it or even YouTube it. Tire PSI varies from truck to truck, there's no right answer.

 

I used this document to calculate based on those variables mentioned.

This will get you the equivalent of GVWR PSI of the OE tire.
I haven't done the calculation, but based on your size, I'd estimate around 33 PSI.
