can yall tell me what psi ur running on BFG KO size 285/70/R17. my truck recommends 35 psi. but that seems too low. i was thinking around 44 psi.

 

My friend that has worked in a tire shop for 4 years told me AT/truck tires always last longer if they are kept between 40 and 45 PSI.

 

Mudd, your truck recommended 35psi for the stock "P" passenger tires. You no longer have Stock tires. If I remember, BFG A/T ko's are a "LT" type, Load D rated, 65psi max tire. You should be running them anywhere from 40psi when empty, to 65psi when fully loaded down.

AWH ....

Most Passinger "P" type tires are normally 35psi max cold (a few sizes are higher)

Light Truck "LT" Type, Load C = 50psi max cold
Light Truck "LT" Type, Load D = 65psi max cold
Light Truck "LT" Type, Load E = 80psi max cold

The type of tire your "AT" tire is ... determines its max tire pressure. The tire type, load range, vehicle weight, and load would determine the minimum tire pressure per tire manufacturers recommendations.

 

Thanks Sag. I was giving information assuming Mudd1 had standard LT tires rated "C" under standard driving conditions...

I have the same Michelin's on my '97 F150 4x4 as you have on your truck. I keep mine at 45 psi unless I'm on the beach in Mexico.

 

sag...I have the BFG TA KO tires on my truck, they are an LT tire but they are load range C.

mudd...I run them at about 42psi. My truck is usually empty or carrying a very light load and that pressure gives a decent ride without being spongy feeling.

 

SAG, ur right. my tires are load D. i have 45 psi in them now, which sounds like i should be fine. thx for yalls responses
