PSI in BFG A/T KO 285/75/16?? NEED HELP ASAP!

Hey guys, just got my tires on and need to know what PSI to run in them!

Need answer ASAP, thank you very much TW!

 

The only way to know for sure is do a chalk test, but for reference I run my nitto trails at 36 in the front and 32 in the rear.
When loading the bed up or pulling trailers I fill the rears up a bit more.

 

Somewhere between 32 - 40 psi for on-road driving is fine.

 

Thanks guys, will go try this.

 

Chalk test is good idea, but for now, I'd say 36 rear - 38 front...that's what I run in my 265's

 

Thanks, aired down to 38 PSI all around, hopefully the annoying light will go off now. If not, drop it down to 36. haha

 

I use water to test tire contact. run a line across driveway about a foot wide and drive thru it, should see tread pattern. keep airing down to get full contact. I am guessing around 32 psi for front and 30 for rear with stiff sidewalls.

 

I thought tpms indicates low pressure? It shouldn't matter how high the pressure is. Did the shop mess up the sensor?

 

how would they have messed up the sensor? last time my light was on, I took it to the dealership and they said I didn't have enough air pressure in the tires, so i'm not sure?

 

What rating is the tire? C,D, hopefully not E.

 

They're E I believe..

 

Under the dash is the TPMS reset button. I believe you just hold that button for 3-5 seconds to reset the base pressure reading, but I could be wrong...I'm sure it's on here somewhere. I believe the light will come on when you are +/- 10lbs or more from base pressure.

Reset and see what happens...

 

FIFY?

 

Thanks man, tried that earlier and it did nothing

 

New rims? If not, maybe they damaged the sensor or just didn't pit them back on...
