285/70r17 C load PSI?

[mjg514]

hey 4gen crew,

for those of you with 285/70r17 in a "C" load, what PSI are you running for ON-road driving?

 

[who done it]

34 Front / 32 Rear.

Truck roadtrips quite a bit, found that to be the best for MPG / Ride comfort.

Do a chalk test, only way to find the exact sweet spot. Takes 5 minutes and a piece of chalk.

i'll def do the chalk test! good call there. totally acknowledge that the "correct" pressure can vary depending on weight carried in the vehicle, tire load rating, etc but was just curious if anyone out there running a similar 33 "c" load tire could comment on what they are running.

I'm running 285/70/17 Falken Wildpeaks (Load C) on 7.5 in wide rims (2012 Trail Edition 4Runner/FJ wheels) and running about 35 psi all around. Fair bit of weight on-board all the time with drawers, rtt, winch, V8, etc.
