265/75/16 D's on a 92 reg. cab shortbed stock gears 35psi checkem if they look low. last trip 12 hrs 1 day best tank 23mpg's. i spent 2.5 years in a tire store max psi on side wall of tire is always cold and a 10 ply E load is always going to be harsh on a yota id air em way down 25 to 30 ish if you like ur teeth

lmafo i read that and said "wow, that guy does the same thing i do" and then i looked and saw it was me

haha, dont mean to change topic, but i literally lol'd.

but i air my 35x12.'5s up to 35 psi. do equal on road as i do off. and off-road i do just "surface mud" trails, so its perfect for me

if i ever know i'm gonna venture off trail, i'll just keep going till i start gettin bad traction, then i'll pull out my knife and airdown

Mine doesnt see any street, Im running bald 37x13.5 Xterrains at 5 psi all around.

40psi all 4, MESA 31-10.5...got 80K out of first set, have 22K on second set with about 65% tread life remaining.

Federal Couragia mud terrain, 32 psi cold

I'm running 65 psi in my Guard Dogs because that's what the shop put in them when they were mounted, but I'm thinking 65 is a lot for such a light truck especially when it's unloaded-should I run 45-50 when I'm not hauling?

Yea 65 is a lot, that is around what the 3/4 ton trucks run. I have always ran right around 35-40 psi on the street and found that was a good medium where you get decent wear, mpg's and not such a harsh ride that you have rattles from every spot in the cab.

Whom else is running Micky Thompson baja claws ttc ?
I'm running around 22-25 psi cold on the street.
Wondering what' everyone may be running .

315/75R16 Toyo MT, sidewall calls for 80psi, running 40psi. Still to much, gonna drop to 30.

Wow, a lot of people in this thread that have no idea. Airing up the tire too much causes the contact patch to be in the middle of the tire. Not only does this cause premature wear, it is also dangerous. Since you have less rubber on the road your stopping distance, and wet weather performance is greatly diminished. The best rule of thumb is to start at the door jam pressures, and adjust slightly for performance, and ride quality.

Many tricks for checking the contact patch. NEVER NEVER run the max PSI that is printed on the sidewall. This is the max cold pressure for maintaining maximum load capacity of the tire, and that rating will be much more than any of the Yota's here are rated for.

ALSO, anyone running more than 45 pounds on a standard valve stem is asking for trouble. Standard valve stems are only rated for 45-50 PSI, larger 3/4 and 1 ton trucks with E load range tires run high pressure, and they have brass high pressure snap in valve stems. Without a high pressure valve stem, the stem can actually blow out of the tire. This usually happens on the interstate due to high temps and pressure increases due to the temp increase. At highway speeds, rapid pressure loss almost always causes the tire to have a cap separation as the side wall disintegrates. This rubber flapping around will usually tear the hell out of the truck, including ripping fenders and door sheet metal right off(Best Case). Or it can cause a serious accident (Worst Case).

Anyone remember the big Firestone Recall and Ford Explorer Recall? The roll over accidents were due to ford using too low a tire pressure than Firestone recommended for that tire. When the vehicles were loaded down and on the interstate the tire sidewall would fail. At the time Ford had a door jam pressure of around 24 psi.

The reason you get better gas mileage on higher pressure is due to less rolling resistance since only the center of the tire is in contact with the road. I would never run more than 35 psi or less than 27 on the street.

i have 33 mud terrains running 35 psi

93Xtra-Cab

I run 45 psi in my 32s. They call for 50 psi.

SunshineMcB

I keep my 31" BFG ATs at 50psi. Ride feels better, easier handling (no power steering).

35psi for life!

23psi to have a almost full width contact patch in 33x10.5 BFG ATs
How the hell are some of you driving with over 35psi? Your contact patch must be about an inch wide on the road not to mention how ruff it must be.

mt4runner99

I run 40psi for the highway. If i'm doing any prolonged offroading I go down to 20psi.

ericwudi0830

45 psi no matter what

Just bought BFG A/T K02 265/75-16 and was installed @35#. Stock size was 265/70-16. I was not aware that the tires installed were E rated.
These were way to rough in city driving, The door said 29# front and 26# rear for stock size. The tire shop recommended 32#F and 29# rear.
This was a little better but still stiff ride, I believe it may be due to the E rating. I'll pay more attention to the load rating in the future.
