Tire Pressure Your Running on Standard 16" Tires?

[BamaDrewski]

I purchased some Michelin LTX AT2's a year or so back at Costco when they had the $70 off sale. The specs on my 2000 T4R 4WD LTD say to run the tires at 32PSI. Costco puts nitrogen in the tires. I have started running my tires at 36PSI as it seems to ride better and my mileage is definitely better. (I track and record every tank)

I have the standard 265/70-16's on my rig. For those running standard size 16" tires, what pressures are you running in yours?

35psi

35psi

This.

 

[I_bRAD]

35psi front, 32 rear (when empty)

Running 265/75

34 all around works pretty good for me ln most cases, but 30 makes for a much softer ride.

 

[JayRolla]

Always ran what was on the door if stock size and load.

 

[jfraser73]

I'm running 35psi also.

 

[he's gone]

usually 34 in the front and 32 in the back. If i have a load in the back or am trailering i will run them up to 34-35

I have found that running even just a little more air will cause uneven wear on the center of the tire.

Exactly!! I have had some major wear issues on muds with over inflation. I have found softer always wears better. I run my 33" muds at 28psi front and 26psi rear.

I have Cooper AT3 (265/75), load range C, and run them at 40 psi. At 32-35 I lose about 2 MPG.

Same boat. Run between 38 and 40 all around. Haven't done a chalk test....that's because sometimes I get lazy:bowl:

at 40 PSI your tire circumference is probably a few inches longer, no wonder you're getting better mileage.

you might be going a couple of miles an hour faster than the odometer too.

I ran my Yoko Geolander AT/S's (265/75r16) around 32-40 depending on the time of year and all of that. At a load-range E, they were a bit...harsh. My gas mileage was great though, and they still have decent tread after 40k miles. I just bought a set of Duratracs though because my winter traction started to suck last winter.

I'm going to keep the Duratracs inflated to the high 30s if not 40, and hopefully they'll be a nicer ride because they're LR C instead of E. I'm curious, why do people have lower PSI in their rear tires? I always thought the opposite was recommended.

When I had stock size tires I ran 32-35 PSI.

Now with my 255/75/17 C Load tires I run 39 PSI all around. Seem to be wearing pretty well so far.

He's running 40 PSI in C load range tires. That's pretty normal as they take more pressure.

The lower pressure in the rear is presumably because the front of the truck carries more weight with the motor, transmission, t-case, and front diff all being up there.

Ohhhh, that makes sense. I just checked the receipt and they aired me up 35 up front and 40 in back. However, I have my four old tires in back, so...I guess that counts for some weight!

I'll probably air up my fronts to 40 then and air down my rears to 37 or so because I tend not to have a lot of weight in the rear all the time (read: junk in the trunk).

I've never really worried about running different pressures front and rear. I think the 2nd Gen Taco calls for different pressures front and rear from the factory but I doubt many owners or shops follow it.

Actually most shops do follow it. All tire shops I know if on stock load and size tire they will run recommended pressure. My bronco, wifes Expedition both called for more front tire PSI. Tire shop I worked at followed recommended tire pressure from the door jam.

I stand corrected then. I just made an assumption. I know the firestone here doesn't touch my tire pressure ever, even when I had stock size tires and ran them at 35 PSI. They probably realize I'm a little more involved in my cars than most people though...

Well that only happens if they install new tires. I agree most shops wont touch tire pressure unless was told to.

i understand they can take more pressure, but that doesn't change the physics of the situation, does it?

I have two trailers with same tires, they can take 50 PSI, but on my BBQ smoker (1400#) I run a lower pressure than the trailer I load a 3000# tractor into. If I am running the big trailer at 45 PSI, with no load, it is obvious only the middle of the tire is touching the ground.
