This is a discussion thread titled "275-70-16 tire pressure", within the Tires and Wheels forum, part of the Technical & Vehicle Assistance Forums category.
You all have been a lot of help before, so let me ask this question. For the few of you out there like me that decided to go with a 275-70-16 what tire pressure r u running. So far I have been running 35 lbs front and back and the wear looks even. I just had my Fabtech list and MT Classic II's put on with Revos around them. The ride is VERY stiff and I'm not so sure I like it yet. Looks great, but the ride is rough. Let me know 'bout the tire pressure,

I'm running 265/70/16s on my Tacoma. I run 30 lb in front and 28 in the rear.
So far that is what I've found gives me the best ride and tire wear.
If ya look inside the front side drivers door an the placard they have some their suggested tire pressure but its too low for my taste.
I am also running that size tire and I am using simillar tire psi as "Swift". I used the chalk line method to tell me what tire psi to use. Only I didn't use chalk. NTB set my tire pressure at a whopping 37psi all arround. The truck felt harsh to me so I looked at the tread wear, or lack of shinney new rubber. It didn't even go to the edge of the tire. So I let some pressure out and checked it again 5 miles later. I did this to all tires several times. It took two days to get all tires to a full contact/nice ride psi. Look in "MY Photos", at the pic showing both tires side by side. On the YOKO tire, you can see the dirt stopping at the edge of the tire, just like it should for even wear.
Thanks for asking this question and the responses. I'm running stock 265/70/16s BFG and been taking it to my dealer for servicing. They have the pressures set at 35lbs all around, and I was thinking it was a bit much.
Think I'll try the 30 / 28 as well.
Thanks again!

I just got a set of revos too and they put something like 34 pounds of air all around. Oh, yeah, it's stiff.
I bumped it down to 31.5 in the front and 30.5 in the rear. The ride is nice now. You can probably go between 30 to 32 in the front and 2 psi less in the rear (when empty) and you'll be happy.
You can definitely put less air in the rear than the front for "general travel" but be sure to pump up the rear tires again if you load up the back or tow something.
If you plan to travel at 80 to 90 a lot I'd bump the pressure up to 32 front and rear. Any more and it will be too stiff.
I drive 75-85 mph all the time, no problem. I deliver custom cultured marble hot tubs and counter tops, some times two hours away, still no problem.
I don't think I'd consider that "long term continuous" unless you're doing it all day. Or right after you arrive you're turning around right away and you're doing that pretty much daily.
I grabbed this from Firestone (I was actually looking for a chart though), but all the tire companies follow this rule of thumb concerning speed:
<<For continuous high speed driving, tire pressures should be increased by 3 to 5psi above the normal cold inflation recommended. However, for passenger tires, never exceed the maximum inflation pressure molded on the sidewall. The inflation pressure for light truck tires may exceed that molded on the tire by 10psi. Any recommended front to rear pressure differential should be maintained.>>
It's a linear relationship (kind of). If you drive 70 you'd increase it 1 psi, 80 2 psi, 90 3 psi, 100 4 psi, etc. Up to the max pressure of the tire.
Those are just "for instance" numbers but most of the manufactures will have speed vs air pressure charts that they can supply if they aren't on their web sites even.
If I follow the manufacturer (Toyota) reccomended pressure on the Seq. it squats terribly in the rear (17" Dunlops). If I up the pressure to 38psi (still way below Dunlop's max) I lose the squat and I honestly have noticed no change in ride. Thus I run 32psi front and 38 rear.
My '98 Sub always had a variance between front and rear from GM's own advice as they recognized the rear on these SUV's is heavier and can be loaded even more. Toyota, I believe says the same PSI all around and that is just not good advice, at least on these Dunlops with squirmy side walls.

I also have Bridgestone Revo Dueler ATs and when I came home from the shop
they had them maxed out at 44psi. I reduced them to 35 each and am thinking of gong down to 32 front and 30 in the rear to see if that little bit of reduction would smooth it up a bit.

When I first checked the tire pressures on my truck they were 36 psi all around. Way beyond the 26/28 in the door sticker. I lowered it to 30 psi all around and the ride imprived, but think I might want a couple more pounds in the front.

I've noticed that if I bump the pressure down that the ride confort increases a lot. So does the tracking and the traction. There is quite a bit of difference in the tracking even between 29.5 and 32 psi.
The downside is that the gas mileage suffers a bit. I think my rugged trails had less rolling resistance than my new revos.
But boy, these revos sure are smooth at high speed though.
I appreciate all the help guys. Like a lot of you, I had my tires set from the shop at 40 PSI. I dropped it down to 35 PSI and It seems to ride well. I realize the recommend PSI is in the door jam, but since I don't run a recommended tire size, I assume those pressures to be inaccurate. I may run the front at 35 PSI and the back at 33. Remember, it's a 275 70 16 tire.

Actually, given the same weight vehicle you'd probably need to run less air with the larger tire over a smaller one with the same design. That is if you want to get the same (hopefully even) wear pattern on the tires.
