What Tire Preesure U Guys Run?

[slimjim2525]

I have the truck below. It has the Bridgestone dueler AT's. I got a message from onstar via e-mail that my tire pressure was low at 30psi, in all 4 tires. Sure enough, I check the DIC and all tires are around 30 psi or so. So I look at the side wall it says max psi of 44. So I figured I would go 90% of max psi so I inflate to 40 psi all around. And man now I can feel every little crack in the road. It feels like shiiit. I'm gonna drop down to 35psi or so and see how that feels. Was just wondering if you guys have a formula for where you put your psi at, or what.

I use what the door sticker says. 35 PSI all around.

Crap, I forgot about the door sticker. you guys will have to forgive me, I'm trying to recover from two broken legs, and I forgot to look at the door sticker, and I am not looking through the DIC much lately either. Sorry. If I had been cruising through the DIC, I would not have gotten the message from onstar via e-mail.

We actually had a talk about this a while back. I run 28 lbs in the back and 35 lbs in the front. If I load the bed up, I go back up to 35. Since I started running 28 in the back the ride has been smoother and hitting bumps has been much more predictable. The rear end doesn't bounce around as much. I'll see if I can find the thread about it...musta been a year ago or so..

Do not use the DIC to set tire pressure use a digital guage so you are getting consistent pressure with one guage not 4 different ones. Never use the MAX on the sidewall its just a max psi. Always use the door sticker for your vehicle tire pressure starting point.

Heard on the radio to use Nitrogen instead of air. At first I was like WTF, is this another blinker fluid joke. Since Google is my friend I did a quick lookup and sure enough some people do put Nitrogen in their tires, guess it helps with the bumps.

 

Still going to stick with regular air since it is free.

 

I keep all 4 tires between 34-36psi

Nitrogen doesnt fluxuate when the temperature changes.

There is Nitrogen in the air we breath and going to 100% would require you to go and have some Nitrogen added every time your tires got low. Not worth it as far as i am concerned.

I was using a pressure gauge to see the accuracy of the DIC, and it was dead on.

In EVERY car or truck I have ever owned I run 3psi over what it states on the door sticker. I even got 46K out of the crappy General Ameratrac tires that came on my silverado.

I keep mine around 36/37 psi.

I use a round dial type air pressure gauge (The one I have is from Snap-On) There a lot more accurate than a digital or "pencil" type gauge.

The atmosphere is 79% nitrogen, because you can not evacuate 100% of the air in a tire, about the best you can hope for with 3 inflation/deflation cycles is 95% nitrogen concentration. Consumer reports checked it out and determined that the main claim which is reduction of pressure loss, was helped by reducing the loss by a little over 1 psi over a one year period. At $5 a tire for the extra 20% concentration of nitrogen, I'll pass.

I've found you can run the rears significantly lower than the front when unloaded. It really improves the ride and traction. I have Toyo A/T's running 45/30psi. Just remember to air up before carrying a load.

I've got the 20's on my Denali and running about 36 all around gives the best ride, contrary to popular belief that more gives a worse ride. The door says 30.
