|ESP||Please tell us your not running up to 10 pounds over the cold psi max rating?|

Exception--hills/shale/loose dirt--then 4lo and 15/18 psi !!
If you're on washboard roads and you're going a good distance--then airdown-
Otherwise, especially in good weather, don't even worry aboutit !!

|bbrown626||What do you run for pressure on mild trails?|
|05-26-2011 02:05 PM|
On the jeep 32-11.50/15 I run 32 lb all the time .
My 1/2 ton 4X4 pickup 5 # over or 40 lb .
To date I have had zero problems get very good milage from the tires and gas .

I do agree with tread wear and traction. and always take the mythbusters with a grain of salt...
Control, 35psi (manufacturer recomendation)
tyres at 10psi = 3.7% increase in consumption
tyres at 30psi = 1.2% increase in consumption
tyres at 40psi = 6.2% decrease in consumption
tyres at 60psi = 7.6% decrease in consumption
Results not in video...

|JYJeep||search and read "chalk test" basically run a chalk line across the tire, when the jeep is loaded to normal condition conduct test starting at max pres listed on tire/door. Drop pressure to the point that chalk wears off evenly across the entire tread. Then add 5 psi for street handling.|

|Sherpa||I run my 31" MT/Rs (first gen) at 25 psi on the street all year round. Depending on the terrain, I often don't air down when 'wheeling since I don't have an onboard air source. When I do air down, I typically only drop to 18-20 psi (again because I don't have onboard air).|

I'll stick with my method.
I have 60 k miles on a set of cheapo AT tires on my truck. No uneven wear at all and I averaged +1-3 mpgs since I have run them over pressured. Never had any traction issues on the street. I also rotate every 4k miles.
I also have 40k on a set of all seasons on my wrx wagon. Same thing. Better MPG, and great wear. 4500 mile rotoation on those. Also never traction issues. In fact, My wife went to work this winter with a level 1 snow emergency.
I've done it both ways on several vehicles and always come to the same conclusion.

I run mine at 28/30 psi-works for me !!

[QUOTE=95YamJam;1260896]I usually run street tires over the rated pressure by 5-10 psi. Beter MPG, and the tires run cooler. Bit bumpier ride but...
Uneven tread wear, less traction (especially in rain or on ice), horrible ride.
Air them correctly, the MPG benefit is a myth.

This article is great for offroad airing down but they are very vauge for the onroad part.

|daggo66||I run mine at 37. I go by the door sticker. Actually I go by the door sticker of a Rubicon since I have an X and I'm running Rubicon tires and wheels.|

tire pressure on road
after reading this article; Under Pressure: Proper Tire Pressure for the Trail - Jp Magazine
got me thinking for you DD do you have the pressure at 35, 30, 25 or lower?
what are the benefits
