Tire Pressure

[Newtwo6x6]

Great, thanks to all for the info. I will try 3.5 or 4 psi. see how the ride is. And yes, it was very hard on the back. 20 psi was what was in the tires when I bought it, 2 weeks ago. Guess I have a lot to learn. And with all the information here and the 6x6 world forum, should be a big help.

yeah nitrogen, and when i said oxygen, i meant just plain ol regular air compressor air!

Over here NOS is nitrous oxide, not nitrogen, that's why it surprised me. NOS goes with a big bang, it also makes cars go very quickly
And you know the downside to oxygen obviously (even at ambient pressure) as you said it was just air no oxygen.

There is a very good reason for using nitrogen, besides holding pressure and being more stable, as there's no oxygen in it (theoretically) it inhibits corrosion (stops your wheels rusting from the inside)

We use it in pcp air rifles for the reason you do (stability) and for the lack of corrosion.

In my at 189 25/12x9 I run 1 to 2 psi in the summer that would probably mean 0 psi when its cold mornings and 5ish psi in the sun.NCT

Lower tire pressure gives the tire a wider footprint and softens the ride.
I run 3 to 5 psi

I believe tire presure to be very important,especially to someone new to AATVS. Steering can be greatly improved on both 6x6 and 8x8 if there is more tire presure in the center tire, or two center tires on an 8x8.Tire size and tire presure can go hand in hand having the biggest tire in the center,and also more presure,which will make the unit pivot in the center,not on the ends, especially with older units that don't have the front and rear axles elevated.
Also, as a general rule(of mine) the harder the surface that I run, the softer the tire, and visa versa. The great thing about messing around with tire presure is:
#1, it's free to do.
#2. anybody can mess around with it.
#3 you can custom fit the presure to your own unit as long as you stay within presure limits.
#4 it will greatly improve the ride,turning and overall enjoyment of the unit.
If you are fighting the steering,this is a great place to start,you might be very suprised at the new preformance..... for free.
