Air Pressure

What is the correct amount of air pressure to run in my 05 Ruby Unlimited.
I have added about 200 pounds with winch, tuffy security drawer skid pan etc.

Thanks

As much as you're comfortable with while still getting a good wear pattern. I'd guess between 26 and 32. It's very subjective though.

I run 35 on the road but that's just me. With the 10" wheels I'm getting even tire wear and it feels peppier/better handling at the higher pressure.

I run about 26 lbs for the last 8 months. Feels real bouncy when I put them at 32lbs.
Good luck

I run mine at about 18lbs, I had them around 30ish, and dropped them a week ago before a trail ride. Made it ALOT smoother on the street.

The best way to find out is to chalk test it. Take sidewalk chalk and color up your tread from side to side. Drive a little ways strait in a parking lot and make sure you have contact from the edges.

do this if you really want to know what to run,
remember though

to much air=center wear
to little air=outer shoulder wear

the less air you run the smoother your ride also.

And the less air you run, the lower your gas mileage. Mine drops like a rock when I get down below about 28 psi.
