Title: Tire Pressure Calculator
Post by: Conundrum on April 16, 2015, 08:01:17 AM
I created this spreadsheet some time ago to help me calculate my tire pressures based off the article I linked to from the spreadsheet.

You basically input your Gross Vehicle Weight and Load and it'll suggest a pressure for the street based on the load capacity of the tires which you also have to know.

For off-road it requires you to measure the distance between the rim and ground and input that with the pressure of the tire during the measurement.
Let air out until it reaches the 75% of tire height suggestion and record that pressure amount. This is what you'll use for off-road to maintain maximum footprint.

Hope this helps!

Interesting, may need to play with this.

I haven't had the time to use it on the new tires. They are I think about 3100 lbs per tire with the load range E so I know they don't need near the amount of air I've been running. I took them down to 35 and I think most of the tread is now hitting the ground and not the center of the tire with the 45 psi that was put in by the installer.
