Good job of getting the "Real Weights" Too often folk simply drive on a scale and divide by 4. In your case you would have thought you had 3009# on each tire. Instead you know that you are off by 7.4%. You didn't say what size tires you have on the trailer but with a tandem axle I recommend you run no more than 90% of the published "Dual" load and to always run the pressure shown on the tire sidewall. If you have ST type tires you need to consider 65 MPH like the Red Line on your engine. It's possible to run at or even above the red line but not for long and you can expect much shorter engine (or tire) life.
We're running Goodyear 614 and I have been keeping them at 105 PSI, I will take your recommendation and take them up to 110. We run 60-65 mph to save fuel. We have about 12,000 miles on the this rig, and this summer we had the MOR/ryde IS and disk brakes installed.
Per Good Year tech support. Usethe tire inflation chart using the heaviest tire andthen go th the next psi on the chart.
Your heaviest tire is 3,185# so the chart says 3,300# at 90 PSI. The next higher is 3,414# at 95 PSI.
So per GY uou should be running 95 PSI. They said when you have more air pressure than needed you will have a smaller contact patch that = less stopping power and center of tire wear.
Don't believe me contact GY tech support!
I have ran two sets of the same exact tire as you 5 years each using the charts, not even a flat! One set on this Mobile suites running at 100PSI and one set on 32.5 Avion Platinum that I changed from E to G tires and ran 85 PSI.
Now I have changed the G to H tires on the MS with 100PSI.
