Understanding Air Pressure

[danford50]

I weigh my class c the steer axle weight is 4320, the drive axle weight is 7920 when I go to the michlin chart to see the proper weight it does not show my two weight how do I put the proper pressure when the chart does not show it, or a better question how do I read the chart. getting ready for a short trip for tomorrow

the Michelin chart is sub-divided by tire type/size.

first select your wheel diameter: 15", 16", 19.5" or 22.5".

then scroll the page to find your specific tire type and size: XZE, XRV, 265/70R19.5, 255/80R22.5, etc.

what type and size tires do you have?

Divide the axle weights you now have by the number of tires on that axle. Look that number up in the chart for your tire size and rating. If your weights are too low for the cart use the lowest pressure for your tire shown in the cart line. When all else fails use the placard weight shown in your unit.
