How do I calculate tire pressure - axle weights?

[Concord1]

Is there a chart on line that I can use to calculate tire pressures for my Michelin tires on the motorhome. We don’t have a four wheel scale here, but was able to get both axels weighed.

Thank you! Ron.

Here's the formulas:

Front axle weight/2 X 1.05 = Weight to look up in single wheel chart. Add 5 psi for your final inflation pressure.

Rear axle weight/2 x1.05 = Weight to look up in dual wheel chart. Add 5 psi for final pressure.

The 1.05 is used to estimate side to side weight differences that you will see when you do individual wheel weights.

And finally, do not inflate a tire less that 80% of the max side wall pressure.
