Tire Inflation

Recommended Posts

Welcome to any new FMCA members. If you have questions on tires you should check out the TIRE thread in the Technical area.

Until then here are the general recommendations

I do not see posts with actual side to side measured loads on each tire.
Single axle trailers should:

1. Confirm actual load on each tire
2. Calculate 115% of the heavier end
3. Check Load & inflation tables using the 115% number to learn the MINIMUM allowable inflation
4. Add 10% to that inflation number and use this new number for your goal Cold Inflation psi

Multi-axle trailers should:
1. Confirm actual loads for each tire
2. Calculate 115% of the heavier end
3. Check Load & inflation tables using the 115% number to learn the MINIMUM allowable inflation
4. Add 10% to that inflation number and use this new number for your goal Cold Inflation psi
5. If you want to lower the potential for a belt separation due to the multi-axle Interply Shear increase your CIP to the tire sidewall pressure.


This link is a Google search on Interply Shear if you want to learn more.
