Check Tire Pressure
Although the Aeris tire inflation system is designed to detect and fill a tire that’s leaking during
vehicle operation, STEMCO recommends you inspect the tires for normal wear and damage at
regular intervals and check the tire pressure as follows.
Remove the metal cap from the check port that is provided on each hose. See Figure 35
Figure 35
Check pressure going to each tire using a pressure gauge.
If the tire pressure is correct: Replace fill cap and hand tighten.
If the tire pressure in not correct: Check the following:
Verify that the shut off valve is in open position.
Check all air connections with soapy water solution. If bubbles can be seen,
tighten fittings and check again with soapy water solution.
If pressure is too high release some pressure from the tire and replace the fill cap.
The Aeris system will automatically inflate the tire to correct setting.
Each tire should be checked for correct air pressure 4 times per year.
