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.
