What should my PSI be for my rear airbags (2024)

FAQs

What should my PSI be for my rear airbags? ›

Don't overdo or you will rupture the bags. 100psi is the absolute max. I run 70 PSI on the air bags when taking shorter trip without much load.

THE RULES OF THUMB. Start with the vehicle level or slightly above. If you have a motorhome, start with 90 – 100 PSI in the rear. If the front of your vehicle dives while braking, add air to the front air bags.

You should always keep 5 lbs. of air pressure in your air bags to prevent any damage. 5 lbs. will not affect your ride but will ensure your air bags last. This is where an air compressor kit comes in handy, monitoring and maintain the minimum air bag pressure.

Airbags are generally triggered by forces of more than 20 Gs, or 20 times the force of gravity. Depending on the calibration and location of the airbag sensors, crashes in which the car dives into and under an object or vehicle, or accidents in which the vehicle rolls, may not generate enough Gs to trigger the airbags.

The working pressures for air bag lifting systems range from 7 psi up to 145 psi. **Note: Another common unit of pressure used with airbags is "bar”. 1 bar = 100 kPa = 14.5 psi.

Don't exceed the vehicle manufacturer's weight ratings. Failure to do so can result in damage to the air spring assembly, suspension or vehicle in general, and voids your Air Lift air spring warranty. Don't exceed the recommended air pressure (100 PSI in sleeve and bellows style air spring applications).

The usual culprit is improper inflation of the air springs. Both over inflated or under inflated air bags will result in significant ride quality issues.

The maximum recommended pressure is 50PSI, so it's nice to be achieving great results at moderate pressures. We have a full ARB GVM upgrade, and these airbags will likely work best in combination with a quality suspension.

In conclusion, tire pressure is an important factor in keeping your vehicle safe and performing optimally. The recommended tire pressure for most vehicles is between 30-35 PSI (pounds per square inch). A tire with a higher PSI rating such as 40 can have both benefits and risks depending on the driving conditions.

Compressed air use is governed by 1910.242. b, which says that air pressure in direct contact with the skin cannot exceed 210 kPa (30 psi).

How much force is needed to set off airbags? ›

For unbelted occupants, a front airbag will typically deploy when the crash is the equivalent of an impact into a rigid wall at 10-12 mph. For belted occupants, most airbags will deploy at a higher threshold — about 16 mph — because the belts alone are likely to provide adequate protection up to these moderate speeds.

The placard or manual should list the appropriate psi for both the front and rear tires, as they may be different. Most passenger cars' psi requirement will be between 30 to 35 psi, but several vehicles fall outside of that range and every vehicle will have specific requirements.

Air-Bag Classifications

Low-pressure air bags typically operate at 7 to 14 pounds per square inch (psi).

Although your Air Helper Springs are rated at a maximum inflation pressure of 100 psi, this pressure may allow you to carry too great a load on some vehicles. It is best to have your vehicle weighed once it is completely loaded and compare that weight to the maximum allowed.

It is important because of optimum result in saving the lives of passengers in a vehicle, should in case, of any casualty. Under-inflated airbag might cause life threatening damage, while over-inflated airbag might cause outright suffocation of the passenger.

Air bags do not deploy in the billowing cloud-like manner as seen in certain television advertisem*nts. As mentioned above, air bags explode at speeds of 200 MPH for 12 to 18 inches. This is a violent reaction, necessary to have the bag deployed and beginning to slowly deflate when the occupant contacts the bag.

The placard or manual should list the appropriate psi for both the front and rear tires, as they may be different. Most passenger cars' psi requirement will be between 30 to 35 psi, but several vehicles fall outside of that range and every vehicle will have specific requirements.

Shop air used for cleaning should be regulated to 15 psi unless equipped with diffuser nozzles to provide lessor pressure. Goggles, face shields or other eye protection must be worn by personnel using compressed air for cleaning equipment. Static electricity can be generated through the use of pneumatic tools.

But even as it is filling with nitrogen gas, an airbag is already venting so that when the human body makes contact, it's not running into the equivalent of a fully inflated Pirelli P7 radial. In fact, the maximum pressure in an airbag is less than 5 psi—even in the middle of a crash event.
