AIRING DOWN 101
TRACTION STARTS HERE
One of the simplest and most effective ways to improve your vehicle’s off-road performance doesn’t require expensive modifications or specialized equipment.
It starts with your tires.
Learn why airing down improves traction, when to reduce tire pressure, how to use Staun Tyre Deflators, and why having a reliable air compressor is essential before heading onto the trail.
5280 OFFROAD SAFETY RULE
IF YOU AIR DOWN, YOU MUST AIR BACK UP!
Never reduce your tire pressure unless you have a reliable way to reinflate all four tires before returning to normal road driving.
For vehicles equipped with 30–37-inch off-road tires, we strongly recommend a quality, heavy-duty air compressor designed for repeated inflation of larger tires.
WHAT IS AIRING DOWN?
Airing down is the process of intentionally reducing the air pressure in your vehicle’s tires before driving off-road.
Most vehicles operate at higher tire pressures on paved roads to support vehicle weight, maintain predictable handling, minimize heat buildup, and promote even tire wear.
However, those same pressures aren’t always ideal when traveling over rocks, loose dirt, gravel, sand, or uneven terrain.
By reducing tire pressure appropriately, we allow the tire to become more flexible and better conform to the terrain beneath it. This can improve traction, ride comfort, and vehicle control.
At 5280 OFFROAD, airing down is part of our standard trail preparation. It’s one of the first skills we introduce to students because understanding your tires is fundamental to becoming a capable and responsible off-road driver.
5280 OFFROAD TIP
Better traction begins before you ever engage four-wheel drive.
BENEFITS OF AIRING DOWN
INCREASED TRACTION
Reducing tire pressure allows the tire to flex and conform more effectively to uneven terrain.
This can increase the tire’s effective contact area and help the tread maintain traction on rocks, loose dirt, and other irregular surfaces.
Improved traction often means less wheelspin and better control when climbing or navigating obstacles.
BETTER OBSTACLE CONTROL
An appropriately aired-down tire can conform around rocks and obstacles instead of remaining relatively rigid.
This can improve traction during slow, technical maneuvers and reduce the need for excessive throttle or momentum.
Better traction supports smoother, more controlled obstacle navigation.
IMPROVED RIDE COMFORT
Lower tire pressure allows the tire to absorb more of the bumps and vibrations encountered on rough trails.
This can reduce harshness from rocks, washboards, and uneven terrain, resulting in a smoother ride for both driver and passengers.
Your tires are an important part of your vehicle’s suspension system.
IMPROVED FLOTATION
On soft terrain such as sand, reducing tire pressure can increase the tire’s footprint and help distribute the vehicle’s weight over a larger area.
This can reduce sinking and improve the vehicle’s ability to maintain forward movement.
Proper throttle control is still essential to prevent digging into soft terrain.
WHEN SHOULD YOU AIR DOWN?
Airing down can improve traction, comfort, and control across a variety of off-road conditions. However, not every trail requires reduced tire pressure. The decision depends on terrain, vehicle weight, tire construction, and anticipated driving speeds.
ROCKY TRAILS
Lower tire pressures can improve traction by allowing tires to conform to rocks and uneven surfaces.
This is especially beneficial during slow-speed obstacle navigation, rocky climbs, and technical trails.
WASHBOARD ROADS
Moderately reduced tire pressure can help absorb repetitive bumps and reduce vibration.
Always adjust your speed to maintain vehicle control and avoid excessive tire heat buildup.
MUD
Airing down may improve flotation and traction in some muddy conditions.
However, performance depends on mud depth, consistency, tread design, and the underlying terrain.
DIRT & GRAVEL
Moderate reductions in tire pressure can improve ride comfort on rough dirt and gravel roads.
However, significant pressure reductions are not appropriate for higher-speed travel.
SAND
Reducing tire pressure can increase the tire’s footprint, helping distribute vehicle weight over a larger area.
This improves flotation and may reduce the tendency to dig into soft sand.
SNOW
Moderately reduced pressure may improve flotation in deep, soft snow.
On packed snow or ice, reduced pressure isn’t necessarily beneficial. Tire design and appropriate traction equipment are often more important.
5280 OFFROAD SAFETY REMINDER
Not every trail requires airing down. Always consider your vehicle’s weight, tire construction, terrain, and driving speed before reducing pressure.
HOW MUCH SHOULD YOU AIR DOWN?
One of the most common questions we hear from students is, “What PSI should I air down to?”
The answer depends on your vehicle, tires, and the conditions you’ll be driving in.
There is no single tire pressure that’s appropriate for every off-road vehicle.
A lightly loaded Jeep Wrangler and a heavily loaded full-size pickup may require significantly different pressures, even when equipped with similar-size tires.
The goal isn’t to run the lowest pressure possible. It’s to find the right balance of traction, control, and tire safety.
FACTORS THAT DETERMINE YOUR OFF-ROAD PRESSURE
-
Vehicle weight and cargo load
-
Tire size and construction
-
Tire load and capacity
-
Wheel width and design
-
Terrain conditions
-
Anticipated Driving speed
-
Tire manufacture recommendations
-
Conventional vs. beadlock wheels
-
Vehicle modifications
-
Driver experience
5280 OFFROAD SAFETY REMINDER
LOWER ISN’T ALWAYS BETTER!
Excessively low tire pressure increases the risk of losing a tire bead, damaging a sidewall, or striking an obstacle with the wheel.
Insufficient pressure can also compromise a tire’s ability to support the vehicle’s weight.
Always select pressures appropriate for your specific vehicle, tire construction, load, and terrain.
THE 5280 OFFROAD APPROACH
At 5280 OFFROAD, we recommend beginning conservatively when learning to air down.
Before selecting an off-road tire pressure, consider the following:
-
Know your normal road pressure.
Understand the appropriate highway inflation pressure for your vehicle and tire configuration. -
Understand your tires.
Tire size, construction, load rating, and wheel configuration all influence how much pressure can safely be reduced. -
Consider your vehicle’s weight.
A heavily loaded vehicle generally requires more pressure than a lighter vehicle using comparable tires. -
Evaluate the terrain.
Rocky trails, loose dirt, sand, and other surfaces may benefit from different pressure adjustments. -
Consider your speed.
Lower pressures increase tire flex and heat buildup. Reduced pressure requires appropriately reduced driving speeds. -
Start conservatively.
Make gradual adjustments within the tire and wheel manufacturers’ applicable operating limits rather than immediately selecting an extremely low pressure. -
Monitor your tires.
Watch for excessive sidewall deformation, unexpected air loss, unusual handling, or signs of tire damage. -
Be prepared to reinflate.
Always carry a reliable compressor capable of restoring all four tires to appropriate road pressures.
When in doubt, consult a qualified tire professional before making significant pressure reductions.

Proper tire pressure is about achieving useful traction while maintaining an appropriate margin of safety.
STAUN TYRE DEFLATORS
OUR EQUIPMENT OF CHOICE
At 5280 OFFROAD, we believe in using equipment that’s dependable, practical, and easy to operate.
That’s why we use Staun Tyre Deflators.
These automatic tire deflators are part of our standard trail preparation. They’re equipment we personally use, trust, and confidently recommend to our students.
Rather than manually releasing air from each tire and repeatedly checking pressures, Staun deflators allow us to preset a target pressure and automatically deflate all four tires simultaneously.
Once properly calibrated, they make airing down faster, easier, and more consistent.
It’s not equipment we simply recommend. It’s equipment we use.
Staun automatic tire deflators attach directly to your tire’s valve stems.
Once activated, they release air until the preset stopping pressure is reached.
A standard set includes four deflators, allowing all four tires to be aired down simultaneously.
Each deflator can be adjusted to a desired pressure within its supported operating range.
For the standard-range Staun deflators we use, that range is 6–30 PSI.
Important: The factory preset pressure may not be appropriate for your vehicle. Always calibrate the deflators to your intended pressure and verify the results with a reliable tire pressure gauge.
WHY WE CHOOSE STAUN
AUTOMATIC OPERATION
Properly calibrated deflators automatically stop releasing air at their preset pressure.
FOUR TIRES AT ONCE
A set of four allows simultaneous deflation, saving time during trail preparation.
DURRABLE CONSTRUCTION
Precision-machined brass construction designed for repeated use.
CONSISTANT PRESSURES
