Every serious four wheel driver knows that airing down is the first step to any successful adventure. That process used to take ages and involved lots of kneeling near the tyres. Now I use the Boss Air deflators from CampBoss. These are a true set and forget solution for quick tyre pressure changes.
The good
- Fastest air down method
- Auto stop at preset PSI (5 to 30)
- Laser etched gauge for setting
- Nickel plated, anti-corrosive body
- 114 gram kit weight
The not-so-good
- Requires initial precise setting
- Gauge must be kept clean
- No option for high PSI road use
They are designed to automate all the hard work. This simple automation gets you onto the sand or rock track much faster. I have been using these on my vehicle for a while now. Let’s dive into why the campboss tyre deflators make air down routines so much easier.
What You’re Getting
Automatic, high speed tyre deflator set covering a 5 PSI to 30 PSI range with durable, anti-corrosive construction for quick off-road tyre pressure changes.

First impressions
The moment I take these deflators out, I notice their compact size and solid construction. The entire kit feels substantial in my hand. They come in a nice little neoprene carry pouch. This protective storage pouch is well-made and keeps everything neat and tidy. Inside the pouch, each of the four deflators sits perfectly in its own separate slot. This stops them from rattling around when I drive over rough corrugated tracks.
The small carabiner on the bag is a handy little feature. I can easily clip the deflator kit onto my larger Tyre Tools bag or my recovery kit handle. The deflators themselves are a chunky piece of brass and metal. They look much more substantial than other deflators I have used.
Materials & Build Quality
CampBoss uses superior quality materials for these deflators. The main body features an anti-corrosive nickel plated coating. This is vital because the deflators constantly face exposure to mud, water, and sand. The internal components are all made from quality stainless steel. This means the critical seals and springs resist rust and corrosion over time.
I appreciate the laser-etched gauge scale on the stem. This feature provides a measure of accurate reading for precise pressures. There is no guessing where I set the PSI level. The overall construction feels like a single, tightly machined unit. I have confidence that these deflators will handle the abuse of off-road touring for many seasons to come.
Ergonomics & Weight
The entire kit, including the protective carry pouch, weighs just 114 grams. This makes them incredibly light and easy to throw into any glove box or 4WD Storage system. Their compact size is a huge advantage. They do not take up much valuable space when packed away. Setting these deflators is truly the best part of the design. You simply unscrew the top adjustment cap first. This reveals the core body which acts as the PSI setter.
You align the bottom edge of the deflator body to the desired PSI level indicated on the inner stem. For example, if I want 18 PSI, I just rotate the body until it lines up perfectly. Once the body aligns to the right setting, I screw the top cap back on solidly. This system removes the guesswork I find with fiddly screw-in deflators. The large knurled surface on the brass body gives me an excellent grip. This makes them easy to handle even with cold or muddy hands.
Performance & Features
The primary feature of the Campboss tyre deflators is the pure speed of deflation. The design takes about half the time compared to the older valve removal styles. Once they are preset, the process is truly effortless. I screw them onto the tyre valve, and the air immediately rushes out with a satisfying hiss. They are completely a “set and forget” method. They automatically shut off when they reach the preset PSI. I set mine for 15 PSI for deep sand driving. They stop dead on that reading every single time I use them.
The 5 PSI to 30 PSI range covers all common off-road and touring requirements. The locking ring is effective. It maintains the pre-set pressure for the next use, even after months of tough vibrations. This reliability means I can trust the pressure reading without constantly needing to re-calibrate. The anti-corrosive coating on the nickel plating also contributes to long term, reliable performance. It ensures the threading remains smooth and easy to use.
Gear That Complements Your 4WD Setup
Once you have your Campboss tyre deflators dialled in, you need to ensure the rest of your air management system is just as efficient. Head over to our reviews on Tyre Tools to find the most accurate pressure gauges for checking your PSI baseline.
We also have detailed reviews of Air Compressors to quickly get your tyres back up to highway pressure after a run on the beach. Finally, pair these deflators with a great set of Recovery Boards so you are completely prepared for soft terrain and unexpected recoveries.
The Boss Air deflators are a simple, high quality solution to one of four wheel driving’s biggest chores.
They deliver fast, accurate deflation thanks to their superior internal components and smart design. The straightforward setting mechanism, where you align the body with the laser etched stem, removes all the guesswork. I especially appreciate the sturdy, nickel plated build and the practical, protective neoprene pouch. If you are tired of manually deflating your tyres, these deflators are a massive time saver. They allow you to spend less time kneeling and more time enjoying the track ahead.
These deflators are best for the frequent adventurer who demands both speed and precision in their gear. They are ideal for touring vehicles that switch frequently between highway and soft off-road conditions like sand or light mud. The automatic shut off feature ensures all four tyres hit the exact same pressure every time. This consistency improves both safety and overall performance on the track.
Absolutely. While these are a premium option compared to manual gauges, the time they save is truly priceless. The durable nickel plating and quality stainless steel internals promise excellent longevity. The one time setup and automatic, fast deflation make the Boss Air deflators a worthwhile investment for serious off-road travellers who prioritize convenience and accuracy over low cost.
