Essential Air-Management Gear
Build a complete, compact air kit
- Compressor: choose CFM for tyre size & rig weight; look for duty cycle & auto-stop.
- Deflators: set-and-forget for big drops; manual bleed for small tweaks.
- Gauge: quick, accurate verification — analog survives cold and dirt.
- Hose & chucks: screw-on or lightning-lock; avoid leaky push-fits.
- Repair: quality plug kit, valve cores/caps, bead lube, and a valve-tool.
- Power: heavy clamps, fused; keep cables away from fans and belts.
- Storage: a single bag you can toss between vehicles.
Compressors: what matters
CFM & duty cycle
CFM (flow) sets your speed; duty cycle dictates how long the motor can run without overheating. Dual-cylinder units with 40–60% duty at high CFM are ideal for LT tyres and heavy builds.
| Rig/tyre | Recommended CFM | Notes |
|---|---|---|
| Light / P-metric 29–32″ | 3–5 CFM | Short transits, occasional use |
| Medium / LT 32–34″ | 5–8 CFM | Balanced speed & size |
| Heavy / LT 33–37″+ | 9–11 CFM | Fast reinflation; convoy-friendly |
Power & placement
- Use battery clamps (not cig sockets) for high draw.
- Engine idling supports voltage and cooling.
- Keep intake off the dirt; don’t block radiator airflow.
Deflators & gauges: accuracy without fuss
Automatic deflators
Great for sand entry or group staging: clip on all four, they stop at your set PSI while you spot lines and organize comms.
Analog gauge with fast bleed
Stays readable in cold, no batteries, and perfect for 2–3 PSI tweaks when moving between gravel, rock, and hardpack.
Hoses, chucks & 4-tyre kits
Single vs. 4-tyre inflation
4-tyre systems equalize pressures and halve touch time. Single-hose is simpler and packs smaller. Either way, use quality seals and strain-relief on couplers.
Chucks that don’t fight you
- Screw-on or locking “lightning” chucks prevent hiss and arm fatigue.
- Carry spare valve cores and metal caps.
Repair & spares
- Tyre plug kit with T-handle tools and quality sticky strings.
- Valve core tool, spare cores/caps, small bottle of bead lube/sealer.
- Board and shovel for sandy reseats; never put hands near the bead while inflating.
Recommended field setups
| Rig | Compressor | Deflation | Gauge | Extras |
|---|---|---|---|---|
| Light (<2.2t) | 5–8 CFM portable | Manual bleed or auto deflators | Analog 60–100 PSI | Single hose, plug kit |
| Medium (2.2–3.0t) | 8–10 CFM dual-cyl | Auto deflators (set 14–18 PSI) | Analog 100 PSI w/ quick bleed | Locking chuck, spare cores |
| Heavy (>3.0t) | 10–11 CFM + auto-stop | Auto deflators | Analog 100 PSI | 4-tyre kit, heavy cables |
