Tire pressure gauge & deflator

Tires & Wheels

An accurate gauge (often with a deflator) for airing down to terrain pressure and back up safely.

Approx. cost
$10–$60
Weight
2–8 oz
Used in
1 kit

Purpose

Set tire pressures deliberately — traction off-road comes from airing down, and safety on-road from airing back up.

Used in kits

Alternatives

  • Dash TPMS readout— Coarse and slow to update; fine for warnings, not for setting pressures.
  • Automatic deflators— Preset screw-on deflators speed up airing down four tires.

Maintenance notes

  • Check the gauge against a known-good reference yearly; keep the chuck free of grit.

Buying considerations

  • A 0–60 PSI analog or digital gauge with 1 PSI resolution covers trucks and trailers.
  • A built-in bleed valve turns airing down from chore to routine.
