Notes

Heavier than JL due to truck bed. Longer wheelbase needs longer hoses. On 35" E-rated, same ranges as JL. Rubicon trim has lockers, disconnecting sway bar, and factory beadlock option.

Hose Recommendation: Quad+ 155" (MFQ+) -- longer wheelbase than JL. Shop MORRflate hose kits to air down all tires at once.

How to Air Down Your Jeep Gladiator JT

  1. Park on a flat, stable area before the trailhead.
  2. Set the parking brake and check current tire pressure with a gauge.
  3. Use your deflator or MORRflate system to release air to your target PSI (see table above).
  4. Adjust all four tires evenly. Drive a short distance, recheck, and fine-tune.
  5. Re-inflate before returning to pavement. Low pressures at highway speeds cause heat buildup and blowout risk.
Safety: Always re-inflate before returning to pavement. Running low pressures at highway speeds can cause heat buildup, sidewall damage, and even a blowout.
