How to Air Down Your Jeep Wrangler JL / JLU
- Park on a flat, stable area before the trailhead.
- Set the parking brake and check current tire pressure with a gauge.
- Use your deflator or MORRflate system to release air to your target PSI (see table above).
- Adjust all four tires evenly. Drive a short distance, recheck, and fine-tune.
- 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.
