Rock crawling demands maximum traction and tire conformity. Lower pressures let your tires wrap around obstacles instead of bouncing off them.
| Setup | PSI Range |
|---|---|
| Standard Wheels | 12-22 PSI (lower for lighter rigs) |
| Beadlock Wheels | 6-12 PSI with beadlocks |
Lower gradually until wheelspin calms. The tire should visibly bulge at the contact patch. Avoid pinching sidewalls on sharp ledges -- pick your line carefully. Go slow and let the tires conform to the rocks.
Going too low without beadlocks risks popping a bead. Never drop below 12 PSI on standard wheels. Watch for sharp edges that can cut sidewalls.
