Should I let my tyres down off road?
Usually, yes—but not to a magic internet number. Lower pressure lets the tyre flex and lengthens its footprint, improving traction and ride comfort on sand, rocks and corrugations. The right pressure depends on the tyre, vehicle, load, speed and surface.
Pressure, load and speed must be considered together; seek exact advice for a changed size or construction. BFGoodrich Australia pressure guidance, updated 9 June 2026.
Why road pressure is not off-road pressure
Highway pressure is designed for load, heat and speed on a firm surface. On soft sand it encourages the tyre to dig. On sharp corrugations it makes the tyre and suspension absorb harder impacts. Reducing pressure can improve flotation and let the tread conform to rough ground.
A safer beginner routine
- Start from the vehicle placard and tyre maker’s advice for your load.
- Make small reductions, then reassess traction, steering and sidewall shape.
- Drive smoothly and reduce speed as pressure comes down.
- Carry an accurate gauge, compressor and serviceable spare.
- Reinflate to the appropriate pressure before returning to sealed-road use.
If you are bogging, more throttle is rarely the first answer. Stop before the vehicle sits on its belly, reduce pressure cautiously and clear material from ahead of the tyres.
There is no safe universal PSI. Follow the vehicle and tyre manufacturer’s load guidance and seek training before driving at very low pressures.
