Airing Down (Lowering Tyre Pressure Off-Road)
Airing down means reducing tyre pressure for sand, mud or rocks to lengthen the tyre footprint and improve grip.
What is Airing Down (Lowering Tyre Pressure Off-Road)?
Lower pressure lets the tyre spread over soft ground. It also gives a more comfortable ride on rough tracks. A gauge and deflator make it quicker. Many off-road guides suggest reducing pressure in steps and testing grip.
How it works
A softer tyre flattens and grips over a larger area, reducing sinking.
Why it matters for your car
Drive slowly and avoid sharp turns, as the tyre can come off the rim. Re-inflate to road pressure before driving on tarmac.
