Tyre pressure basics for off-road driving
Tyre pressure changes how a tyre grips, rides and wears. These are general principles, not a rule for every tyre or vehicle.
Why it matters
- Lower pressure lets the tyre flex and spreads it over more ground on soft or uneven surfaces.
- Pressure that is too low raises the risk of damaging the tyre or rim, or the tyre coming off the rim.
- Pressure that is too high can reduce grip on loose surfaces and make the ride harsh.
Start from the right number
- Use the pressure recommended on the vehicle placard or in the owner’s manual as your baseline.
- Measure when the tyres are cold, before driving.
- Never go below the minimum given by your tyre maker.
Adjust in small steps
- Change pressure gradually and test how the vehicle behaves before changing it further.
- Different terrain, loads and tyres need different pressures, so there is no single correct figure.
Speed, heat and the road
- Reduce your speed when pressure is reduced. Soft tyres heat up quickly.
- Re-inflate to road pressure before tarmac or higher speeds.
Carry the right gear
Carry a reliable gauge and an inflator or compressor. Without a way to re-inflate, do not reduce pressure.
Use the tyre-pressure estimator as a starting point only. It uses rules of thumb, not tyre-maker data.
