Land Rover Discovery: Tyre pressures
- All tyre pressures, including the spare, should be checked regularly using an accurate pressure gauge, when the tyres are cold.
- Pressure checks should be carried
out only when the tyres are cold,
and the vehicle has been
stationary for more than 3 hours.
A hot tyre at, or below, the recommended cold inflation pressure, is dangerously under-inflated.
- Never drive your vehicle if the tyre pressures are incorrect.
- Under-inflation causes excessive
flexing and uneven tyre wear. This
can lead to sudden tyre failure.
Over-inflation causes harsh ride, uneven tyre wear and poor handling.
- Do not drive the vehicle with a leaking tyre. Even if the tyre appears to be inflated, it could be dangerously under-inflated and will continue to deflate. Renew the tyre or contact an approved repairer.
- Under-inflation also reduces fuel efficiency and tyre tread life and may affect the vehicle's handling and stopping ability.
- If the vehicle has been parked in strong sunlight, or used in high ambient temperatures, do not reduce the tyre pressures. Move the vehicle into the shade and allow the tyres to cool before rechecking the pressures.

The tyre information label is located on the driver's side B pillar.
Check the tyres, including the spare, for condition and pressure on a weekly basis and before long journeys.
If tyre pressures are checked while the vehicle is inside a protected covered area (e.g., a garage) and subsequently driven in lower outdoor temperatures, tyre under-inflation could occur.
A slight pressure loss occurs naturally with time. If this exceeds 14 kPa (0.14bar/2 psi) per week, have the cause investigated and rectified by qualified personnel.
If it is necessary to check the tyre pressures when the tyres are warm, you should expect the pressures to have increased by up to 30 - 40 kPa (0.3 - 0.4 bar/4 - 6 psi). Do not reduce the tyre pressures to the cold inflation pressure under these circumstances. Allow the tyres to cool fully before adjusting the pressures.
The following procedure should be used to check and adjust the tyre's pressures:
- To avoid damaging the valves, do not apply excessive force or sideways force on the gauge/ inflator.
- To avoid damage to TPMS valves, it is recommended not to use rigid tyre inflation wands. This is to avoid the risk of excess leverage and sideways pressure on the valve.
- Remove the valve cap.
- Firmly attach a tyre pressure gauge/ inflator to the valve.
- Read the tyre pressure from the gauge and add air, if required.
- If air is added to the tyre, remove the gauge and re-attach it before reading the pressure. Failure to do so may result in an inaccurate reading.
- If the tyre pressure is too high, remove
the gauge and allow air out of the tyre
by pressing the centre of the valve.
Refit the gauge to the valve and check the pressure.
- Repeat the process, adding or removing air as required, until the correct tyre pressure is reached.
- Refit the valve cap.
TYRE VALVES
Keep the valve caps screwed down firmly to prevent water or dirt from entering the valve. Check the valves for leaks when checking the tyre pressures.
Do not twist or bend the valves when attaching a pressure hose or gauge, as damage may result.
