Recommended tire pressures
The following table gives the tire pressures for all recommended tire sizes:
Checking tire pressures
The following procedure should be used
to check and adjust the tire pressures
when cold:
1. Remove the valve cover.
2. Firmly attach a tire pressure gauge or
inflator to the valve.
3. Read the tire pressure from the
gauge. If required, add air to the tire.
4. If air is added to the tire, remove the
gauge from the valve and re-attach it
before checking that the pressure is
correct. Failure to remove and
re-attach the gauge could cause the
gauge to show an incorrect reading.
5. If too much air is added, remove the
gauge from the valve and allow air out
of the tire by pressing the centre of the
valve. Reconnect the gauge to the
valve, and check that the air pressure
is correct.
6. Refit the valve cover.
A slight natural pressure loss occurs with
time. If this exceeds 14 kPa (2 lbf/in
2
) per
week, the cause should be investigated
and rectified.
Note: It is an offence in certain countries
to drive a vehicle with tires that are not
inflated in accordance with the vehicle’s
proper use.
