How to Tighten Wheels
G&S Chassis recommends that you tighten the wheel nuts on your caravan prior to every journey.
WARNING
Incorrectly tightened or neglected wheel nut tension may result in wheel loosening and/or detachment.
Consequences may include property damage, personal injury or death. If you have any concerns in
relation to wheel nut tension, you should contact a professional immediately.
A correctly calibrated tension wrench should be used for this work.
Required wheel nut torque = 135 Nm. Each wheel stud must be tightened in the following sequence:
Five Stud Wheels Six Stud Wheels
Loosen each nut approximately ¼ turn before
tightening. If any nut is found to be loose or
missing, the cause must be investigated, identified
and rectified.
Check and tighten nuts in the order: 1, 3, 5, 2, 4
Loosen each nut approximately ¼ turn before
tightening. If any nut is found to be loose or
missing, the cause must be investigated, identified
and rectified.
Check and tighten nuts in the order: 1, 4, 2, 5, 3, 6.

Maintaining the correct inflation pressure in your caravan wheels will maximise the lifespan of the tyres,
reduce shock to the caravan and improve towing stability. Generally, over-inflated tyres have a higher chance of
puncturing, transfer more vibration and shock to the caravan and the bouncing effect can cause instability and
sway while towing. Under-Inflated tyres may also result in instability and the additional load on the sidewalls of the
tyres can cause them to de-laminated or bulge.
Keep your tyres inflated to the correct pressure by using this tyre pressure calculation and instructions below.
“Check the sidewall of the tyres for the cold Inflation Pressure at Maximum Load (either kPa or psi) and the
Maximum Tyre Load Rating (kg). Always use the “SINGLE” load and pressure ratings.”
Alternatively, use the tyre inflation calculator on the G&S Chassis website www.gnschassis.com.au
to check that the calculated tyre inflation pressure is correct by inflating the tyres to the calculated tyre pressure
at cold temperature (caravan should not have been used for at least 2 hours). Then tow the caravan loaded to the
weight used in the calculation for 100km (preferably highway driving to get heat into the tyres) and then measure
the actual tyre pressure immediately after stopping. This will give you the hot inflation pressure. The hot reading
will be 6psi (42kPa) warmer than the cold reading if the inflation temperature is correct. IF the hot pressure is more
than 6psi the cold pressure, the tyre inflation pressure is too low, so inflation pressure needs to be increased. If the
hot pressure is less than 6psi the cold pressure, the tyre inflation pressure is too high, so inflation pressure needs
to be decreased.
