Inspect all tyres carefully. If your trailer has not been used for a long time, the tyres may be soft.

If in doubt, contact your local tyre dealer
Check that your vehicle and trailer’s wheel nuts have been tightened to the manufacturer’s specifications. To tighten the nuts, use a torque wrench to the torque recommended by the manufacturer (around 90ft lb or 125Nm). Wheel nuts should then be re-tightened after each 100kms for the first 400kms and checked every 1,000kms, at six month intervals thereafter or after having your caravan serviced.
