Always check tyre pressures, with COLD tyres (after vehicle has stood for three hours or more, or driven less than 2 km) and should be checked weekly or before any extended trip.

When checking tyre pressure, visually inspect tyres for excessive wear, sharp objects embedded in the tyre or damage to the sidewalls.

Important: 

   • Clean valve exterior, prior to applying air pressure nozzle when inflating tyre.
   • Always install valve caps to keep out dust and water.
