Wheels and Tyres
Highway
Your caravan is fitted with 16” wheels and 265/75 R16 Goodride Tyres. The tyres are a “Light Truck” tyre with a mud
terrain tread and a maximum load rating on single axle of 1550kg at 80psi. See the tyre pressure recommendation
chart on
page 16.
Off Road
Off road driving requires lower tyre pressures and lower speeds. When driving on rough and corrugated road,
a reduction of speed and controlled deflation of tyres is required to protect the caravan and its suspension from
damage. In extreme circumstances tyre pressures may be reduced significantly. When lowering from highway
pressure, a rule of thumb is to reduce your speed by the same percentage as the lowering of tyre pressure.
Because off road conditions can vary greatly, you must lower your pressures and reduce speed until vibration and
shock through the suspension is at a moderate level to suit the conditions you are experiencing, and the loaded
weight of your caravan.
WARNING: When returning to the highway or when increasing speed, you must reinflate the tyres
to correct highway pressures. Failure to reinflate can cause severe handling problems resulting in
injury or death.
Suspension
Your Caravan is fitted with quality independent trailing arm suspension with dual shock absorbers. This design is
ideal for the full range of use on and off road however, there are limitations in prolonged use of corrugated and rough
road.
Shock Absorbers & Bushes
The function of shock absorbers is to turn kinetic energy into heat and dampen the rebound in the suspension
to keep the tyre in contact with the road. During prolonged periods on corrugated and rough roads it is possible
to overheat shock absorbers to the point of failure (shock fade). Best practice is to take regular breaks and allow
both the shock absorbers and suspension bushes to cool. Overheating the bushes through prolonged driving on
corrugations can soften the thermoplastic and cause premature wear and/or deformation of the bush. On severely
rough roads stop regularly up to every hour to allow components to cool.
