Wheels and Tyres
Highway
Your camper 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.
Recommended highway pressure at tare weight of the camper is 62psi
Recommended highway pressure at ATM of 3000kg is 77psi
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 camper 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 camper.
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 camper 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.
