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
41
psi
Recommended highway pressure at ATM is 51psi
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.
