Trailer load
Only drivers with sufficient experience in towing large or heavy trailers should operate the vehicle with the full permitted trailer load.
The permitted trailer loads depend on the type of vehicle and engine and must not be exceeded. The permissible trailer load is recorded in the vehicle documents. In the absence of a special entry, the value of the permissible trailer load is applicable for slopes with a slope of not more than 12%. These allowable values characterize the capabilities of the car only for the specified slopes at an altitude of up to 1000 m above sea level (NN - normal zero). At high altitudes, due to rarefied air, engine power is reduced - to calculate the maximum permissible trailer load, it is necessary to reduce its standard value by 10% for every 1000 m above sea level.
Note: When driving on roads with a slight incline (less than 8%) there is no need to reduce the trailer load.
Support load
Support load (drawbar vertical load) - this is the force with which the trailer presses on the coupling support of the tow hitch. This force can be adjusted by distributing the weight when the trailer is loaded.
The maximum permissible drawbar load of the towing vehicle is indicated on the type plate of the trailer tow hitch and in the documentation of the vehicle. You should try to always maintain this value, especially for heavy trailers.
Attention: The support load must be at least 25 kg!
When measuring the drawbar load, it is necessary to set the drawbar of the loaded trailer to the same height at which it will be after attaching the trailer to the loaded vehicle. This is especially important for two-axle trailers.
Rear axle load
When the trailer is attached and the towing vehicle is fully loaded, including the weight of all passengers, the load on the rear axle must not exceed the permissible load (see specs). If, nevertheless, the permissible load on the rear axle is higher, do not exceed the speed of 100 km/h.
Note: If the MPC sets lower speeds when operating a vehicle with a trailer, follow the Rules.
Tire pressure
When operating a vehicle with a trailer, you should constantly monitor the maintenance of the appropriate air pressure in the tires, depending on the load of the vehicle and trailer (see specs), make appropriate adjustments if necessary.
