Why does my car shake when I'm stopped at the lights?
A car shaking at idle usually comes down to four causes. Here's how to read what your car is telling you and which ones can wait vs. which ones can't.
How to calculate your towing capacity
With summer well and truly here, there’s no better time to dust off your caravan, boat or camping trailer and hit the road. But before you do, it’s essential to know your vehicle’s towing capacity for both safety and legal reasons. Towing capacity is not a one-size-fits-all metric, and it’s important to consider the various factors that can affect how much weight your vehicle can haul. As responsible drivers, it falls on us to understand the limitations of our vehicles, safeguarding ourselves and others when out on the open road.
Understanding towing capacity
Towing capacity can be described as the maximum weight a vehicle can tow without compromising performance or safety. There are many components within a vehicle that contribute to its towing capacity; most notably the engine, which produces power, and the transmission, which directs this power to the wheels. The suspension system and brakes contribute to stability and control (crucial for towing heavy loads), and a robust frame ensures structural integrity, even under immense stress.
Some of our favourite vehicles for towing include the Toyota Landcruiser, Nissan Patrol, and Ford Ranger. With plenty of capable options to choose from, we suggest doing your research to find a vehicle that best aligns with your specific needs and budget.
Determining your vehicle’s towing capacity
Understanding your vehicle’s towing capacity is essential for anyone planning on hauling caravans, boats or trailers safely. Primarily, this information can be found in your vehicle’s owner’s manual, where detailed specifications, including towing capacity, are outlined. The owner’s manual also provides insights into critical factors such as engine power, transmission capabilities, suspension systems, and chassis strength, all tailored to the specific make and model of your car. Locating your car’s vehicle identification number (VIN) is also beneficial as this can be used to gain further insights into your vehicle’s factory specifications that influence towing capacity.
- In Australia the legal unbraked towing capacity of a vehicle is 750kg - this applies to trailers that do not have their own independent braking system.
- The maximum braked towing capacity in Australia is 3500kg - applying to trailers that do have brakes and are therefore better equipped to handle heavier loads.
Understanding weight
Understanding the weight of what you’re towing is essential when calculating your towing capacity. The Gross Trailer Weight (GTW) represents the total weight of your trailer and its contents. The Gross Combination Mass (GCM) is the maximum weight of your vehicle and trailer combined. Understanding these factors is vital to ensure that you stay within the prescribed towing limits of your vehicle.
