How to Stop Trailer Sway
Understanding the Dynamics of Trailer Sway
The Causes of Trailer Sway and Its Dangers
Trailer sway, a side-to-side motion that can escalate from a gentle sway to a dangerous fishtail, is a concern for every truck owner. It's critical to recognize that improper weight distribution is a primary culprit, as it compromises the stability of your vehicle combination. Too much weight at the rear of a trailer or uneven weight distribution can shift the centre of gravity and increase the likelihood of losing control. For safe driving, maintaining a balance of weight is key. To combat this, ensure the hitch weight is approximately 10-15% of the total trailer weight and distribute cargo evenly.
The Impact of Wind Bursts and Side-Winds From Large Passing Vehicles
The power of winds—a strong gust or the blast from a large, speeding vehicle—can jolt a trailer into an unstable sway. Commercial vehicles, including tractor-trailers, crate a sizable airflow disruption—a gust of wind that can unsettle your trailer. To calm trailer sway, a firm grip on the wheel and a steady, moderate speed can help maintain control. In heavy winds, reducing speed and avoiding sudden movements are crucial actions.
Consequences of Exceeding Trailer Weight Limits
Overloading a trailer is another mistake that can lead to sway and potentially, an accident. It's essential to know your vehicle's max trailer and load-carrying capacity, which is typically provided by tow vehicle manufacturers. Excessive weight not only places stress on the tow vehicle brakes but also interferes with the trailer's ability to follow the towing vehicle smoothly. Weigh your rig at the closest CAT-certified scale; the accuracy of this step cannot be overstressed. Remember, towing within your vehicle's specified tow ratings is a foundational principle of trailer sway prevention.
When transporting heavy loads, whether it’s a 25,000-pound trailer or a compact adventure trailer, consider Vigor Air Ride air suspension kits for improved stability and weight distribution. This simple device can significantly enhance your towing experience by managing weight in hazardous conditions and mitigate the pendulum effect that contributes to trailer sway.
To ensure you're equipped for any situation on the road, it's wise to explore Vigor Air Ride's selection of towing essentials. The correct gear can transform unstable driving conditions into a controlled and confident journey.
