What causes fishtailing with a trailer?

Any trailer towed with a hitch set behind the rear axle of the tow vehicle can sway or fishtail while driving. The hitch acts as a pivot point in-between the centers of gravity of the two vehicles. Any trailer sway or side-to-side force will turn the vehicle and create an unexpected steering force.

How do I keep my trailer from fishtailing?

What is the main cause of trailer sway?

Wind is the most common cause of trailer sway. When there is a strong force pushing your trailer from one side or the other, it can cause it to sway from side to side.

What to do if you start fishtailing with a trailer?

Should you increase tire pressure when towing?

For towing, tires should be inflated to the max cold pressure listed on the sidewall of the tire.

Why does my trailer swerve?

What causes a trailer to snake?

Snaking is most commonly caused by incidents such as sudden swerving, travelling at high speeds, being overtaken by larger vehicles and strong crosswinds, as well as blown-out tyres and overloading the nose of the caravan.

What do you do when your trailer starts to snake?

Relax and loosen your grip on the steering wheel. Still hold the wheel firmly but relax as much as possible so you're not locking the steering into a fixed position. Reduce your speed. Lift your feet off the pedals, and avoid braking as this will slow the tow car down too quickly for the caravan.

How do I keep my truck from bounce when towing?

You can try shifting some weight in the trailer forward to add some tongue weight and that would help eliminate some of the bounce you are experiencing. Also, make sure you are towing it as level as possible. You may need a different ball mount.

Is 20% tongue weight too much?

Tongue weight should be about 10% to 15% of the total weight of the trailer or gross trailer weight. Too much tongue weight can impair driver control over the vehicle, and too little can lead to sway in the trailer.

Is it better to have too much or too little tongue weight?

Your tongue weight should come in between 10 and 15 percent of the total weight of your loaded trailer, also known as your Gross Trailer Weight (GTW). So if you are hauling a 2,000 pound trailer that's loaded up with 2,000 pounds worth of cargo, your tongue weight should be between 400 and 600 pounds.
