Cracking the Code: Understanding Trailer Sway and Tongue Weight Physics

Trailer sway occurs when the weight distribution of a trailer is not properly balanced. If too much weight is located towards the rear, the trailer is more prone to sway and the motion can become progressively worse. On the other hand, having weight pushed forward helps counteract sway and provides stability. The ideal tongue load for a trailer is between 10% and 15% of its weight, ensuring a downward force on the hitch. Proper load distribution and understanding the physics behind trailer sway are crucial for safe towing.
