Effects of Low Tongue Weight on Braking and Trailer Sway
Too little tongue weight can make a trailer sway, sometimes in response to a wind gust, a passing truck, or a small steering input. The effects of low tongue weight begin with reduced stability: a trailer’s tongue weight should be 10-15% of its total weight. A weight-distribution system can help balance loads across the axles, but it can’t fully correct improper tongue weight.
