Calculating Correct Weight Distribution Setup for Your Trailer
Spring bars can change the scale reading, but they don’t change the trailer’s underlying tongue force. For calculating the correct weight distribution setup, measure tongue weight with the bars disengaged; a trailer’s tongue weight should generally fall within 10% to 15% of its total loaded weight. Once the bars are engaged, they redistribute load among the trailer axles and the tow vehicle’s front and rear axles, so those scale readings describe a different load balance.
