Download as PDF



1.Weigh the trailer (under wheels) "Wheel Weight"
2.Obtain "Tongue Weight" (Actual)
3.Measure distance from tongue to axle, or to
center between Dual Axle Set (D)
4.Determine Total Weight
Total Weight=Tongue Weight + Wheel Weight
If tongue weight is greater than 10% of
Total Weight, decrease distance D by X where

X=(Tongue Weight - 10% Total)Times D
Total Weight
If tongue weight is less than 10% of
Total Weight, increase distance D by X where

X=( 10% Total - Tongue Weight )Times D

Example #1 - Tongue greater than 10% of Total Weight
Example #2 - Tongue less than 10% of Total Weight

Move the Axle(s) toward theTongueof the trailer approximately 6.5"
New D=264 - 6.5"=257.5"
Move the Axle(s) toward theRear of the trailer approximately 17"
New D=D + 17"=264 + 7=281"
