How to Determine Correct Axle Position
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
Tongue greater than 10% of Total Weight

If tongue weight is greater than 10% of Total Weight, decrease distance "D" by "X" where

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

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

Tongue Weight  =

Wheel Weight  =

D  =

Total Weight  =

% Tongue Wgt  =

"X"  =

1025 / 8225

=  0.1246 or 12.5%

1025-822.5 / 8225

X 264 = 6.499"

Move the Axle(s) toward the Tongue of the trailer approximately 6.5"

New D = D - 6.5" = 264 - 6.5" = 257.5"

Tongue less than 10% of Total Weight

If tongue weight is less than 10% of Total Weight, increase distance "D" by "X" where

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

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

Tongue Weight  =

Wheel Weight  =

D  =

Total Weight  =

300 / 8500

=  0.035 or 3.5%

850-300 / 8500

X 264 = 17"

Move the Axle(s) toward the Rear of the trailer approximately 17"

New D = D + 17" = 264 + 17" = 281"
