| How to Determine the Correct Axle Position |
Axle position is important for proper weight distribution.
- Weigh the trailer (under wheels) "Wheel Weight"
- Obtain "Tongue Weight" (Actual)
- Measure distance from tongue to axle. or to C between Dual Axle Set (D)
- 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
Total Weight

Example #1
Tongue greater than 10% of Wheel Weight
Tongue Weight = 1025#
Wheel Weight = 7200#
D = 264"
Total Weight = 8225#
% Tongue Weight = 1025 / 8225 = 0.1246 or 12.5%
"X" = 1025 - 822.5 / 8225 Times 264 = 6.499"
Move the Axle(s) toward the Tongue of the trailer approximately 6 1/2"
New D = 264 - 6 1/2" = 257.5 |
Example #2
Tongue less than 10% of Wheel Weight
Tongue Weight = 300#
Wheel Weight = 8200#
D = 264"
Total Weight = 8500#
% Tongue Weight = 300 / 8500 = 0.035 or 3.5%
"X" = 850 - 300 / 8500 Times 264 = 17"
Move the Axle(s) toward the rear of the trailer approximately 17"
New D = D + 17" + 264 + 17 = 281" |
