Determining Load Limit of Trailer
Determining the load limits of a trailer includes more than
understanding the load limits of the tires alone. On all
trailers there is a Federal certification/VIN label that is
located on the forward half of the left (road) side of the unit.
This certification/VIN label will indicate the trailer’s Gross
Vehicle Weight Rating (GVWR). This is the most weight
the fully loaded trailer can weigh. It will also provide the
Gross Axle Weight Rating (GAWR). This is the most a the
axle can weigh.
There is a vehicle placard (Figure 56) located in the same
location as the certification label described above. This
placard provides tire and loading information. In addition,
this placard will show a statement regarding maximum
cargo capacity.
If additional work items (hoses, tools, clamps etc.) are going
to be added to the trailer, be sure they are distributed evenly
to prevent overloading front to back and side to side. Heavy
items should be placed low and as close to the axle
positions as reasonable. Too many items on one side may
overload a tire.
Excessive loads and/or underinflation cause tire
overloading and, as a result, abnormal tire flexing occurs.
This situation can generate an excessive amount of heat
within the tire. Excessive heat may lead to tire failure. It is
the air pressure that enables a tire to support the load, so
proper inflation is critical. The proper air pressure may be
found on the certification/VIN label and/or on the Tire
and Loading Information placard. This value should never
exceed the maximum cold inflation pressure stamped on
the tire.
Lug nuts are also prone to loosen after first being
assembled. When driving a new trailer (or after wheels
have been
remounted), check to make sure they are tight after the
first 10, 25 and 50 miles of driving and before each tow
thereafter.
Failure to perform this check can result in a wheel parting
from the trailer and a crash, leading to death or serious
injury.
Lug nuts are prone to loosen after initial installation,
which can lead to death or serious injury.
Check lug nuts for tightness on a new trailer or when
wheel(s) have been remounted after the first 10, 25 and
50 miles of driving.
WARNING - Lug Nut Loosening
Improper lug nut torque can cause a wheel parting from
the trailer, leading to death or serious injury.
Be sure lug nuts are tight before each tow.
WARNING - Improper Lug Nut Torque
Improper tire pressure can result in a blowout and loss
of control, which can lead to death or serious injury.
Be sure tires are inflated to pressure indicated on side
wall before towing trailer.
