to excessive heat build up. If a trailer tire is under-inflated, even for a
short period of time, the tire could suffer internal damage.
High speed towing in hot conditions degrades trailer tires significantly.
As heat builds up during driving, the tire’s internal structure starts to
breakdown, compromising the strength of the tire. It is recommended to
drive at moderate speeds.
Statistics indicate the average life of a trailer tire is about five years
under normal use and maintenance conditions. After three years,
replacing the trailer tires with new ones should be considered, even if the
tires have adequate tread depth. Some experts claim that after five years,
trailer tires are considered worn out and should be replaced, even if they
have had minimal or no use. This is such a general statement that it may
not apply in all cases. It is best to have your tires inspected by a tire
supplier to determine if your tires need to be replaced.
If you are storing your trailer for an extended period, make sure the tires
are fully inflated to the maximum rated pressure and that you store them
in a cool, dry place, such as a garage. Use tire covers to protect the
trailer tires from the harsh effects of the sun.

RAILER
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 particular axle can weigh. If
there are multiple axles, the GAWR of each axle will be provided.
If your trailer has a GVWR of 10,000 pounds or less, there is a vehicle
placard 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.
Cargo can be added to the trailer, up to the maximum weight specified on
the placard. The combined weight of the cargo is provided as a single
