WEIGHING INSTRUCTIONS

To properly weigh your park trailer, it should first be weighted, including the tongue weight, while
detached from the tow vehicle. This actual overall weight must be less than or equal to the GVWR
for safe operation. If the overall weight is greater than the GVWR, some contents must be removed
until maximum GVWR limitations are achieved. Once the actual overall weight is determined and
the park trailer is within GVWR limits, the following weights should be determined:
1. The weight of complete park trailer, while attached, but excluding the tow vehicle. This will
result in the actual weight which is exerted on all of the park trailer tires. This weight may be
subtracted from the overall park trailer weight (above) to determine actual "tongue" weight.
2. With the park trailer still attached to the tow vehicle, each wheel position should then be
weighed separately to be sure each tire is not overloaded.
TO DETERMINE THE WHEEL POSITION WEIGHT:
• Pull the park trailer onto the scale so that only one tire is on the scale. Record the weight.
Your trailer must remain as level as possible on the scale (even though an axle or side is
not physically on the scale). Obviously, to obtain the side-to-side weights, there must be
enough space on either side of the scale to accommodate the park trailer being partially
off the scale.
• To calculate the opposite side of the trailer wheel position weight, subtract the first side's
weight from the weight determined in step #1.
If there is a difference in the weights on one side of the trailer as compared to weights on the other
side, components (tires, wheels, brakes, springs, etc.) on the heavier side could be overloaded, even
though the total axle load is within the GVWR. It is important to redistribute the load to avoid
component failure, as well as to improve the handling characteristics of the trailer.

TIRES

All Jayco park trailers are equipped with name brand tires, designed and built for park trailers. Tires
are bias ply in design, offering excellent strength and mileage in various types of weather.
The air pressure should be maintained at its recommended pressure. Always check the tires when
they are cold, such as before traveling at the beginning of the day. It is normal for air pressure to
increase when traveling as tires will heat up. Do not release air pressure as tires become hot. If you
do, the tires will then be under-inflated when they cool down.
I
WARNING: It is recommended that the tire pressure be checked at the beginning of
each journey to obtain the maximum life of the tires. Underinflated tires may
overheat and fail or detach from the rims.
