Underinflated Tires
Underinflation brings a higher risk of damage due to
road hazards, reduce casing durability, cause a loss in
fuel economy, and will result in uneven or irregular tire
wear. Severe underinflation brings about an increased
risk of tread separation, handling difficulties, and
possible tire failure, caused by overheating.
When minimum inflation pressure requirements are not
met, tire durability and optimum operating conditions
are compromised. Tire inflation pressure should always
meet the guidelines for vehicle weight.
Observe the following:
• It may be necessary to inflate your tires at a truck
stop or truck service center in order to achieve
adequate air pressure for your trailer’s needs.
• Only permanent air seal metal valve caps should be
used.
• Be safe - if a tire has been run in a 20% underinflated
condition, it must be dismounted and inspected by a
trained professional. It should not be aired up without
a full inspection or without using a safety cage. Use
a calibrated gauge. If your tire is rated for higher
inflation pressures, a special gauge will be required
designed for larger tires.
• Do not bleed air from warm tires to reduce pressure
buildup.
• Do not inflate tires to cold PSI rating beyond rim
specifications.
How Overloading Affects Your Tires
Tire pressure is what enables your trailer tire to
support loads, thus, overloading can have serious
consequences. Too much weight can cause stress
on the suspension system components, brake failure,
handling and steering problems, irregular tire wear,
and possible tire failure. If you discover that your tires
cannot handle the load, lighten the weight of the load
on your tires.
Weighing Your Trailer Or Towed Vehicle
Since a trailer or towed vehicle adds to the load on the
tires, it is crucial to properly weigh towed vehicles; see
Loading on page 7-3 and see Weighing Your Trailer
on page 7-4�
Tire Care
The most important function of tires are to provide
traction while moving, and grip when steering or
stopping. The tires on your trailer are designed for
highway use and must be properly maintained in order
to maximize tire life, as well to provide a safe mode of
transportation.
Tire Care Tips
To reduce the risk of tire failure, we strongly
recommend the following:
1� Check the pressure in your tires, including your
spare, at least monthly when the tires are cool
(after the vehicle has stopped three hours and then
driven less than one mile). Do not reduce pressure
when tires are hot. Use a tire gauge to check
pressure and maintain it at the recommended level.
2� Never overload your tires. Heed the maximum
load-carrying capability of your tires.
3� Check your tires frequently for scrapes, bulges,
separations, cuts, or snags resulting from use. See
your tire dealer immediately if any such condition is
discovered.
4� Never operate your vehicle in excess of lawful
speeds or the maximum speeds justified by driving
conditions, or in excess of speeds recommended
for the tires you are using.
5� Make every effort to avoid running over objects
that may damage the tire through impact or cutting,
such as chuck holes, glass, metal, etc.
6� Never drive on smooth tires. Tires should be
removed when 2/32 in. of tread depth remains. In
most states it is illegal to drive with less than 2/32
in. remaining tread depth.
7� Park out of the sun whenever possible when in
warm climates. In desert regions, use tire covers to
prevent ultra violet light deterioration to tires.
