Checking Tire Pressure
Note: Underinflated tires can decrease handling,
stopping performance, traction, tire life, and load-carrying
capability, in addition to causing other negative and
hazardous effects, including tire failure. Overinflated
tires are at greater risk of an impact break, where the
tread and casing break when striking a hard edge,
often opening a huge gash across the tread. Incorrect
inflation pressure also increases tires wear rate.
Therefore, it is important to keep tires inflated properly.
Check all tires’ pressure at least monthly,
due to the following factors:
• Most tires naturally lose air gradually.
• Tires can suddenly lose air if the tire
strikes a pothole, curb, or other object.
• It is usually not possible to determine
underinflation of radial tires by visual inspection.
This vehicle has 60 PSI recommended cold tire inflation
pressure. The term “cold” in this manual does not
refer to the temperature outside, but it refers to the
fact that a tire that has not been driven for a period is
cooler (and therefore has lower pressure) than a tire
that has been driven on. Tires heat up while being
driven on. To check (or fill to) a tire’s cold inflation,
the tire must have not been driven for more than a
mile or two for at least three hours. If you check a
tires pressure when it is not “cold”, the pressure will
appear higher than the actual cold tire inflation.
Steps for Maintaining Proper Tire Pressure
1. Locate the recommended tire pressure on the
vehicle’s tire information placard, certification
label, or in the owner’s manual. This Trailer has
60 PSI recommended cold tire inflation pressure.
2. Measure and record the tire pressure of all tires.
3. If the tire pressure is too high in any of the tires
and the tires have not been driven for at least
three hours, slowly release air by gently pressing
on the tire valve stem with the edge of your
tire gauge until you get to the correct pressure.
If the vehicle has been driven within the past three
hours and the tire pressure is too high on any tires,
then recheck the pressure once the tires have been
allowed to sit motionless for at least three hours.
4. If the tire pressure is too low, note the difference
between the measured tire pressure and the
correct tire pressure. These “missing” pounds
of pressure are what you will need to add.
5. At a service station, add the missing pounds of
air pressure to each tire that is underinflated.
6. Check all the tires to make sure they
have the same air pressure.
7. If the tires’ pressure was not measured “cold”,
then the pressure should be rechecked
with the tires cold as soon as possible.
Tire Size
To maintain safety, only purchase new tires of the same size as the original tires.
Look at the Tire and Loading Information Placard, the Specifications Chart in this manual, or the sidewall
of the tire being replaced. If you have any doubt about selecting the correct size, consult a tire dealer.
Tire Tread
The tire tread provides traction that prevents your vehicle from slipping, especially if the road is wet or icy.

Measure tread depth using a tread depth indicator (not included).
Tire Rotation
Every 5,000 miles the left and right tires should be switched.
This will cause the tires to wear more evenly and last longer.
Tire Balance and Alignment
The tires need to be balanced to prevent vibration when driving. This involves attaching small weights to the
rim to offset small differences in rim and tire weight. The tires also need to be aligned properly. Alignment is the
orientation of the tires to the road surface and their being parallel. This helps the tires to wear evenly, and provide
better traction. Both tire balance and alignment require specialized equipment that is not provided with this vehicle.
