Proper Tire Ination
The level of air in your tires affects your vehicle’s
overall performance. Not even the highest quality tire
will perform well if it’s not inated properly. The correct
pressure varies from vehicle to vehicle and depends
in part upon driver preference� Each vehicle has a
recommended ination pressure, usually found on a
placard� Check the Sprinter manual for all weights and
tire information and the placard location�
Correct tire ination is a key component in tire care.
The recommended ination pressures for your tires
are indicated on the certication label or in your
owner’s manual� Since touring coach’s can be loaded
with many different congurations, the load on each
tire will vary� For this reason, air pressure should be
checked based on the load on each individual tire�
Cold Ination Pressure should be adjusted to handle
the maximum tire load, and all tires on the axle
should carry the same ination pressure. COLD TIRE
INFLATION PRESSURE is the tire pressure checked in
the morning before you drive more than a few miles or
before rising ambient temperatures or the sun’s radiant
heat affect it� Check your tire air pressure at least once
a month, before each trip, and each morning you drive
during a trip� Tire pressure should be checked cold, as
tire pressure ratings have been designed with typical
running heat/pressure build up in mind� Make sure the
valves and caps are free of dirt and moisture�
Under Ination
Under ination brings a higher risk of susceptibility
to damage due to road hazards, reduces tire casing
durability, and causes a loss in fuel economy, plus
uneven or irregular tire wear. Severe under ination
brings about an increased risk of tread separation,
handling difculties, and possibly tire failure, which is
caused by overheating�
NOTE
It is a common practice for motorhome owners to
lower tire pressure in their search for a smoother
ride. This is not only dangerous, it is relatively
ineffective, and the difference in ride quality is
not signicant. When minimum ination pressure
requirements are not met, tire durability and
optimum operating conditions are compromised.
Tire ination pressure should always meet at least
the minimum guidelines for vehicle weight.
• It may be necessary to inate your tires at a truck
stop or truck service center in order to achieve
adequate air pressure for your coach’s needs
• Only permanent air seal metal valve caps should be
used�
• Be safe - if a tire has been run 20 percent under
inated, it must be dismounted and inspected by a
trained professional. It should not be inated without
a full inspection or without using a safety cage� Use
a calibrated gauge� If your tire is rated for higher
ination pressures, a special gauge designed for
larger tires will be required.
• Don’t bleed air from warm tires to reduce pressure
buildup�
• Don’t inate tires to cold psi rating beyond rim
specications.
How Overloading Affects Your Tires
Tire pressure is what enables your touring coach tire to
support loads� Overloading your tires can have serious
consequences for passengers and your touring coach.
Too much weight can cause stress on your touring
coach’s suspension system, brake failure, shock
absorber damage, handling and steering problems,
irregular tire wear and possible tire failure� Excessive
loads or under ination can lead to an excessive
amount of heat and tire failure� If you discover that your
tires cannot handle the load, lighten the weight of the
load on your tires�
Tires and Wheels
(This section is partially excerpted from the Sprinter
Van Operator’s Manual�)
Check tires regularly for even tread wear, tread depth
(note legal requirements), and signs of external
damage� Use only wheels and tires of the same size,
make, and pattern�
Do not install tires that are not approved for the size
and type of wheel installed on the vehicle itself� Only
use those wheel sizes that were delivered to you by
your authorized Sprinter dealer�
Use only wheels and tires that have been tested and
approved by the vehicle manufacturer�
Break in the tires at moderate speeds for distance of
about 65 miles�
