Changing A Tire; Tire Grip; Hydroplaning - Airstream Interstate 2019 Owner's Manual

Always replace wheel nuts that are damaged
or rusted. Never apply oil or grease to wheel
nuts. Damaged wheel hub threads should be
repaired immediately. Incorrect mounting bolts
or improperly tightened mounting bolts can
cause the wheel to come off. This could cause an
accident. Make sure to use the correct mounting
bolts. Check tightness of wheel nuts regularly and
retighten if necessary.

Tire Grip

Tire grip is greatly reduced on a wet or icy road� Speed
and driving style must therefore be adapted to suit road
conditions� In winter, install M + S radial tires� Below
a tread depth of 1/8 in�, tire grip begins to decrease
rapidly on wet roads�
NOTE
California Tire Chain notice: Your motorhome may
not be operated with tire chains.

Hydroplaning

Depending on the depth of the water layer on the road,
hydroplaning may occur, even at low speeds and with
new tires� Reduce vehicle speed, avoid grooves in the
road, and apply brakes cautiously in the rain�
The majority of flood-related deaths are caused by
people attempting to drive through moving water�
Driving into flood waters may be the most dangerous
thing one might ever try� Considering the following:
• Most cars will float (and be swept away) in 18-24
inches of moving water� Trucks and SUVs have only
6-12 more inches of clearance� Creeks and rivers
can rise very rapidly and the road bottom can also
wash away, making the water much deeper than it
appears�
• Once cars are swept downstream, they will often roll
to one side or perhaps flip over entirely. The driver
has a few seconds to escape the vehicle� Many
drivers panic as soon as the vehicle submerges and
are found later with their seat belt intact�

WARNING

Changing A Tire

(Partially excerpted from the Mercedes-Benz Sprinter
Van Operator's Manual)
After changing a wheel, the wheel nuts must be
tightened once the vehicle has been driven for about
30 miles�
If new or repainted wheels are fitted, the wheel nuts
must be retighten again after about 600 to 3000 miles�
Do not use remolded tires�
Fitting wheel sizes other than those supplied by
Sprinter to the vehicle will change the Sprinter's
handling characteristics and may lead to an
accident resulting in severe personal injuries,
death and property damage.
NOTE
Read the Sprinter manual for wheel torque and
wheel tightening procedures.
The Mercedes-Benz Sprinter Operator's
Manual contains important cautions, warnings,
specifications, and operational information on
changing, maintaining, and replacing of the tires
and wheels. Read, understand, and follow the
Sprinter manual sections for changing a tire.
CAUTION
Changing a tire on a touring coach chassis is
a physically demanding procedure. It requires
specialized tools and knowledge of safety
procedures. Only you can determine your
knowledge base and physical ability. Don't take any
unnecessary risks. Find a safe area to park your
unit, and call a tire service center and supply them
with the information in the Sprinter Manual if you
have any doubts about changing a tire.
