Tires and Wheels

(This section is partially excerpted from the Ram
ProMaster Van Owner's Manual�)
Examine tires for excessive tread wear and uneven
wear patterns� Check for stones, nails, glass, or other
objects lodged in the tread or sidewall� Inspect the
tread for cuts and cracks� Inspect sidewalls for cuts,
cracks, and bulges� Check the lug nut/bolt torque
for tightness. Check the tires for proper cold inflation
pressure� Use only wheels and tires of the same size,
make, load rating, 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 Ram ProMaster dealer� Use only
wheels and tires that have been tested and approved
by the vehicle manufacturer�
Break in the tires at moderate speeds for a distance of
about 65 miles�
Always replace lug nuts that are damaged or
rusted. Never apply oil or grease to lug 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 lug nuts regularly and retighten
if necessary.

Tire Grip

Tire grip decreases rapidly on wet or icy roads,
especially when the tread depth is below 1/8 inch�
Adjust speed and driving style to suit road conditions�
NOTE
California Tire Chain notice: Your motorhome may
not be operated with tire chains.

Hydroplaning

Hydroplaning may occur, even at low speeds and with
new tires, depending on the depth of the water layer on
the road� Reduce vehicle speed, avoid grooves in the
road, and apply brakes cautiously in the rain�

Flooded Roads

Most flood-related deaths happen when attempting to
drive through moving water. 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 rapidly, and the road bottom
can also wash away� When these conditions occur,
water may be much deeper than it appears� Vehicles
often roll to one side or flip over entirely when swept
downstream, limiting the time necessary to escape�
