Tire Care
The most important function of tires is to provide
traction while moving and grip when steering or
stopping� The tires on your touring coach are designed
for highway use and must be properly maintained
to maximize tire life and provide a safe mode of
transportation�
For tire size, inflation pressure, and load ratings, see
Specifications on page 4-3 � For additional information
on tire care, inflation procedures, maintenance, and tire
handling, see Tires on page 7-3� Also see your Ram
Promaster Owner’s manual and review all tire care and
tire safety Information�
WARNING
For safety reasons, lug nut torque must be checked
immediately after changing a tire and again after
25 miles to 145 ft-lbs. The wheels could otherwise
come loose.
Tire Care Tips
To reduce the risk of tire failure:
• Check the pressure in your tires, including your
spare (not provided with vehicle), at least monthly
when the tires are cool (after the vehicle has been
stopped for 3 hours and then driven less than 1
mi)� Do not reduce pressure when tires are hot�
Use a tire gauge to check pressure and maintain it
at the proper level�
• Never overload your tires� Heed the maximum
load-carrying capability of your tires�
• Never operate your vehicle in excess of lawful
speeds, the maximum speeds justified by driving
conditions, or in excess of speeds recommended
for the tires you are using�
• Make every effort to avoid running over objects
that may damage the tire through impact or cutting,
such as chuck holes, glass, metal, etc�
• 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�
• Park out of the sun whenever possible when in
warm climates� In desert regions, use tire covers to
prevent ultra violet light deterioration�
Tire Inspection and Storage
Before taking your touring coach on a trip, inspect
tires and wheel rims for any condition or damage that
might result in tire failure� Inspect the front and back of
sidewalls, tread area, valve stems, valve stem caps,
and wheel rims for the following:
• Sidewalls for bulges, cracking, punctures, cuts,
abrasions, and foreign objects (nails/screws)�
• Tread for foreign objects, irregular/uneven wear,
bulges, cracking, punctures, and cuts� An uneven
wear pattern can indicate misalignment or worn
suspension parts�
• Check that tread depth remains above at least 2/32
inch� Tread depth gauges are available at most
automotive parts stores�
• Wheel rims for missing wheel weights, bead or
flange damage from curb strikes, and overall
general condition�
WARNING
Due to RISK OF EXPLOSION damaged tires or
tires run with more than a 20% underinflation
(approximate) must be dismounted, inspected by
a trained professional, and should not be inflated
without using a safety cage.
Since many touring coaches see infrequent seasonal
use, tires may take years to wear out� Tires will
age and deteriorate over time so they may require
replacement even if tread depth is optimal� Tires
with any of the conditions listed above may require
replacement� If you are unsure, consult a tire installer�
Any tire with tread depth less than 2/32 inches deep
should be replaced before your next trip�
Store your touring coach in a cool, dry area away
from major heat sources and extreme cold� An
enclosed storage area is best, with no exposure
to electromagnetic sources such as generators or
transformers� Cover your tires from direct sunlight if
you must keep your touring coach outside� Take your
touring coach to your tire dealer for service to check or
correct any of these conditions�
