reason, tires should always be stored in a cool, dry, clean, indoor environment.
If storage is for one month or more, eliminate the weight from the tires by
raising the vehicle or by removing the tires from the vehicle. Failure to store
tires in accordance with these instructions could result in damage to your tires
or premature aging of the tires and sudden tire failure. When tires are stored,
be sure they are placed away from sources of heat and ozone such as hot pipes
and electric generators. Be sure that surfaces on which tires are stored are clean
and free from grease, gasoline or other substances which could deteriorate
the rubber. Tires exposed to these materials during storage or driving could be
subject to sudden failure.
One reason why your spare tire should be included in the tire rotation schedule
is that temperatures in a vehicle’s closed trunk, especially in sunny geographical
areas, can become high enough so that, over a sustained period, they can cause
small cracks or other changes to the properties of a tire stored in the trunk. An
accumulation of such changes can weaken the tire and, especially if the tire is
not kept properly inated, make it unsafe to use when it is needed.
PROPER TIRE MOUNTING
Tire mounting can be dangerous and must be done by professionally trained
persons using proper tools and procedures as specied by the US Tire
Manufacturers Association (USTMA).
Your tires should be mounted on wheels that are the correct size and type and
are in good, clean condition. Wheels that are bent, chipped, rusted (steel wheels)
or corroded (alloy wheels) may cause tire damage. The inside of the tire must
be free from foreign material. Have your tire retailer check the wheels before
mounting new tires. Mismatched tires and rims can explode during mounting.
Also, mismatched tires and rims can result in dangerous tire failure on the road.
If a tire is mounted by error on the wrong-sized rim, do not remount it on
the proper rim – scrap it. It may have been damaged internally (which is not
externally visible) by having been dangerously stretched and could fail on the
highway, resulting in an accident.
Old valves may leak. When new tubeless tires are mounted, have new valves
of the correct type installed. Tubeless tires must be mounted only on wheels
designed for tubeless tires, i.e., wheels that have safety humps or ledges. Always
utilize valve caps capable of containing the tire’s ination, should the valve core
leak. The valve cap is the primary seal against air loss. Each tire and wheel
assembly should be balanced to ensure proper tire and vehicle performance and
to maintain tire warranty coverage. Tires and wheel assemblies that are not
balanced may cause steering difculties, a bumpy ride, and irregular tire wear.
SPECIAL MOUNTING INSTRUCTIONS FOR SELF-SUPPORTING
ZERO PRESSURE
™
(ZP) TIRES
ZP tires can be more difcult to mount than conventional tires. They should be
mounted and demounted only by a properly trained tire professional. ZP tires
can generate a tremendous amount of heat when run at low or zero pressure.
ALWAYS ALLOW A ZP TIRE TO COOL BEFORE ATTEMPTING TO HANDLE IT.
FAILURE TO DO SO COULD RESULT IN INJURY OR DEATH. Michelin
®
ZP tires are
tubeless tires designed to operate in emergency conditions at low or zero air
ination.
