If damage exceeds these guidelines, the tire must be replaced.
Plug-only repairs done on-the-wheel are considered improper
and are therefore, not recommended. Such repairs are not
reliable and may cause further damage to the tire.
STORAGE
Tires contain waxes and emollients to protect their outer
surfaces from ozone and weather checking. As the tire rolls and
flexes, the waxes and emollients continually migrate to the
surface, replenishing this protection throughout the normal use
of the tire. Consequently, when tires sit outdoors, unused for
long periods of time (a month or more) their surfaces become
dry and more susceptible to ozone and weather checking, and
the casing becomes susceptible to flat spotting.
For this 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 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 the surfaces on which tires are stored are
clean and free from grease, gasoline, and other substances
which could deteriorate the rubber. (Tires exposed to these
materials during storage or driving could be subject to
sudden failure.)
FOLLOW THESE MOUNTING RECOMMENDATIONS
Tire changing can be dangerous and must be done by profes-
sionally trained persons using proper tools and procedures as
specified by the RMA.
Your tires should be mounted on wheels of the correct size
and type which are in good, clean condition. Bent, chipped or
rusted 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 in 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.
