MICHELIN TIRE LIMITED WARRANTY W A R R A N T Y On-the-wheel repairs or plug-only repairs should not be made. They may cause further tire damage because the repair may not be air-tight and/or the plug may fail. Storage Tires should be stored in a cool, dry place indoors so there is no danger of water collecting inside them. When tube-type tires are mounted with water trapped between the tire and the tube, liquid may pass through the inner liner and into the casing plies. This can result in sudden tire failure. Most problems of this nature are caused by improper storage that permits water to enter the casing between the tire and tube prior to mounting. Tires contain waxes and emollients to protect their outer surfaces from ozone cracking and weather cracking. 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. When tires sit outdoors unused for a month or more, their surfaces become dry and more susceptible to ozone cracking and weather cracking. That's why tires should always be stored in a cool, dry place away from sources of heat such as hot-water pipes and electric generators. Also, make sure that the surfaces on which tires are stored are free of grease, gasoline and other substances that could deteriorate rubber. Failure to store tires in accordance with these instructions could result in premature aging of the tires and sudden tire failure. 76 Y o u r W a r r a n t i e s i n D e t a i l
