The technological and market changes in the OTR tire industry presently and over the next five years are presenting several challenges to manufacturers and suppliers alike. Some of these challenges originate in one or more end-use market as a result of underlying market growth; or in the nature of OTR equipment or the manner in which OTR tires are used; or in technological changes in the tire or related industries; in the supply chain; or in the political and regulatory environments. Off-the-road tires or, OTR tires, are being built for the purpose of taking a massive amount of weight & roll through the conditions which would stop most of the cars dead.
