The Eco-Trail ST combines sensibility with performance of an ST tire with a truly revolutionary tread design that gives the appearance and footprint similar to that of a radial tire.

Features & Benefits

The Eco-Trail ST Bias is designed with a truly revolutionary tread design that gives the appearance and footprint similar to that of a radial tire. An engineered compliance to RoHS Regulation that limits or eliminates hazardous substances dangerous to the environment and to people, the Eco-Trail ST combines sensibility with performance under the high loads and rigorous demands of an ST tire.

  • Modern tread design
  • Reinforced square shoulder tread for optimum road contact
  • RoHS Compliance (reduction or elimination of mercury, hexavalent chromium, lead, cadmium, PBB and PBDE) for rubber compounding
  • Variable tread pitch for reduced road noise
