      Goodyear Dunlop trailer tires produced for the Europe, Middle East and Africa market under the brands Goodyear, Dunlop, Fulda, Sava and Kelly carry the “FRT” marking on their sidewalls. “FRT” stands for “Free Rolling Tire” and is a legal marking according to the UNECE Regulation No. 54, which indicates that the tire is specifically designed and intended for the equipment of trailer axles and axles of motor vehicles other than front steering and all drive axles.

      Therefore those trailer tires marked “FRT” should be used exclusively on trailer axles and should not be fitted in any other position Goodyear Dunlop will not warrant and cannot be held accountable for any potential liability claim involving FRT tires fitted outside these recommendations.
