  • Warranty


    American Pacific Industries, Inc. (API) hereby warrants that every new ST Radial Tire purchased from API bearing the brand name Zenna to be free from conditions of workmanship and material that would cause the tire to become unserviceable for the life of the original tread less 2/32” as measured in the fastest wearing groove. The life of the original usable tread ends when the tire tread has worn down to 2/32” remaining, at which point the tire is considered to be fully worn out. This warranty applies only to the original purchaser for a period of two (2) years from the date of manufacture. API’s liability under this warranty shall be limited to replacement and/or credit for the cost of the tire excluding FET.



    If any Zenna tire becomes unserviceable, API will do either of the following:

    A. If the tire becomes unserviceable due to material or workmanship during the first 2/32” of the

    original tread, API will replace such tire with a comparable new Zenna tire free of charge. Applicable taxes on the new tire and costs of mounting and balancing service shall be borne by the owner.

    B. If the tire becomes unserviceable due to material or workmanship after the first 2/32” of tread

    wear, a credit excluding FET will be given toward the purchase of a comparable new tire in proportion to the usable tread remaining as measured in the fastest wearing groove.  Applicable taxes on the new tire and costs of mounting and balancing service shall be borne by the owner.



    A.  All API warranties are limited to the original purchaser and the original vehicle on which they are mounted and are not assignable to subsequent purchasers or vehicles.

    B.  This limited warranty is applicable only in the United States and Canada and any tire used on a vehicle registered or operated outside of these areas is not covered by this warranty.

    C.  The following is not covered by the Limited Warranty:

    1.  Tires branded or marked “Non-Adjustable” (N/A) or “Blemished” (Blem), or previously adjusted.

    2.  Tires that are deemed out-of-round or out-of-balance

    3.  Failure, damage or irregular wear due to:

    a.  Road hazards (i.e. puncture, cut, snag, impact breaks, etc.);

    b.  Fire, accident or vandalism;

    c.  Mechanical condition of vehicle, including improper alignment, improper inflation, wheel imbalance, faulty shocks or brakes;

    d.  Misapplication of the tire, use of improper inner tube;

    e.  Alteration of the tire or addition of foreign material or transfer from one vehicle to another;

    4.  Cost of service, mounting and dismounting.

    5.  Loss of time or use, inconvenience, or any incidental or consequential damages of any type or nature.



    In order to be eligible for Limited Warranty Service, the owner must:

    A.  Present the tire to an authorized dealer;

    B.  Present proof of purchase to the satisfaction of the dealer;

    C.  Complete and sign an API Warranty Claim Form, which is available from any authorized dealer;

    D. Pay the amount due on a new tire, less the amount of credit, including taxes, mounting and balancing charges or cost of other services ordered.
