Sutong Tire Resources, Inc. (STR) hereby warrants that every new Synergy MTR tire purchased under this limited warranty from an authorized dealer of STR is free from defects in workmanship and material for the life of the original tread, down to 2/32”, at which point the tire is legally worn out.


If a defect in workmanship and materials is found in any Synergy MTR tire within the first 50% of tread wear (calculated by subtracting one-half (1/2) the difference between the original new tire depth and 2/32” from the original new tire tread depth), STR, Inc. will refund the cost of a replacement of the tire as follows:

  1. The defective tire must be replaced with a comparable new Synergy tire by an authorized dealer. Proof of replacement will be required.
  2. Applicable taxes on the new tire shall be borne by the owner.
  3. 50% free replacement applies to new first quality tires only. Blemished (Blems), retreads and road hazard tires are specifically excluded.


If a defect in workmanship and materials is found in any Synergy MTR tires after the first 50% of tread wear of the original usable tread has worn out, a credit will be given toward the purchase of a comparable new Synergy tire in proportion of the original usable tread remaining on such defective tire to the original usable tread of the new tire. Applicable taxes on the new tire and costs of mounting and balancing service are the responsibility of the owner. Adjustment on out-of-balance or out-of-round tires is allowed only during the first 2/32” of the original tread.


  1. The casing of truck tires is warranted against defects in workmanship and materials through the life of the second retread. The life of the second retread is considered to end when the remaining tread on the second retread reaches a buffing stage of 2/32” or less.
  2. Casing warranties are valid only for the first five (5) years after the date the original tire was manufactured.
  3. If an examination shows that a casing of a radial truck failed to such a defect, STR will issue a credit toward the purchase price of a comparable new Synergy tire in amount indicated below:
    All 17.5-inch rim sizes $20.00
    All 19.5-inch rim sizes $20.00
    255/70R22.5 275/70R22.5 $40.00
    11R & 295/75R22.5 $60.00
    11R & 285/75R24.5 $65.00
    315 & 385 & 425R22.5 $70.00


  1. STR limited warranties only extend to the original purchaser and the original vehicle on which they were mounted and are not assignable to subsequent purchasers or vehicles. Warranties only apply for two years from the date of purchase.
    This limited warranty is applicable in the United States and Canada only. Tires used or equipped on a vehicle registered or operated outside the United States and Canada are not covered by this warranty.
  2. The following is not covered by this limited warranty:
    1. Tires branded or marked “Non-Adjustable” (N/A) or “Blemished” (Blem) or previously adjusted tires.
    2. Failure, damage, or irregular wear due to:
      1. Road hazards (i.e., puncture, cut, snag, impact breaks, etc.) and/or collision damage.
      2. Fire, accident, vandalism, improper alignment, wheel imbalance, faulty shocks, or brakes.
      3. Misapplication of tire or use of an improper inner tube.
      4. Alteration of the tire or addition of foreign material, including chemical balancing materials.
    3. Cost of mounting and balancing service.
    4. Loss of time or use, inconvenience, or any incidental or consequential damage.


To be eligible for limited warranty service, the owner must:

  1. Present the defective tire to an authorized STR dealer from which the original purchase was made.
  2. Present proof of purchase to the satisfaction of the dealer.
  3. Complete and sign a STR claim form, available at any STR, Inc. authorized dealer.
  4. All claims must be made within 30 days of the defect discovery or tire failure.
  5. Sutong reserves the right to inspect the tire before making any adjustment.
  6. 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.


This limited warranty, or any warranty stated or referred to herein, is exclusive and in lieu of any other warranty regarding the quality of Synergy MTR tires. No employee of Sutong or its dealers and, or representatives have the authority to make representations other than what is stated herein, whether expressed or implied, and remedies for breach thereof shall be limited to those specifically provided herein.
