This limited warranty/adjustment policy provides for tire replacement under certain specified conditions. This policy applies to tires used in normal highway service displaying warrantable conditions. Tires that become unserviceable or wear out because of neglect or mistreatment are excluded from Yokohama warranty coverage. The tire size, load range and speed rating must meet or exceed the specification recommended by the vehicle manufacturer.
This warranty applies to every Yokohama truck/bus and light truck commercial (LTC) tire bearing the Yokohama brand name and complete D.O.T. serial identification number and operated in normal highway use in the United States. Eligible tires must be on the vehicle on which they were originally installed, in conformance with the vehicle manufacturer’s recommendations. This warranty applies only to the original tire purchaser, and is not transferable to any other party. Tires are covered by this warranty for the life of the original usable tread down to the tread depth indicators molded at 2/32” (1.6mm). The tread is worn out when those indicators are at the same level as the worn tread.
Tires that have become unserviceable for the following reasons:
• Road hazard injuries or damage caused to the tire by obstacles and debris, such as cuts, punctures (whether repairable or not), snags, bruises, tears or impact breaks.
• Improper repairs or repairs that have failed.
• Improper inflation or other maintenance abuses.
• Improper application of tire size and/or specification.
• Improper mounting/dismounting procedures or tire/ wheel assembly balance.
• Mechanical irregularities in the vehicle or wheel, such as bent wheel assemblies, misalignment, worn or faulty components.
• Weather checking/cracking or failures resulting from these conditions on tires purchased more than four years (48 months) prior to a warranty claim. If proof of purchase is not provided, the D.O.T. serial number is used.
• Accident, corrosion, vandalism, fire or damages caused by nature.
• Tires that have had material added after leaving a Yokohama manufacturing plant, such as fillers, sealants, balancing substances or materials of any kind. Additionally, tires that have had external tire treatments which include but are not limited to: tread siping, shaving, carving, regrooving, white sidewall inlay or applying materials or treatments to the tread surface. If the material or treatment is the cause of a failure, vibration, or ride disturbance the tire will not be accepted for warranty, or mileage warranty credit.
• Tires submitted for ride disturbance complaints after 2/32” (1.6mm) of treadwear or 12 months from date of purchase, whichever occurs first.
• Tires on vehicles registered or operated outside of the United States. (Refer to applicable Yokohama warranty policies for country of operation.)
• Tires not sold in the United States by Yokohama Tire Corporation.
• Tires branded by Yokohama to note special classification at time of purchase, such as “NA” (non-adjustable) or tires altered by notching or buffing.
• Improper storage.
Tires that have become unserviceable for reasons other than stated above will be replaced in accordance with this warranty.
A Yokohama tire accepted for warranty credit during the first 2/32” (1.6mm) of treadwear or 12 months from date of purchase, whichever occurs first, due to a ride disturbance complaint only, will be replaced on a no-charge basis. During this wear period, tires will be mounted and balanced free of charge. Federal Excise Tax (FET) will not be collected on a no-charge adjustment. Other service charges, such as tire rotation and wheel alignment are payable by the customer.
For all other warrantable conditions, a Yokohama tire will be replaced on a pro-rated basis. The customer will receive credit toward the purchase of the new tire by multiplying the percentage of the tread depth remaining by the dealer’s current selling price of the new comparable Yokohama tire at the time of replacement service. The customer pays full Federal Excise Tax (FET) applicable to the comparable new Yokohama tire plus all mounting, balancing and other service charges.
Replacements qualifying under the warranty must be made by an authorized Yokohama dealer.
The customer must present the claim tire to an authorized Yokohama dealer in the United States.
All implied warranties, including any warranty of merchantability or fitness for a particular purpose, are expressly limited to the duration of this written warranty.
All obligations or liabilities for loss of time, inconvenience, loss of vehicle use or any other incidental or consequential damages are hereby excluded. Some states do not allow limitations on how long an implied warranty lasts, or the exclusions or limitations of incidental or consequential damages, so the above limitations or exclusions may not apply. This warranty gives the customer legal rights that may vary from state to state. The customer is advised to determine those rights for his/her local area and exercise them as required or deemed appropriate.
This policy applies to tires displaying warrantable conditions when used in appropriate service as defined in the Yokohama Commercial Sales and Reference Guide and which meet the following criteria.
• Tires must be or have been retreaded by a Yokohama- approved retreading process. Please reference the approved retread list at www.yokohamatire.com.
• Tires must be or have been inspected by a Yokohama approved non-destructive tire casing analyzer prior to any retreading, and be so identified.
Truck tires designated by Yokohama as approved for and used in on/off highway applications are eligible for warranty consideration if they display warrantable conditions.
Prior to the retreading process, Yokohama radial truck/ bus tires are covered by all provisions of the Yokohama Standard Limited Warranty for Truck and Bus Tires. After the retread has been applied on the qualified tire, an additional special casing warranty applies. If a qualified tire becomes unserviceable due to a warrantable condition, the customer will be given a casing credit, as indicated in the chart below. The retread life is defined as beginning with the installation of the new retread stock and ending after buffing for subsequent retread.
• Casings retreaded more times than provided by the warranty statement in the chart.
• Casings damaged by road hazard injuries or damages caused by obstacles or debris such as cuts, punctures (whether repairable or not), snags, bruises, tears, abrasions, or impact breaks.
• Casings damaged by improper repairs or repairs that have failed.
• Casings damaged by improper inflation or other maintenance abuses.
• Casings damaged by continued operation while flat or severely underinflated.
• Casings damaged by improper application of tire size and/or specification.
• Casings damaged by improper mounting/dismounting procedures or tire/wheel assembly imbalance.
• Casings damaged by accident, corrosion, vandalism, fire, or nature.
• Casings damaged by use of aftermarket tire additives, such as fillers, sealants, or balancing substances.
• Casings damaged by improper retreading or defective retread materials.
• Casings that cannot be retreaded because of excessive treadwear or buffing.
• Casings retreaded in a facility not using a Yokohama approved retreading process.
• Tires covered by Yokohama Standard Limited Warranty (4/32” or more of original tread remaining).
• Tires branded by Yokohama to note special classifications at time of purchase, such as “NA” (non-adjustable), or tires altered by notching or buffing.
• Tires on vehicles registered or operated outside the United States. (Refer to applicable Yokohama warranty policies for country of operation.)
• Tires not sold in the United States by Yokohama Tire Corporation.
