Should any tire manufactured by Kumho Tire Co., Inc. covered by this warranty become unserviceable due to a material or workmanship condition during its useable tread life (more than 2/32" remaining tread) before 6 years from the date of manufacture or purchase date supported with proof of purchase for every passenger and light truck tire (whichever comes first), and before 5 years (6 years for KLS02e, KLD01e, and KLT02e patterns) from the date of manufacture or purchase date for commercial truck tires (whichever comes first), KUMHO will do either of the following:
During the first 2/32" of the original usable tread, Kumho will replace such tire with a comparable new KUMHO or Marshal tire free of charge. Applicable taxes on the new tire and costs of mounting and balancing and any other service charges are payable by the owner.
After the first 2/32" of the original usable tread, a credit percentage will be given toward the purchase price of a comparable new Kumho or Marshal tire effective at the time of adjustment. Applicable taxes on the new tire and costs of mounting and balancing service are payable by the owner.
To obtain the credit percentage, please refer to Adjustment Credit Percentage Table or utilize the following example:
R.T.D.: Remaining Tread Depth
O.T.D.: Original Tread Depth
If R.T.D. = 5 and O.T.D. = 10, the calculation is (5 – 2 : remaining usable tread depth) ÷ (10 – 2 : original useable tread depth) = 38%
Temporary Spare Tire
During the first 1/32" of the original usable tread, Kumho will replace such temporary tire with a comparable new Kumho temporary tire free of charge. After the first 1/32" of the original usable tread, but less than 2/32", a credit of 50% towards a comparable new Kumho temporary tire will be given.

Adjustment on ride complaint or out-of-round is allowed only during the first 2/32" of the original tread depth, and a max of 2 tire can be adjusted per vehicle.
The authorized KUMHO or Marshal dealer will determine the adjustment cost by multiplying the percentage of the original usable tread worn by the current KUMHO or Marshal dealer’s price list in effect at the time of adjustment.

Tires purchased from unauthorized KUMHO dealers do not qualify for the KUMHO Replacement Equipment Warranty. It is impossible for us to verify that these tires were stored properly, mounted correctly, or originally intended for sale in the United States. For this reason, KUMHO cannot guarantee the safety or quality of the products purchased from unauthorized marketplace.
As a consumer, you should only purchase KUMHO products from an authorized KUMHO Dealer in order to ensure that the manufacturer’s warranty is preserved. Please see the Dealer Locator on our website to find an authorized KUMHO dealer near you.
Replacement of two tires: Kumho Tire recommends replacing all four tires at the same time. However, when only two tires are replaced, the new tires should be put on the rear. The newer tires, with deeper tread, may provide better grip and water evacuation in wet driving conditions.
Mixing tire manufacturers or models can cause the vehicle to ride differently, depending on the location of the tire.
When replacing existing tires, note that different categories like Performance, Touring and Grand Touring have their own characteristics and are not designed to perform the same.
Changing performance categories and/or performance ranges can change the way the vehicle performs and can increase noise, harshness, and vibrations (NHV). You should NOT have tires installed that do not meet the requirements of the vehicle.
