Kumho Crugen HT51 Tire

I. What is covered by the warranty and how long?

Kumho Tire U.S.A. Inc, 133 Peachtree Street, NE Suite 2800 Atlanta, GA 30303, warrants to the original consumer purchaser that all KUMHO replacement radial tires either directly or through an authorized KUMHO dealer, and which are mounted on cars within the U.S.A., and becomes unserviceable for any reason within the manufacturers control, such tire will be replaced with an equivalent KUMHO tire. 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:

A. 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.
B. 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%
C. 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. Applicable taxes and costs of mounting and balancing and any other service charges are payable by the owner.
D. 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.
