Kenda LoadStar trailer tires carry a warranty that is 2nd to none. They have confidence in the quality of the tires they produce, and are equally confident in the strength or their warranty. LoadStar's warranty covers tires that are four (4) years from date of manufacture or two (2) years from date of purchase, whichever comes first. To make the process as convenient as possible they put the Warranty department's 800-number (1-800-225-4714) on the side wall of every tire they make; the end user can call LoadStar directly if they have a problem or question about their tire.
