What is not covered by the manufacture's warranty:
Road Hazards such as nails, glass, rocks, cuts, snags, punctures, scuffs, vandalism, chemical corrosion, accident, or other foreign objects.
Damage or failure caused by, resulting from, or arising out of improper operation or maintenance such as, without limitation, misapplication, neglect, misuse, improper mounting or dismounting, use of puncture sealants, or any alteration or decorative material to the tire, without limitations, to the tread or sidewall.
Adding sealants to Maxxis UST tubeless tires voids the warranty.
