Yes, CST tires could be offered with limited warranty on materials and workmanship during the first 50% of treadwear. Under the warranty, the tire will be replaced with same or new comparable CST tire at no charge during the first 50% of treadwear. Only the labor charges and taxes are required to be paid by the customer. After the first 50% of treadwear, as the limited warranty is for four years from the date of manufacture, if a tire is found unserviceable, the manufacturer will provide a prorated manufacturer credit on purchase of same or comparable new CST tire. Certain terms and conditions are required to be met to receive the warranty credit in this case.
