We are the original owners of a 2012 vw passat with hankook optimo h426 tires. the optimo h426 tires that came installed when we purchased the car. according to the manufacturers website the tires have a manufacturer warranty of 60,000 miles. see link below. http://www.hankooktireusa.com/serv/warranty.aspx?pagenum=3&subnum=1&childnum=1 hankook warranty department is refusing to honor the mileage warranty on the tires because the tires came with the vehicle. they state that the product only has warranty when purchased through a tire shop. my limited warranty pamphlet that came with my car does not state that the mileage warranty on the product does not apply. a copy of the warranty can be found at the link below. http://hankooktireusa.com/serv/originalequip.aspx?pagenum=3&subnum=1&childnum=2 i look forward to your prompt response in assisting to resolve this issue as my tires are worn below the 2/32nds inch and this poses a safety issue for my family and i.
