Bought 4 Hankook v12 tires from here on Dec 8, 2014. After 1866 miles the driver's side rear tire, inside side-wall, separated from the tire. We took the tire back and the technician took a look at the tire and noted that there were no punctures and little to no wear on the tire. He noted that it "probably" a manufacturer's defect but couldn't be 100% certain that this didn't happen as the result of a road hazard. We then asked him to call Hankook and inquire as to the warranty status. He told us that he called and the OEM said that there was nothing they could do however when we asked for the contact information it took him 20 minutes to find it. Hmmmm, he said that he just called them. This seemed a little fishy. When we pressed the issue he said that he couldn't and wouldn't verify the information to the manufacturer because if Hankook made the decision to replace the tire under warranty, Porter tire would have to respond with a warranty replacement. This infuriated me. Porter's explanation for the refusal to repair was that we didn't purchase their road hazard warranty. We didn't have to as these tires are warrantied by the manufacturer. They then informed us that the warranty card was sent to the OEM and the tires weren't registered in a timely manner; excuses, excuses, excuses. As a side note, when we purchased a new tire (out of necessity) they still didn't offer the OEM's warranty card, even after just going through the issues that we had. Left befuddled and feeling like we were duped out of another $250. We took the tire to the next closest Hankook dealer and had them take a look and without batting an eye, the lead technician affirmed that this damage was a manufacturer defect. The other dealer even helped with returning the tire to Hankook and issuing a refund. This was top notch customer service and helped make this right. We will never again use Porter Tires of Morristown nor will we recommend their service station to any of our friends, family, or colleagues. I like supporting smaller, local businesses when and where I can, even if costs a little more than the big box stores however in this case, I would much rather drive the extra distance or take my business to a big box store.
