The H727 is HankookÃ¢ÂÂs premium passenger touring all season tire. ItÃ¢ÂÂs so good that Hankook offers a 100K mileage warranty. In addition, Hankook offers a limited road hazard warranty. For the first 25% of tread wear, Hankook will warranty the tire if it is damaged due to a road hazard. This is a warranty not offered by many other manufacturers. If you are looking for a long lasting tire with a smooth ride, this may be the tire for you. This tire's price is slightly higher than Hankook's entry-level tire, however for only a small amount of money per tire more, you are buying a tire with a 100,000 mile warranty. It's a premium tire purchase for a budget minded consumer. Technically, the Optimo H727 integrates FSO (Footprint Shape Optimization), a computer calculated tread design to create a premium, touring, all season tire. This outstanding treadwear property contributes to the quiet, comfortable ride. With hundred's of sipes built into the tread design and four open grooves, this gives the driver the traction needed to handle all season conditions.
