I never heard of Hankook tires before reading reviews of them on this site. The survey ratings and the comments on the Optimo H727 were very convincing. I have only driven about 100 miles on them but, so far, I think these are the best tires I've ever owned. They are very quiet and deliver a smooth ride. I have driven them on dry roads and through one torrential rain storm. Handling is excellent on dry and wet road conditions. Central Illinois gets it's fair share of winter snow and ice and I will be curious how well these tires do cutting through snow and over packed ice. I will report back on those conditions.
The OE tires on this van were Bridgestone Turanza EL42. They lasted 35,000 miles. I've never gotten more than about 30K miles on any set of tires so I'll be interested in how the tread wear on these Hankooks hold up.
