After 45,000 miles I could not be happier. Still have plenty of tread and the ride is as if the tires are new. Dropped the gas mileage a bit from the previous Dunlop's that were oem, but that was also because they were like q-balls with no resistance and consequently no tread to absord the noise and shock either. The popularity of these tires has also led to a price increase.....as well as the cost of materials......but I would not hesitate to buy another set based on this experience. By the look of things, I may get 70,000 plus, not bad for a truck tire.
