NOISY, NOISY TIRES! HORRIBLE, STIFF RIDE. These tires cause my BMW 325i to feel like a barn wagon and to have a loud humming noise that sounds like a prop airplane engine. This car WAS fun to drive BEFORE I put these tires on it, but now with these tires, I have to blast the radio to compete with the noise from these tires on the highway. Please note that I only replaced my rear tires, so there are only two of these tires on my car and the ride comfort has plummeted dramatically. I can only imagine how unbearable it would be to have all four of the tires as the Kumho Ecsta 4X. I am very disappointed because most of the reviewers had reported that these were quiet tires, but that is not the case for my car. Now my car feels like a very low end vehicle on its last legs. Awful. Don't buy these tires. Or wear earplugs while driving that you would wear at a rock concert.
Despite my displeasure with the tires, I must say is that the service from TireRack has been excellent. The tires arrived when promised and the installer honored the prices agreed upon. I would definitely purchase tires from this website again, but they would be a different brand and model.
