I've had these tires on my car for the past 2.5 yrs and 20k miles. For the first 5k miles, they were remarkable- dead quiet, smooth, sticky, responsive. After that, there was a precipitous decline. They developed this pesky vibration which multiple RoadForce balances, alignments and rotations never cured. They then became noisier and developed this strange high-pitched hum. I thought my wheel bearings or suspension was at fault first, but turns out they all checked out fine. They also need to sufficiently warm up for a few miles regardless of temperature in the morning to get the flat spots out. Despite these issues, they are wearing okay and have 7/32 left all around. These tires were pretty cheap when I bought them so I guess you get what you pay for.
