Mine are wearing like a chunk of steel. They also ride like wagon wheels and sound like I have 4 bad wheel bearings. Maybe a little hyperbolic, but not by much. Add in a 10% loss in fuel economy and these will go down as the worst tire purchase I ever made. My alignment is dead on perfect, tire pressure and balance are exact, they wore to 8/32nds pretty quick and now just live there. Mile after mile. I’ve had them balanced on a hunter as well as road force balanced and still deal with an 80mph vibration. I absolutely despise these tires! I see that they’re coming out with a cc3 and you can count me out. My local tire shop said they’ve had similar complaints and no longer recommend them. I’m glad they work for some folks, but coming from primacy’s there’s no comparison.
