Since I purchased the tires on ~Oct 16, 2015, my car vibrates when I brake at high speeds. I think maybe the technician used too much torque and warped the rotors a little. I've been buying tires from Colonial for many years, and this is the first time this has happened. Recently (July 23, 2016), after they rotated and balanced the tires, I found two loose hubcaps and one balancing weight on the ground when I parked the car at home. This is not the first time I have found loose hubcaps after tire rotation. Before my current set of new tires, I have lost 2 hubcaps 1-2 weeks after having my tires rotated by Colonial Tire.
