I had these bridgestone tires new with a new vehicle purchase. I, as always keep up with tire rotation and alignment, oil changes ect. With a little under 20K miles, just prior to my next rotation I took the tires back to the dealer due to the wear. All four tires had worn down considerably, to the point of being unsafe. I was asked to provide proof of rotations, which I did. When the dealer contacted Bridgestone, they refused to honor the warranty claiming that well I could have hit a pothole or the alignment must be bad. This was nothing more then an excuse to refuse to honor the warranty. Needless to say I bought tires elsewhere and will never buy Bridgestone tires again.
