Purchase 4 Continental extreme contact tires (PK15-46-1960: 205/55R-16) on 1/12/2015. On Saturday 8/6/2016 around 5 pm the 2 tires on the passenger blew out at the side wall at the same time. Lucky my daughter was just pulling into a parking lot (witness say she didn't hit anything). No warning lights came on indicating a problem. Had to go to Firestone for replacement tires. Replaced the ones on driver side for I didn't trust them. File a warranty issue and even call Continental they to bad about the other 2 tires. I believe these tires have a defect for they have plenty of life left on them

Brake calipers and pistons were defected and wouldn't release after you released the brake. The wheels had to be moving for the brakes the be releases. Causing the the brake pads to grind down to nothing and have metal on metal contact. It was worse in the front then the back. I received all new brake calipers because they couldn't be fixed.
