2009 Ford Focus Tires

had them on less than 2000 miles, and two sidewalls blew out, before that, i thought my brakes were going bad in the front, it was the tires, these junk tires were less than six months on my car, i went and paid for two different ones for the front after one sidewall blew, im waiting to get the two back ones changed, because i wasted my money on these junk tires.
