I was told tread separation was issue. This dealer put my family at Risk! When the car went in for shaking they said the tire was defective. They replaced it and charged me $214, the tire only cost $150 new. I asked if the other tires were OK, the girl I paid said "the bad tire was from a different batch than the three remaining tires and they were OK." 2 weeks later 2 more tires go bad, putting us back in the car with defective tires put my family at risk. This dealer is dishonest and Dangerous. They charged me for 4 new tires total cost $492.35 when the set only cost $600 new and we only received 15% of the use...
