Tires constantly suffer from cupping.
Back in september of 2012 was told i needed a new tire (bubble in tire) at only 15,000 miles. replaced tire at 208.00 dollars. july of 2013 had my 20,000 mileage service and was told another tire had a bubble and needed new tire. new tire purchased at 208.00 and also had my inspection sticker done at the same time;all tires passed inspection. on my way home from this service noticed my car was riding rough and a vibrating noise. brought the car back at dealership (all services listed done at fathers & son) two weeks after my july new tire purchase and was told i needed two more new tires, same problem bubbles inside and outside tires. had no choice because of safety reasons and had to purchase two more new tires for a total of 416.00 dollars. i have owned numerous cars and have never had to replace any tires even though i keep my cars for at least five years, but low mileage. i was told it was my driving habits so i decided to go on the internet to research these tires and was appalled on how many complaints and unsatisfied consumers with almost all the same problem i had. please check into these tires as to my knowledge are very unsafe and could cause a serious accident if these tires rupture because of the bubbles. to this date i had to replace all four tires with current mileage of 22,668.
