I purchased four brand new tires from Kauffman Tires December 2018, it is September 2019 and tores are bad and must be replaced. I was told it was a maintenance issue and the warranty I purchased would not cover the new set of tires. They want to charge me more tgan what I paid for the 1st set 9 months ago. The tires thread is worn on the front tires and warped on the vack. I am so frustrated what do I do? Need new tires. I feel cheated!!!!
