A piece of metal went through the inside wall of my 285 tire. While I was at the dealer today to get a new tire the rep told me that the tire that comes stock in our H3 is discontinued so I had to get a totally different tire tred and side wall from my 4 stock tires. I bought a tire cover to hid the different tire. I didn't question him when he told me the tire was discontinued but it bothered me later on while I was home that the tires didn't match, so I called the dealer to confirm it was really discontinued or was he just trying to sell the tire that he had in stock and he guarenteed me that it was discontinued. Is this true?
