I bought a 2006 Commander and need a new set of tires. Well my spare was a brand new GoodYear Fortera so I was just going to buy 3 new ones and use one of the old tires as a spare. I did some research and found that there are two types of the Fortera 105S that I have on my Jeep. One has white wall and one doesn't. The ones I have are white walled but I wanted to know if I could flip them around so that the black walls show and the letters are on the inside of the vehicle. PLEASE HELP!!
