2007 Jeep Wrangler Tires

This is a great tire. It rides quite and I have gotten great wear. I am on my third set of 325 50 R22 mounted on my 2007 Dodge Ram 1500 4X4 with 3" lift. The problem I have is that I ran over a metal spike which went through the sidewall and have been trying to find a replacement. Apparently Yokohama is no longer making this size.
