those are the bias ply military tires and are 36" tall. They suck. Terrible pattern to them is instantly obvious they will and do pack up in mud. Better off with the 37" radial tires they used, they still pack but not half as bad, the ones they use right now are 37" BFG baja's and are a much softer pattern and look to be a great tire by the pattern, but since they have only been using them for a couple of years are not as easily available yet.
