I had to replace the top of the chopping block as it had worn completely through, I add a couple of extra layers of plywood to the top.
The other problem was the tire was not tall enough, and would tend to move around and fall off.
I screwed the tire to some pieces of 4"x4", and built a skirt around them to keep everything in place on the chopping block. Should work much better now.
