Ok so I'm now going back to see if I can solve this problem. I tried the cement and the right front wheel is the only one that suffered the damage so my next thought is to try ridge tile bonding cement. This stuff is extremely tough and claimed to be flexible so I am going to give it a try and see if it will do the job. I think there is a good possibility it will work fine. Still fill the cavity with styrene beads and a coating of the bonding cement over the top. Then I will have to find some pretty rugged grass area to mow to see how it stacks up. Once the wheels have been used cutting grass they look just like any other second hand Victa wheel with the grass on them.
