These as you said, Randy, these Green Machines are made to be drift trikes or feel like drift trikes even on level ground going only moderate speeds.

Put these two together and you have a good repair. They use slices of pipe cut at the width of the wheel as covers since the back wheels are "consumable". Glue/tape/expanding foam the existing damaged wheel and then find pipe with correct inner dimension to slide over the whole thing (both sides)

That is probably a newer model,but the original Green Machine might well be considered C&V
