Rims for RC Tractors?

[rc_farmer]

I had an extension shaft made for my and Pauls steiger. I will post a pic of it. That extension made the tires fits nicely back to the same stock with with the stock tires, using the tamiya axles. The tire mates to the back of the plate of the axle and is then secures with a lock nut. This kinda take away from the appearacne of the drive hub, but was the only way i could come up with at the time.
