The wheels you see in the first pic are what the dealer orders as "slave" wheels from the factory. The slave wheel used to be a solid rim with about 2" of solid rubber all round it. These were rather expensive to ship round the world and over the last few years with the increase in scrap metal CNH lost rather more than they ever got back.
So now if you order on slave wheels you get the rims for the tyre size you want with a wooden/steel band wrapped round them. Once in your yard, fit the tyres the customer requires.
