Generally speaking, the XX.5 tubeless tires are the same height as a tube-type tire 1.5" smaller, or 2.5" in the bigger sizes. The 17.5's will be the same height as a corresponding 16" tube-type tire. 16.5's will height-match 15" tube types. They can be used interchangeably with tube-type tires without affecting speedometer calibration. On the bigger, dual-wheel setups, a tube-type and a tubeless tire can share the same hub, and share the load weight. For instance, a 20" tube-type and a 22.5" tubeless will be the same height, and can share a hub. Ditto for 22" tube tires and 24.5" tubeless. I did this regularly when I ran the maintenance shop for a concrete trucking business.
