Yeah inertia and weight VS actual traction are all factors, a good set of A/T's will do great on most Dyno's ..
I have always been told that slicks do calculate to lost hp on the dyno vs a street tire but I have never tested it back to verify. As for your scenario I would assume lighter and shorter tire would free up hp as well.
Maybe if you didn't air them up and they wrapped/dragged around the roller?
I think smaller tire would do about the same. Only benefit would be the rotating mass reduction. I think it would even out on the roller because it takes a bit longer to spin up due to more tire rotation/distance to spin the roller the same amount.
I've never done it of course so my idea could be completely wrong, but I'm sure others have and I'd also like to know the results.
