The issue with rims is the weight/mass of the rim away from the hub. The more mass further away the harder to get into motion. You can have 2 rims that are both the same diameter and weight but can have different performance based on how much weight is centered and how much is pushed outward to the lip of the rim.
Each tire weigh differently as well.

A Dynojet measures how quickly the engine can accelerate the drum over a timed period and rpm. The quicker and faster the drum gets the spun, the more power to the ground. Since the engine has to work harder to accelerate the heavier wheels, it will certainly show up in the numbers. Simple physics.
