When selecting a wheel, make sure to get the weight capacity needed along with the diameter, width, and axle bore. In some cases, the hub length is critical to a good fit. As with casters, the larger the wheel, the easier the push will be. Pay attention to hard vs soft wheels, propensity to flatten and marking vs non-marking.
Remember that larger diameter equates to ease-of-roll while wider width equates to higher weigth capacity.
