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.
Flat Free (also known as semi-pneumatic) are extremely popular wheels. Made to perform like a pneumatic tire, they are filled with a lightweight, microcellular polyurethane foam. They retain the lightweight, bounce and cushion like a pneumatic tire, without the nuisance of air leaks.
Flat free wheels will typically experience temporary flat-spotting even when loaded within the acceptable weight limits. They tend to flat spot immediately, a little more after a few hours, a little more at 24 hours, and not much more after that regardless of time. Flat-spotting is more noticeable in warmer weather. The flat-spotting will roll-out and dissipate after a few minutes of rolling, depending on the size of the standing load and extent of the flat-spotting. This is a normal occurrence of these wheels and is not a product failure. If your application cannot tolerate this temporary condition, another material type may be preferable.
