Might I suggest metal wheels.

In my experience anything else will develop flat spots over time.

And over buy in terms of capacity...some toolboxes hold well over a
thousand pounds since metal items add up fast.

I'd go with polyurethane over steel. *Like thesehttp://www.sunray-

IMHO polyurethane over steel is the best of both worlds. *You get the
weight capacity and flat spot resistance of metal wheels. *Ability to roll
over pebbles and other small trash that would make the metal only ones come
to a stop. *And a heck of a lot less noisy to drive around.
700LB capacity on this 4x2 swivel is about the same capacity you'd find on
an all steel wheel of similar size.

That is a good alternative....BUT....any heavy load will set flat
spots on the casters.

I am in the process of changing out dozens of casters that I used
under machines that have developed a set.
