Yeah would be nice to get some a little bigger on them wouldn't it. Mine is the same with about 3" iron wheels and it is great on the concrete which is majority of the time but along the side of the garage on the packed gravel I have to lay plywood runners all along. Would be nice to get about a 6" solid rubber or something like that.

You could try Casterland.

 Bingo!

I've always though that bigger wheels on my picker would have be better. The tiny wheels get hung up on any grain of dirt. The thought occurs to me that it would be easy enough to move the wheel from under the arms to the ends, mounting them on fabbed and gusseted heavy plates coming off the tops of the arms. But would it be worth all the trouble?

That way you'd get a much taller steel wheel, and not raise the frame up to the point it wouldn't fit under a chassis. A 6" tall steel wheel would certainly roll better over anything rough.

But I still feel that cast steel wheels are probably best, they should slide and turn direction better than any urethane or pneumatic wheel could. Sometimes you have to give the hoist little kicks to get it in the right direction.

That said, to make it easy, I'd probably just replace your worn wheels with the same type and style.
