Shaung, One way is to get the centroids of your irregular polygons (by exporting the centroids and then adding the new point layer). Then for each polygon find the tip farthest from the centroid and measure the distance (find the tip visually or by using shortest path measures to every node that seems far enough; activate the node layer for your polygons by converting the polygons to lines).
What you have are radius measures and centroids. Now, create a new field for the centroid layer and fill it with the max radius. You may now create bands with a radii measure using the 'build-to-value' function in bands toolbox. This may not be the best solution but may help solve your problem. good luck.
