How would I do a tip test, or is it not possible?

Never used simulation before really, so I'm not even sure if this is possible.  We do consumer lighting and UL requires that the lamps pass an 8 degree tip test.  Generally we just make sure that the center of gravity is over the base and we're done.

 

Last Friday someone decided to try to put wheels on a floor lamp, so now we need to increase the base size since it tips easily with them.  What would be the easiest way to figure out the spacing needed on the wheels so the lamp does not tip?  Is this even possible?  We don't know what and don't care what kind of force is exurted on the top of the lamp, as long as if the base is at an angle of 8 degrees or less and it doesn't tip over. 

 

It seems this would be like the gravity example I've seen with the balls going down a funnel, but i'm not sure.
