If there are holes in the wheels, opposite each other and close in near the hubs, I think we can make a very good guess at how people pull them off. I'd rather have four holes to reduce the risk of deforming the wheels, but obviously it is much easier to make a two bolt flat plate puller than a four bolt one. You just need a piece of 2.5"x0.5" steel long enough to span the two holes in the wheel, drill holes in it to match the ones in the wheel, grab a couple of bolts or pieces of threaded rod, and it's all over. However if the holes in the wheel are far, far apart (more than 6") you would need to reconsider the dimensions of the flat plate. Remember, thicker is far more effective than wider.
