Don!
Thank you for the information. It's just what I needed.

You have to have them balanced with a lug type balancer.  Most shops are just too lazy, don't know, or don't think YOU know.

That is why the center hole diameter of the wheel is of crucial importance because it has to match the diameter of the boss on which it will rest. If indeed there are two (2) ways to mount bolted wheels, what is the governing criteria in selecting the proper method? Thanks,
