I just noticed this today and was not sure if anybody else ever posted this info. I found out that they do have stock 16.5x6.75 rims that will hold the beads just like a 15 or 16" rim. They are M truck wheels. The centers are rivited in and they weigh a good bit more then a civi 16.5x6.75" wheel. The top 2 pics are M truck wheels and if you look close you can see the grooves on both sides for the beads and the bottom pic is a stock civi 16.5x6.75" rim. You can also see the rivits on the M truck wheels and the weld marks on the stocker.
