That is a flat center wheel as used on Rockwells, Unimogs, Militaries, etc.... Read what Stockton wheels says about them.
Available in bolt circles of 6x7.25", 5x6-7/8", 5x8", 6x8.75" .
Aside from the fact that they don't offer that wheel in the Toyota bolt pattern a flat center wheel will not bolt to a Toyota hub because of the caliper.
