They don't have the plain steelies. I sure as hell wish they did. I called and they said they don't know when they'll have them. The 15 x 7 plain steelies with the 4" backspacing are the wheels I want to run.
Summit has 7" on backorder.
The 6" and 8" in stock..
I bought the small bolt 8" with 4" BS but it really is 4.25 BS to the wheel lip (and 4" to the back side of the bead seat)
