Dimensioned drawing of a wheel inner ring detailing outer and inner diameters, width, hole size and bolt circle.
Part of 1992-1996 Ford Bronco Blueprints
This document is a hand-made blueprint/diagram (titled "Inner ring") showing dimensions for fabricating an inner beadlock-style ring for a wheel. It depicts two concentric circles representing the ring, with labeled measurements: an outside diameter (O.D.) of 16.3125 inches, an inside diameter (I.D.) of 11.9375 inches, and a ring width of 2.1875 inches. Bolt hole specifications are given: hole diameter of 9/16 inch, distance from the inner diameter to the center of the hole of 0.875 inch, and a bolt hole circle diameter of 13.6875 inches. A handwritten-style note clarifies that the O.D. dimension shown is for the author's rims: "My dimension here is for my 17" rims is 18 1/2"." The drawing was uploaded to a 1995 Ford Bronco gallery and appears to be one page of a two-part set (a companion "outer_ring.jpg" exists in the same album), suggesting a DIY beadlock or ring fabrication project. A reader can learn the exact machining/cutting dimensions needed to reproduce the inner ring, including hole placement geometry for the bolt pattern.

Frequently asked questions
- What is the outside diameter of the inner ring?
- The O.D. is listed as 16.3125 inches, though a note states that for the author's 17" rims the dimension is 18 1/2".
- What is the inside diameter and width of the inner ring?
- The I.D. is 11.9375 inches and the ring width is 2.1875 inches.
- What size are the bolt holes and where are they placed?
- The holes are 9/16" in diameter, located 0.875" from the inner diameter to the center of the hole, on a bolt hole circle with a diameter of 13.6875".
- Does this ring drawing apply to different rim sizes?
- The note indicates the dimensions are size-specific: for the author's 17" rims the relevant dimension is 18 1/2", so measurements would need adjusting for other rim sizes.
