This is the Firestone RH type disc wheel having the solid/unbroken side ring on the face side of the rim. The RH disc wheel shared its side ring with the RI type demountable rim. Thus all the rings have RI coding. The key identifying feature of the 6(4.33) ring is its 1.125 height measurement as shown in the second diagram. The narrower 5(3.75) rims ring measures 1.00 while the wider 7(5.00) rims ring measures 1.312. Also pictured below is a NOS 20 x 7(5.00) ring showing Firestones stamped identification on the inside of the ring. Commonly this stamping is long gone after 80 years, so the measurements given above are the surest way to identify the 6(4.33). Thanks. Stu
