5 lug Ford 15" x 5.5'' steel wheel aplication

[Sportyworty]

The regular 15 inch wheel was a 15 X 5 and the heavy duty/HiPo wheel was a 15 X 5.5. The 15 X 6 was new for 1965.
Now the T Bird also used a 15x5.5 with the large vent holes however they were rivited flame cut as opposed to the welded HiPo center with small vent holes. Look on the inside between beads for some more stampings. Kelsey will have KH or K2 etc. Some will be dated there also. They appear to be T Bird which many use as the HiPo 406/427 based on the large vent openings but hard to tell with out a side by side. Just look for the K stampings and see if they are welded centers. Hope that helps
