Ditto on the cheap custom wheel from the seventies. That lug style was called a uni-lug, along with some other names. There's an oval hole for the stud, and it requires a short shank mag nut with an oval washer with either an offset hole or centered hole. They usually fit 5 on 4.5, 4.75, and 5" bolt patterns. The first and last bolt pattern used the offset hole washer, and the 4.75 used the center hole. It was a cheap way to make one wheel fit lots of vehicles, but, due to generally poor quality, fit was sloppy. Lots of radial runout if not installed carefully, and many instances of loosening lug nuts. Pretty much obsolete today, I'd go with a modern, tapered lug nut wheel instead of messing with uni-lugs.

 

I had a set of cheap sears wheels with a unilug set up. The holes were slotted digonally with a ridge machined all the way around. The lug nut had a corresponding ridge that sat against the wheel one. It was really a pin to get them centered when you put them on.

 

The center caps on my Aluminium ones have 'ET' on them.

 

They also look like a copy of some old Ansen uni-lug wheels.

The adapters also look like the old cast aluminum ones from Trans-Dapt.

 

If it wasn't for the sloted lug holes, I would say they were stock Dodge truck wheels. They match what was on my Dad's 78 Dodge stepside. They didn't have the slotted holes, however.

 

I know exactly what those wheels are. Redlightning is very close. They are made by Superior Industries in Van Nuys. Superior also use to make the custom steering wheels in the 60's throught about 90's. Because of the competition of American Wheels, Cragar, etc. Superior was close to going bankrupt. Superior Industries, no longer makes steering wheels or custom wheels, but now has contracts with the big car makers. They are the company that makes the wheels for GM, Ford, and some Dodge products. Those wheels you have were called Custom slotted steel wheels. They were actually pretty popular back in the day. Boy how we've changed.

 

Imlow and Hopper, you are both very correct. In addition, Superior was a stamping house that made "Private label" product for most other marketers of wheels even E.T. and Ansen ( Anderson/Senter Eng.), Appliance Wheel, Cal Custom,Sears,Keystone,Peerless,Wards,and a LOT of others. I sold tires/wheels for many years and this wheel was trash, but affordable and very available in any part of the country. I still have loads of washers for them to use in different application. Aluminum and CNC tooling has changed a lot since then. Cool post guys.

 

Thanks guys.
