Someone should write a book on "Rally/Ralleye/Ralley" wheels. Chevy spelled it Rally. There are so many aftermarket Rally's. But here is what I believe is true. There is so much bad information about these wheels, I hope I don't add to it.
1. Camaro came out in 67/68 with Rally wheels. Car Rally's. Can't use them, they are 15" x 7", lug pattern 5 on 4.75. They are 5 slot like yours and the style cap as yours. (pop on Police Cap/Disc Brake Cap). Vettes, Monte Carlo and others had Rally Wheels also.
2. Chevy 2WD truck went to 5 on 5 in 1971.
3. The 71 and up 4x4 stayed with 6 on 5.5. The early AD/TF truck are 6 on 5.5. You are correct that yours is that pattern.
4. Chevy Truck came out with Rally Wheels in 1975. 15 X 7, 5 LUG, 16 Slot for 2WD and 15 X 7 or 15 X 8, 6 lug, 10 slot for 4WD. Screw on cap.
5. I consider anything else as aftermarket. I saw your 5 slot, thought they were Chevy from what you said and figured they had to be 5 lug.
6. The first generation Blazer did NOT come with those wheels. The 2X4 and 4X4 Genuine GM Rally is not a "Blazer Rally". The 1975 is the first year.
It was available on C10, K10, K5 and some vans. RPO N67 Wheel and RPO P06 Trim Ring.
I have seen aftermarket 5 Slot 15" Rally Wheels for 5 X 5 pattern and 6 X 5.5 Pattern (yours). Have not seen any 10 slot or 16 slot. Either I missed them or there is a GM patent.
Lots of car Rally's. Lot's of Rally's of all kinds for all kind of vehicles. Some of which don't look like rally wheels to me. Just a cool name for sales.
No need to take off your cap. I was just trying to identify the maker.
The word slots, when used with Rally Wheels, is the decorative design slot/opening not the thin slots between the flanges where standard wheels are riveted or welded.
I guess I did write a book. Dang it!
Gentlemen, please limit your wheels discussion to “Truck” wheels. Thank you
