Who produced the cup wheels?

[Ruivar]

Hi,
I know that the standard road wheels are Speedlines, but who produced the steel cup wheels? I just bought a set of cup wheels, and cannot seem to find any name on them. There are only some numbers...
I hope some of you clever guys know the answer

I believe Renault did for the cup series but only that series, i'm not 100% though

After a more thorough inspection yesterday, I found the word Michelin on the wheel. They are painted, so it was hard to spot at first.
I reckon the producer was Michelin then? Which is nice

Michelin, same as the original spare wheel off a gtt(the offset is different to the cup rim though)

Why is there such a big difference in the offset?

No idea why they done it for the cup cars, maybe done to help the car handle little better due to the slightly wider track.

Good point, mate! I guess that is the reason.
