4.5X15 steel wheels, what is your date and thickness?

[Harvey Weidman]

FYI I have 2 904 5x15 wheels dated 4/64 and 2 904 5.5x15 dated 8/64 all KPZ all 3.7

Are they bimetal? If so they are in a different category. Interesting anyway though...
Do they have the hubcap dents? If so they may be the same die as the street wheels.....

They are bimetal. They do have hubcap dents.

They are bimetal. They do have hubcap dents.

They (I have some bimetal 3.7s here to look at) look like the same stamping to me as the production wheels.
That begs the question if all centers changed at the same time?

Except for the C2 of course.....
Wonder why they didn't continue in production the 3.9 when the decision was made to make the C2 wheels thicker than the rest of the wheels?

I have original Lemmerz 3/65 and they are 3.9 on 911

[Rich Lambert]

Four 5/65's that are 3.9 and one 12/65 that's also a 3.9.

What about the 906 wheels? I think they lack the 3 dents on the center, but I may be wrong, and they are supposed to have been made early in 65. Correct?

Following the evolution of the 906 wheels would be another thread. Maybe starting one in the "other Porsches" area.

I just saw another 1/65 3.7 in the for sale forum.
1/65 is still the latest 3.7 posted....and 3/65 the earliest 3.9.

Both Lemmerz or KPZ?
Are there 2/65 wheels? (I have never seen one).

Here is the Factory Service Bulletin talking about the 3.7 vs 3.9.
