Your not getting it , all i'm saying is that in all the literature that I can find (both factory and outside review).

For 1976 , it shows the 50 series 15 inch tire option (m395) is for the tires only , at a cost of DM800. Maybe they left off the text concerning the wheels. This price seems pretty expensive for just tires . But at that time these tires were almost a brand new design. , so it's very possible they were that cost alone.

Here's an excerpt from a write-up by Michael Cotton concerning the 1976MY 930 :

"For the 1976 model year (commencing August 1975) Pirelli P7 tyre equipment became available at a quoted extra price of DM 800 , though a standard fitting for the British market. These radial-bly tyres , hand-finished and considerably more expensive than mass production tyres, had been developed by Pirelli and Porsche engineers at Weissach on Porsches unique 4.5-metre drum, on which the tyres can be run inside the perimeter rather than on top of a rolling road surface. Its construction resembling that of a racing tyre, the P7 was the last word in road tyre equipment and truly matched the capabilities of the Porsche Turbo. The wheel diameter remained at 15 in and a new speedometer had to be fitted to compensate for the 50 percent tyre profile."

So , since 7 & 8 inch wheels were standard on a 1976 930 , the 50 series option (at DM 800) obviously could not include the wheels. That is the basically what the reference above says - this option did not include wheels. At least in 1976MY for a 930....and in 1977MY ...I do not think there was a 15 inch 50 series tire option , I do not have a 1977 MY option list or price guide listing options.

Echoing the Cotton reference , again is the price list . It clearly shows this is applicable to that year C3 also . And as stated prior : m493 & m401 , the two 7 & 8 in. wheel options (black center & anodised center) , both are specifically notated as coming with 60 & 70 series tires. The m395 text description states only : "Reifen".

Also echoing the M. Cotton reference is the 1976 US sales brochure which lists the 1976MY 930 with 70 series front & 60 series rear tires as standard fitment.....with any option concerning P7's (m395) on a 930 , wheels are redundant. There is no P7 series tire option specifically for a C3 vs. a 930 - only one.


I'm only going off multiple sources of evidence / documentation , that I have access to. I do not believe it is all incorrect , just too many references. I researched the 1976 m395 option some years ago , that is why I am farmiliar with it. It was also available to be fitted on a 1976 2.7 Carrera with yet another distiinct speedo calibrated for 50 series tires .....a mechanical unit.


If you want to call trying to be accurate nitpicking , then fine by me .
