You obviously have not ever examined the 1976 911 , Carrera , Turbo price list.

Nowhere on the page you posted , from a 76MY owners manual , does it state that the 6 & 7 in wheels referenced are forged. It is refering to the ATS cast wheels. Neither does it state anything about the specific options that get a car delivered with specific wheels or tires.

So , you think both the price list (with specific descriptions of the options) and the parts books are wrong.


Again , on the price list , BOTH the 7 & 8 in. forged wheel options specifically state 185/70VR15 & 215/60-15 tires. And the 50 series tires option does not mention wheels at all. And why do you think that a specific speedo , specially calibrated for 50 series tires on 15" rims , existed with a separate unique part number.


Why don't you try reading the material I referenced. You are making a determination without taking into account all the documentation.
