Perhaps I can clear this one up with the following spec I obtained from the factory for the owner of a 1976 Carrera 3:

engine 666XXXX
gearbox 165XXX
color B2=continental orange
interior 36=leatherette brownbeige,seats leather,seatinlays Tweed
delivered to HG=HongKong
options U56 (groupnumber contains 058=shock absorbing bumbers, 197=stronger battery, 474=Bilstein-dampers,
568=colored windows, 650=sliding roof) and 395=tires front 205/50 15,rear 225/50 15, 399=colling system,
401=forged alloy wheels front 7x15,rear 8x15, 441=electric antenna, 462="Carrera"-script black, 481=5-speed gearbox

As can be seen there are the two options of 7&8x15 Fuchs M401 and the low profile tyres M395.

However just to confuse matters for the 1977 model year M395 became 6&7x16 Fuchs with low profile tyres as fitted to the UK 'sport' model.
