Will 16 inch Fuchs, with low profile tires, fit on a 73 911?

I want to put 205 16 45's on my 911 and was wondering if this is possible or
un-advisable.

High performance tire selection is limited on the stock 15 inch rims and the
lower profile tires on the 15 inch rims really changes the gearing of the car.
Without doing anything more then rolling the fenders is there a 16 inch Fuch
that will fit?

Many thanks,

Chris
