I'm going to say yes and no, not necessarily!- the 16x7" fuchs rubbed on mine and caused blistering of the paint on the fender!! - depends on the car-
I have 205/55-16 on front and rear- now, the fronts are 6^ and rears are 7" - but for our cars the proper diameter for the speedo is 205/50-16
since you already have 7" on rear of car with your 15" rims your 16" may fit , even after having fenders massaged to get the 7" to fit, its so tight, before I fix and repaint I will be going back to 6" rims, with spacer, - you see the 7" rims come out a whole inch further, the back space is same as the 6's, - if they were lets say a half inch less on outside and half more in, they would be perfect. but that is not the backset for the early staggerd 911 fuchs wheels. - but like I said, it varies from car to car, so good luck!!!
I'm curious if you tried fitment of your front 6" wheels with those tires in the back of your car? If so, did that fit in the back without rubbing?
