There is no such thing.
measured up to a full inch difference in width between tires of the same size on the same wheel.

The 928 can tolerate a rolling radius of 26 inches on the rear
Huuh, should I be concerned? But it passed/wasn't noticed by the TÜV (German car inspection service)!

It can be very frustrating when trying to squeeze a tight setup onto a car.
What tire?
Doing a quick search, per the Tire Rack that size tire ranges from 25.9 - 27 depending on the brand & tire model.
The tires on the back of my S4 are 26.1 and my speedometer is off by about 4-5mph at 80mph.
285/35/19 = 26.854 (chart here: https://goo.gl/S8yLvg)

This is all going to depend on the tire manufacturer. I run a 18x12 with 295/30/18s on the rear of my S4 and if I have Pirellis on, there is a huge lip that helps protect the wheel, it also rubs the fender. If I use Kumho or Hankook, that extra lip is not there and no rubbing. The tires are actually an entire 1/2 of an inch narrower than the P's or Michelin.

When your speedo reads 80 mph you will actually be doing something in the region of 86 mph

If you went for TUV inspection with a GTS and anything but a GTS 17 inch factory rim set and correct spec tyres the car would fail
