I e-mailed the seller. Tires are 335/35-17 which translates to 13.2" wide x 26.2" tall.
That is a very tall tire for a 911, 24.5"-25.5" is a good range for total hieght.

The seller could not or would not give me accurate dimensions on the wheels. I cannot tell by the tape measure what the true backspacing is or the actual section width of the wheel/tire combo.

The rim/tire setup I described above used 345/35-15 on 12x15 wheels.
The actual wheel width was 12.75" and the actual tire width was 13.5". The kicker is the hieght. The actual hieght of that tire was 24.5". What that does for you is allow extra space for the tire to arc up into the well as the suspension bottoms. A taller tire gives up that space and has a longer arc for the same movement.

With those figures you get an idea of just how huge the Gemballa setup is.
13.5x24.5 vs ~14x26.2
