Well here was my birthday wish come true, the shop was able to get the 355/25/19 mounted on the rear rim!!!
It has a small gap between the tire and the rim on the inside and outside, but with the wheels powdercoated black it should look just fine. I didn't want to destroy or modify the original 935 wheels, so this is a dream come true!
BTW this is one wide mother ufcker
Enjoy:
Notice the width of the dually tires behind it...very similar in size...
