Rear tyre size - ZR-1 Net Registry Forums

Hi guys,
Here in Italy we (zr1 owners) have a problem with the rear size tyre.
We have an only brand who produce the 315/35/17 tyre.
Me and some other guys, zr1owners, want put on the rear the 335/35/17, it's a less rare tyre and wr can choose Michelin or Pirelli.
But we have an other problem, we need a "paper" where GM tell us that there are not technical problem using the bigger tyre (always on the original rim).
Someone of you know how I can contact GM for have this documents?
Thanks to everyone
Max
