Man, you went from terrible to worse! Those GS-A will have about as much grip as snot on a hot skillet when the reach 5K. Please read the tire sticky in Infiniti General for some insight into what works and what doesn't. I know about the DZ101 and the GS-A are reviled among G35 owners who had them delivered on their car. Replacement was often accompanied by a bottle of Dom Perignon.
Good luck on the sunroof. Hopefully it is just a fuse, but even if so, you have to determine why it failed.
