I wonder...are the reasons for darksiding the Xciting because you find that type of tire more comfortable or is it economics?
I believe a motorcycle tire is inherently softer than a car tire and is so for a reason. Having a flat on a car tire then seems less likely. With that said, I know a person who had a burgman 400 who suffered a very serious accident shortly after darksiding. He was entering a curve on what was a dry, debri-free road. That's how he remembered it when he woke up in the hospital.
I look forward to your review of how the car tire worked. I might just do this myself.
