Dark Side?

I heard about this, and I thought that was interesting.

Car tires are not designed for the dynamics of a motorcycle and can affect the handling, stability, and braking of the bike. They have different profiles, construction, and rubber compounds than motorcycle tires, which are engineered specifically for the unique demands of a bike.

Is stability and braking a problem?  I've seen YouTube videos where someone has put in 15,000 miles on the car tires on a Goldwing.  He had no problems with braking.  If fast, it seemed that he got better braking in wet conditions with a car tire.  In another video I watched, the car tire gives you more stability if you're pulling a trailer behind.

One thing I think though, is it's not meant for new riders.  A car tire can lead to reduced maneuverability and a less responsive ride.  You'd have to put in more effort when counter-steering.  This can be particularly dangerous in emergency situations.  I'd say, if you're a season rider of a large cruiser bike and are familiar with the controls of the bike and know how to deal with emergencies, it's probably safe to go to the dark side.  Half the price of a motorcycle tire and five times the life of the tire?

Dark side on a sports bike?  Nah.  It wouldn't look cool!
