    Wondered what you have been up to. Good video. Lots of good information. Had no idea that people used car tires on a bike. Seems like a no brainer to me. Got a pristine ’99 BMW R1100RT last summer but blew out my knee and have not been able to ride it. Hope all is well with you.

    I’m researching going to the darkside. My question would be about the diference in weight of a motorcycle vs the car,
    would this not affect the flex of the tire. So what I’m inferring is, the bike and lack of weight compared to a car would not cause the tire to flex so much?

    • You are correct, a lighter motorcycle load would cause a car tire to flex less under STATIC conditions.

      The problem is the car tire sidewall flexes more when turning, while a motorcycle tire is constructed so that instead of flexing to turn, it remains stiff generating camber thrust. This is what you need to turn at camber angles.

      I hope your research leads you to conclude motorcycle tires are safer.

    Thanks for the info Tony. Useful stuff. Just so you know, the intro, and outro music is very much louder than your voice. Maybe your audio guy (or girl) can match em better so us old guys don’t have a coronary when the end music comes on. Not really a big deal, I just thought you might want to know.
