This is how a car tire works on a bike
 

Scary shit, car tire on a goldwing.

So, he just did it for the video, or is this his permanent tire because he was too cheap to buy a real one?

I dont know, I have seen some bikes with car tires on the back, but they are usually folks who do major miles and really need the life of their tire to last.

Here is another one

I can see how it would last a long time, but it will probably hydroplane more often, as any small car driver with wider than stock tires can attest.

thats gotta make for an evil handling pig. no thank you

Must of them will tell you there's no discernible difference in handling.
Of course, most of the "car tire is good" guys couldn't tell the difference between a super sport and an overweight ill handling pig to begin with... other than "the seat hurts, and the bars are too low." :td:

that wold HAVE to handle badly. considering what we're used to riding, that certainly wont corner like any R6.

People were using them on choppers when the wide rear tire thing started, but I think that was because tire manufacturers didn't make motorcycle tires wider than a 230 or 250.
