Let's just consider that bit of information as good advice from a knowledgeable source. I don't know if anyone has had that happen to them with a car tire on a motorcycle or not, but I, for one, do not want to take that chance. Motorcycles are designed to be run with motorcycle-specific tires. But as it turns out, apparently car tires do work, and good for the guys that use and like them. It's just not for me. The way I look at it, the only motorcycle that should have a car tire on it is a trike, and they have two!
For those darksiders and possible future darksiders, just know that while the chance of a bead failure is probably slim, it could happen.
