Motorcycle Tire on Car Wheel

Question for those in the know. Will a motorcyle tire fit on a car tire wheel. I may have heard sometime in the past that a 15" car wheel is a different 15" size than a motorcycle wheel. How about a 16" wheel? Reason I'm curious is that I bought a dragbike wheel and swingarm and am thinking about adapting to my older KZ which is going through some frame mods this winter.

Thanks for the help.

That would be 'Flirtin' with Disaster'.

18" is always 18". I would think that the sealing bead would be different.

One think to keep in mind is your only on 2 wheels if one goes you goes.
