Answer:

Don't do it. WD-40 will make the tires slippery. Kind of like driving on ice. You could very easily lay the bike down in the first corner you take. Never ever put anything on a motorcycle tire. If the tires are in questionable shape, replace them.
I am really interested in knowing what these 30 year old motorcycle tires are that you somuch want not to discard, I know there are some brands that are hard to come by. I my self is currently in a show piece restoration project and wouldnt mind a set of original donlops for my 1964 triumph good luck
we used to run car tires on the back of Harleys all the time WITH NO PROBLEMS to all the idiots who dont think so! However in this day and age you can find motorcycle tires all the way up to a 350 so car tires are not needed. I dont know your rim size or standard tire size would need to know that to figure the largest tire your rim will accept.
I read a question, in Cycle World, about someone doing exactly this on his Gold Wing. He had put already 30,000 miles on a rear car tire with no problems. However, Gold Wings are leaned over gently compared to sport bikes. Rider magazine did an article on this last fall. One of the problems is that, if necessary, the motorcycle tires could maintain stability as low as 12 psi. The car tires got real jittery if only a few psi were removed. Having ridden for a long time, I admit that I have neglected looking at my tires occasionally. only to be surprised that I'm already running pretty darn low. Glad I didn't have a car tire under me those times. Rider Editors called this going over to the Dark Side. Go for it if you want to. Honda makes a LOT of 1100's. Which one do you have? The Shadow uses a 15 inch rim. The V65 used a 16 incher. The new CB1100 uses an 18 inch.
Assuming you have a 170/80-15 motorcycle rear tire, a 165/80-15 car tire will fit. You will lose turning traction -- anything that reduces traction, such as water, could give you a low-side crash.
