What happens if I fill up normal car tires entirely with foam, as opposed to air?

Question

I'm asking because foam-filled tires do not become flat, and air pressure is never an issue.  I want to take normal car tires and replace the air inside with foam.  Is this a good idea?  Thanks for reading.

It's been done. The foam will heat up at high speeds and melt, causing tire balance issues and eventual failure of the tire.

If this was a viable solution, they would already be doing it. What will happen is that the foam will crush and break up in pieces, and soon you will be back to having a flat tire.

this is an interesting concept, but a horrible idea, if the foam is too stiff it will destroy your cars suspension and have a horrible ride, if it is too soft you will be all over the road, 

they make an aresol for that you know..

I've done it to a wheelbarrow and the nails and other things didnt do anything to it, but I dont know about about a car, unless you fill it more than you're suppost to. Good Luck
