Nope, that's not correct, except that two cars would be spread across two lanes. PSI is not the only factor. Take, for example, our concrete road panels here in Seattle. The weight on one end forces that side of the panel down, stressing the connection to the previous panel, and also lifting the panel from the front. That force is not significantly changed by tire width.

I wish you did a little more studying before talking so authoritatively.
