When you change the dimensions of the tire, it changes the *shape* of the contact patch, but the magnitude of the contact patch (square inches of area) remains the same. A wider tire has a wider contact patch, but also a shorter one.

So a 155 tire and a 320 tire both 26" in diameter have the same contact patch in square inches? I don't think so.
