Incorrect - contact patch area is based on car weight and tire pressure - a narrow tire has a different shape than a wide tire, but same area and same force per square inch = tire pressure.

It is the shape of the contact patch that makes the difference - think forcing a toy boat through water frontwards or sideways to see the difference.
