What you say would be true if the tire was perfectly circular since a circle will only intersect with a line at one point regardless of diameter as you said. But the tire deforms where it meets the pavement so it is not a perfect circle. The amount of deformation is affected by a number of things such as vehicle weight, tire pressure, and sidewall stiffness. Given that all these things are equal, and only the tire radius is allowed to change, the same amount of deformation in a tire of a larger radius would result in a larger area in contact with the road.

Picture this shape : (_)

As you increase the size of the round part of that shape the flat part at the bottom would increase in length.

Do you really buy cars based on the people other people associate with it? Who cares?
