That isn't always the case. Generally speaking, higher air pressure will increase the contact patch, as the tire doesn't roll over as much on the rim with more psi. But you will reach a point of diminishing returns.
Of course, it all depends on the tire, the car, the alignment, and so on. But for most cars, higher tire pressures = more grip.
