I don't think so , Mike.  Short answer, good enough for the girls we go out with, is that if you increase the weight on any tire by 50% or more, there will a slight rise in air pressure, since the contact area will increase, which increases friction, which increases heat, which increases pressure.

I don't know your weight, but it's unlikely your weight will increase the weight on the tire by more than 10%, which is negligible in terms of increased pressure.

I suspect Mike's tongue was firmly planted in his cheek, but it does betray the fact that not everything that seems like it would be so is in fact so.

It's like the contact patch of wide tires. Everybody knows that wider tires equal a bigger contact patch. Except that all else being equal on the vehicle, this is not so. Wider tires change the shape of the contact patch, and therefore the rolling resistance and cornering characteristics, but not the size of the contact patch (which is shorter front to back and wider perpendicular to the front/back of the vehicle).

Intuition is not a very good guide.
