A wider rim would create a larger contact patch when upright, but at the expense of less contact patch when cornering, yes? The width of the tire can't increase without the height decreasing. The wider contact patch has to get that rubber from somewhere.
When I was investigating getting studs (ultimately got the Schwalbe Marathon Winter HS) I recall reading that the cornering and braking friction was significantly reduced (on dry pavement due to the studs, so I just made sure to go slower, and brake earlier.
