Interesting article, from it:

Surprisingly, low profile and wider tyres are not as safe as tyres with a smaller contact area in the wet. As the weight of the wheel is spread over a greater area, the ground contact pressure is lower and therefore is less able to cut through the water. Think of it as trying to cut through butter with the flat of a knife rather than its cutting edge.

Regarding the thinking that 3mm min would be better than 1.6mm min, it would of course be, but then 5mm probably beats 3mm so where do you stop? Especially as tyre manufacturers are supporting this

Correct. Most motoring organisations strongly advise to change your tyres by the time the thread is down to 2.0mm though
