What you are describing is the same effect as using a lower pressure in the same tire (that is, reducing pressure reduces "vibration"). The problem with running a lower pressure in narrower tires is that it reduces the load that can be accommodated (eg, for a given tire, heavy people use higher pressure and lighter people can use less).


That is, you are saying using a higher pressure in narrow tires reduces "bouncing/shaking". But narrower tires run at higher pressures are less comfortable.
