Well, actually, I did.
But what I meant was the tyres influence compared to frame & fork influence. But I did experiment with all sorts of frames (steel, alu-carbon, road, MTB, touring geometries...).
Important factor is also tyre quality. Good 28 mm tyre was softer than a heavier, lower quality 37mm one. But with same tyre quality, jumping from 23 to 28mm for example adds a lot more cushioning, than swapping alu with a carbon fork - in my experience.
