I had not thought of the issue of noise. Assuming you have similar tread, and a similar contact patch to existing tires, wouldn't noise remain similar?
If I recall the assumed cause was wind and the open structure of the tire. I don't know how much contact area and material was impacted the sound. Noise seems to come up anytime these tires are mentioned. The article posted doesn't delve into it. Just a light mention of noise being a factor discussed before.
Oh, that makes sense. Like blowing across the top of a bottle. Those spokes may end up acting like reds as they spin at high speed. Interesting!
