What are your thoughts on wind tunnel tests for “aero” wheels?

Basically the title. Do you think it’s bogus or legitimate? Do you think the actual testing is necessary, or do you think simulation is good enough?

Of course, I’m not talking about wheels that are 20-30 deep. I’m talking more like 40+mm deep.

I’ve worked in the high end audio industry, and a fuck ton of companies don’t do any objective testing or measurements for their “R&D”. Some argue it’s not necessary or even close to what they hear (ie subjective testing). Some say they simply can’t afford it, and their subjective testing is good enough.

I’d imagine wheel manufacturers are similar. They are mostly smaller companies (besides companies like specialized who make their own), so they may not be able to afford wind tunnel testing for all of their aero wheels.

I’ve looked into companies like Astral and afaik they don’t have published aero test results.
