@mpgxsvcd What's the crossover point on your car for when wind noise becomes (subjectively) louder than road/tire noise?
I tried paying extra attention to comparing specific noise sources in recent highway driving in my 2021 M3P (with double-paned front windows). Everything below assumes a
decently smooth, quiet road surface (not necessarily fresh pavement, just average-ish). If it's really loud old asphalt or concrete or such, then of course road/tire noise will dominate at even higher speeds.
There is definitely a crossover point where wind noise becomes louder than road noise in my car, but it is somewhere north of 80mph, and I don't usually drive faster than that, at least not for long / only to pass quickly, due to traffic and/or ticket risk.
At 75mph, which is a typical highway cruising speed for me when traffic allows, wind noise is still quieter than road noise.
Now my current tires are a bit louder on the highway than the stock foam-lined Pirellis! And later (well after wheel+tire change) I replaced a few rubber bushings with solid metal bearings (top hats and FLCA), which in theory should transmit road noise a bit more clearly into the cabin. I didn't notice any drastic noise level difference after installing the suspension parts, but I would guess a controlled test with a microphone would pick up an increase.
However even when 100% stock down to the tires, road noise was still louder than wind noise up to
at least 75mph, as best I recall, and I think up to 80+ mph as well. I'm sure my slightly louder tires have raised that crossover point where wind noise begins to dominate, but not drastically, I think.
Having a loud diesel truck or a gas car with an obnoxiously loud exhaust next to me will certainly dominate over my own car's noises, but I try not to cruise right next to such vehicles for long.
"How many people drive at 60mph?" Answer: Many when that's the pace of traffic!
