New tires making odd humming noise

[Chr0meSplAt]

First a little run down -> 2019 Type R, 18k miles, stock suspension, Koenig Ampliforms 18x9.5 +35

So just a few days ago, I replaced my Michelin PS4S 255/40, with a new set of Falken r615k+ 265/35. I had them mounted and balanced, with no issues on fender clearance. On my first drive around town, I experienced this humming/whirling noise at 45mph, continuing through 60mph. The noise does not occur at any other speeds, and seems to only happen on certain types of pavement.

I went back to my tire shop today and had them remount/balance again, but the noise is still persisting. Im fairly positive that it’s not a wheel bearing (no noise from my previous tires+ the noise only occurs when driving straight+ wheel bearing shouldn’t go bad at 18k.)

I know this may be a simple fix, and I’m probably missing something, but has anyone experienced this before? Do the tires have to broken in? Any insight would be appreciated!

I suspect that is just a characteristic of that tire - a lot of super sticky, track-type tires have some resonances that sound pretty strange if you aren't used to it. Tire Rack even noted the 615K+ had "tread growl" - read under "What We Learned on the Road":

More than likely a tread characteristic.

If the balance was good you could also check the alignment and see if that helps.

It’s normal. I have the same tires. Seems to have gotten quieter with miles on them though.

Having the same issue with my RT615K+. 265/35 on 18x9.5 +38. Loudest from 40-50mph. I can hear the noise while turning. A lot quieter at 70+ but maybe the general drive noise is covering it up. Feel little to no vibration.

Gets better when they wear a bit

Happy to report that @BoostedDreams was right, the noise has subsided. Guess the tread had to break-in or like mold release agents needed to shed. Was regretting purchasing these tires for a bit but am pretty happy now, especially with how affordable these tires are and how they can take track abuse. Will see how they handle a GA winter. Hoping they don't flat spot or at least if they do, will go back to round after a few miles. Car is parked in my garage.

Only down side I’m having now is they are a magnet for picking up screws and nails! I had 3 holes in 6 months!

Wow that's wild. Haven't had that issue so far but now I'm extra glad I got the insurance through Discount Tire. Guess that's the price for sticky tires.

Perhaps its better to have a dd set of wheels with a/s tires and a set of summer/track wheels with sticky rubber not driven daily. Next spring im getting some fancy summer only wheels with sticky rubber.
my 2 pennies.

Summer wheels. Make it seasonal. Used to live in winter park.

I thought about doing that before I sold my 2nd set of 18s but I just don't go to the track often enough to make it worth it. Definitely the way to go though if you can and will make use of them.
