I have Toyo Proxie 245/40R18s on my car right now. I rotated the tires front to back (directional tires) and immediatley noticed a few things:
1. At speeds
2. There's another, higher pitched resonance at around 30 MPH, which will go away as I speed up. The noise goes away above 30 MPH, but comes back again at around 60 MPH. From 60 MPH on up, I hear the same higher-frequency tire noise.
I swapped the left-side tires back and the low-speed, vibrating hum has gone away completely. I haven't been on the highway yet, but the resonant, higher-pitched tire noise at 30 MPH is there, but quieter and now sounds like it's coming from the back.
The tires were last rotated ~5kmi ago.
I inspected both the front and rear left-side tires and nothing jumped out at me. The sidewalls looked perfect, no feathering of the tread and no dents, bubbles or anything other obvious signs of a damaged tire. The tires all have ~ 7/32 tread left, FWIW.
My question is, what is this noise and might it require replacing that tire? I have a Subie, so that would mean buying a new tire AND having it shaved down to 7/32 to match the other tires.
Thanks for your input, guys. Wasn't sure if this should be in the Tires section or maintenance section. I apologize ahead of time if it's in the wrong section.
