Hi guys,

Since I switched to my winters I have got rid of the low pitch howl that occured at 130-140km/h. Its like a resonance of some sort that only comes on at those speeds regardless of what gear, throttle position, or even neutral. It is very annoying and I was wondering if anyone else is getting the same with the 135s? I have stock tires (goodyear). Keep in mind, my car is a station wagon.

Does anyone know what I'm talking about?

 

My car has 135s and Goodyear Runflat NCT5s. I get no noise like your describing. I do get tyre noise depending on what surface the car is running on though. Maybe the noise is from your winter tyres.

 

Had 135's on my old 545 with PS2's, no such noise on my car. What tires do you have on the 135's? Don't think it is rim related, most likely a tire issue...

 

My tires are the stock "goodyears", 245/40/18, can't recall the model number. The noise is not dependant on the surface that I am driving on. Its more of a resonance than anything.
