air-plane propeller like sound when driving

[Spuit]

Hi Fanatics,

I have standard e90 model, I recently changed my 16inch wheels for the ellipsoid 18inch wheels. the car now makes some propeller like sound when driving, when driving slow the sound is audible, but when I start going fast maybe like 120km, the air-plane propeller like sound stops, until i slow down then its loud again, i have eliminated the bearings as this sound only came up after i changed the wheels.

any idea whats causing this sound? you help is much appreciated

Regards
Thabo

Are the wheels new?

Yep, I would suspect tyre noise - what brand and tyre of tyres are fitted? Were they new or used?

When I had my vtec I had k@k dunlops on and had the same noise, as soon as I changed to pirellis the noise was gone.

Try and get a better set of tyres - Hankooks offer great value, just the rear tyres that are always going to be more pricey regardless of what you get...

Yup me too, had cheap ass dunlops on my e46 and had the same noise, back to Bridgestone and the noise was gone.
