Tyre OR Bearing Noise
The noise is really driving me nuts. Changed to a set of 17" rims with 215/45/17 Dunlop LM701s couple of weeks back. The tyres were pretty quiet initially but a few days back, i'm getting what seems like very bad tyre noise, which is apparent past 40 km/h and gets louder as the speed increases. The shop where I purchased my tyres from insisted that such low profile tyres will generate noise. I'm not convinced that all low profile tyres of this size will generate this amount of noise. Cruising at 100km/h, the noise drowns out everything including the engine noise. Someone suggested that what i'm experiencing is bearing noise. BTW, I'm driving a W124 230E. Qs is, how do I differentiate between bearing noise and tyre noise?
