Kumho should be quieter than Yoko 520s because of the directional arrow trends it have. I have Yoko 520s now on 215/40ZR17 but it pretty darn noisy... However the grip on the 520s are excellent in wet and dry... But it is wearing out fast at 5k miles with factory recommended inflation rate. I will try Kumho after this, which I assume should be cheap and good. Adam
