Tried it. At most it's 15%-20% more quiet than the noisiest Korean tyres I had.

My size is 225/45/R18, bought it for RM430 a piece, found out Kedai Papan Klang was selling 365 a piece.

Nothing special, except for its amazing price. I should have gone for Michelin PS3 for better grip instead.

No comments on grip. I don't rempit with my car.

I suppose it's alright for its price, you will get better result by using that savings on interior sound deadening. I think that will cut down noise level more effectively.
