The importance of the ability to predict Tire noise at design stage can be assessed from the fact that the Tire noise remains the second largest noise component in an automotive vehicle external noise.

SilentRoll allows tire engineers to consider the effect of various tire components and the tread pitch designs. Using SilentRoll the tire designers can optimize a given tread pitch combination for most desirable sound signature. The tire could be divided into multiple tracks for track offset effect simulation on tire noise. SilentRoll gives as an output the optimized tread pitch sequence and also the dB and dBA levels of tire noise.
