NOISE GENERATION MECHANISM OF CROSS-BAR TIRES AND ITS COUNTERMEASURES

The dominant noise generation mechanism of cross-bar tires is the sidewall resonance with the tread vibration caused by the collision between the lug blocks and the road. There exist some natural vibration modes at 450 Hz and within the vicinity, which has vibration patterns distributed along the sidewalls. For noise reduction the following three methods are proposed: (1) Spacing the cross grooves perpendicular to the tire sidewalls; (2) Reducing the hardness of tread rubber; and (3) Increasing the stiffness of the tire carcass.
