The present invention relates to a method for predicting the propensity
for a RMT steer tire to have irregular tire tread wear. The method
comprises the steps of: providing a RMT steer tire to be tested; placing
measurement points upon a ground engaging surface of selected
circumferential tread ribs of the tread of the RMT tire; progressively
rolling the RMT steer tire across a first planar side of a transparent
plate whereby the progressive movement of a footprint image of the RMT
steer tire is imposed upon the first planar side of the transparent
plate; recording the progressive movement of the marked measurement
points in the footprint image of the RMT steer tire imposed upon the
first planar side of the transparent plate; determining the amount of
lateral movement of each of the marked measurement points in the
footprint image; and if any measurement points exhibit lateral movement
beyond 0.060 inches, predicting that the RMT steer tire will have
irregular tire tread wear.
