DESIGN PATTERNS FOR A TIRE SIDEWALL

摘要

A tire sidewall having a surface with a distinctive design pattern is described. The pattern has a plurality of ridges 20 of similar crosssectional shapes of varying sizes, each ridge 20 being substantially parallel to an adjacent ridge 20. The pattern has a plurality of parallel ridges 20 extending in a direction between 45.degree. and 0.degree. relative to the radial direction. The ridges 20 of the pattern vary in size or depth and are preferably arranged in a repeating pattern varying from small to large to small sizes or depths. The preferred patterns have at least three distinct sizes or depths of ridges arranged in a sinusoidal or a sawtooth configuration and have a variation in cross sectional height of at least .010 in preferably .015 of an inch between consecutive sizes. The design patterns when incorporated into the sidewall 12 of a tire 10 may form a circumferentially continuous wide decorative band with striped or solid alpha-numeric markings superimposed over a portion of the wide decorative band.
