Wear-indicating tire

Abstract

A wear-indicating tire includes a tread section that is formed of a plurality of visually different plys that present a visually different effect as the tire tread wears down. The sidewall section of the tire also includes a pattern or that cooperates with the visual signal from the tire tread section to provide an overall aesthetic appearance that is pleasing.

We claim: 
     
       1. A tire for use on a land vehicle wheel comprising: A) a sidewall section; and   B) a tread section connected to said sidewall section and which includes indicating means for indicating the state of tire tread wear, said indicating means including a plurality of different plys connected together in layers and each covering essentially the entire surface area of said tread section and each having a treat pattern which extends over the entire surface area of the tread section with an innermost layer having a pattern shape which is different visually from the pattern shapes of all other plys, each ply further including a color which is different from the color of all plys so that as said tread section wears down during use of the tire, visually different plys will be exposed to indicate the state of the tread wear, a double warning being formed by the different color and different tread pattern of the innermost layer.   
     
     
       2. The tire defined in claim 1 wherein said plys include a predominately black ply, a predominately amber ply and said innermost layer being predominately red. 
     
     
       3. The tire defined in claim 2 wherein said plys are solid colors. 
     
     
       4. The tire defined in claim 2 wherein said plys are striped colors. 
     
     
       5. The tire defined in claim 2 wherein said sidewall section includes a pattern thereon. 
     
     
       6. The tire defined in claim 5 wherein said sidewall pattern includes a crosshatched pattern. 
     
     
       7. The tire defined in claim 5 wherein said sidewall pattern includes a checkerboard pattern. 
     
     
       8. The tire defined in claim 5 wherein said sidewall pattern includes a striped pattern.
