A WORD ABOUT "NON MARKING" POLY TIRES
All poly tires and wheels are non marking regardless of color. It is often
assumed when a black tire slides or spins the material will
leave a black mark on the floor. The coloring of poly tires is so dilute
that this is not true. Looking through a thin slice from a clean poly tire will
reveal the transparency of the material. The opaque black look of a tire is due
to the thickness of the material.
Carbon black used in black rubber tires does mark floors. Carbon black from rubber tire skid marks (as well as other marking contaminants on a floor) can be picked up by any color poly wheel or tire and remark the floor elsewhere. Non marking rubber tires contain little or no carbon black and are generally white in color. They generally also have less durability as carbon black adds to rubber tire integrity.
AVT makes "gold" colored poly tires available for the "non marking poly" market, however, you will likely find no difference in marking or durability. |
