Abstract
A passenger car tire that combines a number of design features or parameters which yield a tire which has road noise, tread wear and handling performance characteristics which are equal to or better than those exhibited by comparable prior art tires, which possesses improvements in mud and snow performance not heretofore approached in prior art high performance tires, and in which heat dissipation characteristics are such that ornamental white sidewall lettering may be applied without in any way detracting from performance and durability characteristics. Moreover, and most surprisingly, the tire of the present invention is actually lighter in weight than is the most comparable prior art high performance tire, which does not possess the improved mud and snow characteristics of the invention.
