Yokohama signs 2-year sponsorship pact with IMSA

Chalk up another victory for Yokohama Tire Corporation's environmentally-sensitive orange oil-infused race tires.

Thanks to a new two-year sponsorship extension between Yokohama and the International Motor Sports Association (IMSA) that was announced today in Sebring, Florida, Yokohama's ADVAN ENV-R2 race slicks will continue to be the official tire of the Patrón GT3 Challenge by Yokohama.

The agreement, which runs through the 2012 season, means all Porsche 911 GT3 cars in the popular series will be competing on the revolutionary tire that uses orange oil and natural rubber to reduce the amount of petroleum in the tire.
