LAKEVILLE, IN (January 11, 2007) -- Hoosier is proud to introduce the new D20A and D40A, which will replace the existing D20 and D40 in all dirt specs for Quarter Midgets and Karts. The D20A has maintained the same hardness as the D20, but has improved grip while the D40A has been softened down to a hardness of 55-57 to improve firing. Both compounds have shown considerable improvement in lap times.  

The D20A is comparable to the Burris SS-22 and is designed for cool tracks that are sandy, dusty or marbled. The D40A is comparable to the Maxxis HT-3 and works well on tracks that form a groove and start to become abrasive.  

The new D20A and D40A are available in the following tire sizes:
