DIRT QUARTER MIDGET SPECS

CROSS REFERENCE CHART:   

COMPOUND APPLICATIONS:

D10 is designed for a soft, wet, tacky track condition.
D20A is slightly tougher than the D10 and works well on crumbs or marbled tracks.
D30 is tougher than the D20A and performs well on cleaned off, dry-slick tracks.
Indoor Surfaces: 
The D20A will work well on cars that are easy on tires (i.e. Rookie, Jr. Honda) or on smooth indoor tracks that are not abrasive.
Because the D30 is slightly tougher than the D20A, it will be better on a wider spectrum of classes early in the indoor season. 
Midway through the indoor season as the track gains grip and becomes more abrasive, it's recommended to switch to a Hoosier A35 or A40A asphalt compound. 

SET-UP INFORMATION:

Recommended starting pressure is contingent upon track condition and compound selection. 
The typical starting pressure on both dirt and indoor tracks is between 5-7 psi (cold) on the left side and 7-9 psi on the right side.

DIRECTION OF ROTATION/ MOUNTING INSTRUCTIONS:

Every Hoosier race tire has a four character serial code embossed into ONE sidewall of the tire (example: J7B9). This is not referring to the tire's bar code. To be consistent when mounting from set to set, the tire should be placed on the rim so that the serial code faces towards the infield of the track. Before seating the beads, we recommend placing the tire inside a mounting ring and adjusting the ring to fit snug around the tire. We highly advise using the mounting ring as we believe not using it can over stretch the carcass leading to inconsistent sizing. Once the tire has seated onto the rim, it is important the tire be initially stretched to about 10 psi over cold starting pressure to get the tire to its proper "profile". The tire should be set at this pressure for a few minutes and then dropped to the desired race pressure. Just be consistent in this procedure to get repeatable results. The asphalt/dirt quarter midget tires can be flipped or reversed on the wheel to provide even wear.
