DIRT OVAL KART TIRES

CROSS REFERENCE CHART:   

COMPOUND APPLICATIONS:

Cool or Soft track conditions: 
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.

The D10, D20A and D30 have a softer overall tire construction. 

Hot or Hard track conditions:
RD30 is designed for tracks that are dusty, loose and lack grip.
RD35 will have more available grip compared to the RD30 and will work on the same track conditions.
D40A is designed for a medium hard track condition that forms a groove and becomes black.
D60 is designed for hard, abrasive tracks that take rubber and require grip.

The RD30, RD35, D40A and D60 have a stiffer overall tire construction.

SET-UP INFORMATION:

The Hoosier dirt oval kart slicks have an approximate tread depth of .080".
The 11.0x8.1-6 tires will measure approximately 34" on a 10" wide wheel with 8 psi.
The 11.0x6.0-6 will measure approximately 33" on a 8.5" wide wheel with 6 psi.
The 10.5x4.5-6 will measure approximately 32.5" on a 6.5" wide wheel with 6 psi.
Recommended starting pressure is contingent upon track conditions and compound selection.
The D10, D20A & D30 can range between 5-8 psi, while the RD30, RD35, D40A & D60 may be between 7-10 psi. 

DIRECTION OF ROTATION/ MOUNTING INSTRUCTIONS:

Mount the tire onto the rim with the white "HOOSIER" logo facing toward the outside of the kart. Once the tire is on the rim, 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 dirt oval kart slicks can be flipped or reversed on the wheel to provide even wear.
