COMPOUND APPLICATIONS:

D10A is designed for a soft, wet, tacky track condition.
D20A is slightly tougher than the D10A and works well on crumbs or marbled tracks.
D30A is slightly tougher than the D20A and is designed for loose conditions or surfaces that clean off and become dry-slick. 
The A40 is tougher than the D30A and is designed for drying track conditions that are transitioning and may lack overall grip (dusty, loose, sandy, etc.).  
The 50 compound is designed for a hard packed track that forms a high grip racing groove.
The new FK tire is designed for larger oval kart tracks that require roll speed.

SET-UP INFORMATION:

The 11.0x8.0-6 right side slicks (D10A, D20A, D30A and A40 compounds) have approximately 0.110" tread depth. This line of tires works best on short tracks that are "paperclip" or "bullring" in shape.

The 11.0x9.0-6 right side slicks (50 compound) have approximately 0.065" tread depth. This tire has been designed to maximize roll speed on larger speedway dirt tracks.

The oval kart slicks have been manufactured with a specific amount of tread depth to optimize performance, handling and longevity on a full range of track conditions.  

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.
