SUPER KART SPECS

CROSS REFERENCE CHART:   

COMPOUND APPLICATIONS:

The R45 is a soft, high traction compound desired for high performance applications. It is designed for low grip tracks that are less abrasive and require a significant amount of grip. 

The R60A is a medium compound that balances traction, durability and performance with versatility. The R60A designed for medium grip, mildly abrasive track conditions.  

The R60 is a hard compound that is designed to maximize durability on very abrasive tracks without sacrificing mechanical grip. 

SET-UP INFORMATION:

R45

The recommended starting pressure for the R45 is 11-13 psi cold. These pressures could be +/-1 psi depending on track condition. 

R60A &R60

The recommended starting pressure for the R60A and R60 is 12-14 psi cold. These pressures could be +/-1-2 psi depending on track condition. 

5.0/10.5-6 Front & 7.1/11.0-6 Rear, or 8.0/11.0-6 Rear

These tires have been designed to provide more overall grip for karting’s most demanding class – Super Karts. The front tires maximize grip on slow speed corners and allow the driver to “fine tune” rear end grip for optimum performance through high speed corners. The 5.0/10.5-6 will measure approximately 33 1/8” on a 6x6 wheel at 12 psi cold. The 7.1/11.0-6 is approximately 35” on a 6x8 wheel at 12 psi cold and the 8.0/11.0-6 is approximately 35 1/2” on a 6x8.5 wheel at 12 psi cold. A combination of these tires can be used on B-Stock and Formula 125 classes. PLEASE NOTE: Hoosier recommends using a 6x6 wheel with the 5.0/10.5-6 for best results.

DIRECTION OF ROTATION/ MOUNTING INSTRUCTIONS:

Every Hoosier race tire has a four character serial code embossed into ONE sidewall of the tire (example: J7B9). The left side tires should be mounted with the serial side code facing toward the outside of the kart. The right side tires should be mounted with the serial code facing toward the centerline 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.

Tires with directional arrows should be mounted so that the tire travels in the direction of the arrow.
