SPRINT / ROAD RACE KART TIRES

CROSS REFERENCE CHART:   

COMPOUND APPLICATIONS:

The R50 is a soft, high traction compound designed for high performance applications. It is designed for tracks that are less abrasive and require a significant amount of grip. 

The R60 is a medium-hard compound that balances traction, durability and performance with versatility. The R60 is designed for medium grip, high heat track conditions. The R60 will have less grip than the R50.   

SET-UP INFORMATION:

R50

The recommended starting pressure for the R50 is 9-11 psi cold. These pressures could be +/-1 psi depending on track condition. This compound has been designed for sprint or solo applications.

R60

The recommended starting pressure for the R60 is 11-13 psi cold. These pressures could be +/-1-2 psi depending on track condition. The 22350 (7.1/11.0-5) rear is designed for sprint and road race applications. The 22400 (7.1/11.0-5 "S") is designed for road race applications. The "S" stands for stiff side wall construction. This tire is designed for karts that need less grip in the rear of the kart.

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 must be mounted with the serial code side located toward the outside of the kart. The right side tires should have 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. 

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