The 31.0/4.5-5 will measure approximately 31” on a 5x5 wheel at 8 psi. Compounds available in this size include D10, D20A, RD40, & A35. Please refer to the ‘Dirt QM’ page for dirt compound applications. The 32.0/4.5-5 will measure approximately 32” on a 5x5 wheel at 8 psi. Compounds available in this size include D10, D20A, RD40, & A35. Please refer to the ‘Dirt QM’ page for dirt compound applications. The 4.5/10.0-5 will measure approximately 31 ¾ on a 5x5 wheel at 8 psi. This tire has a stiffer construction that provides more grip for higher powered classes that utilize a locked LR hub on their car. The compounds available include R60A (medium), and R60 (hard). The R60A is designed to work in the same conditions as the A35 compound. The R60 is designed to keep the car free on high heat, high traction surfaces. For further information, please visit the ‘Sprint/RR Kart’ page. |

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. The A35 NY1 tires have directional arrows and should be mounted so that the tire travels in the direction of the arrow. Tires can be flipped after running to provide even wear. |
