How to Mount Hoosier Kart Tires
DIRECTION OF ROTATION/ MOUNTING INSTRUCTIONS: Every Hoosier race tire has a four character alphanumeric code embossed into ONE sidewall of the tire (example: F7X2). 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 left side of the vehicle. This applies to tires without directional arrows.
On tires with directional arrows, please mount the tire onto the rim so that the tire travels in the direction of the rotational arrow. 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. Never exceed 40 psi to seat beads. 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. The max inflation pressure is 57 psi (4.0 kg/cm2). Never exceed the max inflation pressure under any circumstance.
