From Knoxville Raceway
Knoxville, IA (April 8, 2013) – Hoosier Tire has released the following information concerning the tires that will be used at Knoxville Raceway this season:
Pressure Recommendations
The following is the recommended minimum starting air pressures for the new sprint dirt spec tires:
– Left Rear (all sizes in H12 and H15) – 6 psi
– Right Rear (105/16-15 H15, H20, and Medium) – 8.5 psi
Tire and Bead Lock Fitment
Hoosier Racing Tire Corp is recommending teams consult with their specific wheel manufacturer to ensure that new and correct bead lock rings are being utilized with Hoosier Dirt Sprint Car Tires. Over a period of time from usage, bead lock rings can become distorted possibly resulting in a loss of air pressure in the tire.
In addition teams should consult with their wheel manufacturer for installation instructions and torque specifications for bead lock rings designed for sprint car dirt racing.
Knoxville Raceway Tire Rules
Knoxville Raceway tire rules are posted in the 2013 rules on the web site for all classes at http://www.knoxvilleraceway.
Knoxville Raceway will start out the season with the one tire rule for all night in the 410 class. The 410’s will also be given a courtesy tire to be used at any time during the season. This is a one time exemption and may be a new legal tire. Officials must be notified when using this one time exemption. Officials will keep track of this for the teams. The courtesy lap procedure has been changed to one lap for flat tires only in all events.
