Teams must race on Sunoco Super Series approved tires only. Teams may call Sibila Race Engineering at 866-472-2464 for any information on the Sunoco Super Series approved Goodyear Racing Tires and to order practice tires if needed. Tires must be paid for on race day by cash or credit card, checks will only be accepted it the team has a credit card on file with Sibila Race Engineering prior to purchasing tires. All teams must follow the procedures listed below.

The purchasing of series specified tires will start on the day of every event ten minutes after the pit gates are officially opened. Teams will be allowed in the series tire truck by owner’s points, the highest team in the current owners points ten minutes after the pit gates have opened will go first, after that it will go by the next highest in line until all teams with owners points have gotten their tires.

Teams with no owner’s points will purchase tires in the order that the series tire officials place them in, when they report to the series tire officials.

No team is allowed to purchase additional sets of tires until every team has had the opportunity to purchase one set, unless they have called in an advance order with Sibila Race Engineering. Additional sets of tires will be purchased also by owner’s points but in reverse order. Purchased qualifying tires will be impounded at the tire purchasing area until all teams have purchased qualifying tires. Tires will be released prior to the end of practice, but more typically prior to the start of practice. Unless otherwise announced, qualifying tires can be scuffed during practice. All tires marked for that day’s events must remain in the teams pit area in full view of series officials and may never go inside a team’s trailer.

To be eligible for a top fifteen qualifying position, teams must purchase tires at the track the day of the race. Series officials must mark these tires prior to them leaving the tire mounting area. It is the responsibility of the teams to get their tires properly marked. Tires will be checked for that events mark prior to qualifying and prior to the start of the feature. Any car qualifying in the top fifteen with tires not properly marked for that event cannot start the feature better than sixteenth.

Cars must start the feature on the same tires on which they qualified. Cars running the last chance race or qualifying races may change tires prior to that race, but must return to the qualifying tires for the feature. Cars which run the last chance race on tires on which they qualified, will be allowed to use additional right side tires purchased that day for the feature. During a regular feature event tires may not be changed unless there is a legitimate flat tire, verified by an official prior to taking the tire off the car. Changes must be approved by a series official in advance.

Use of tire softening or altering agents will not be permitted. Use of such substances will result in immediate disqualification with loss of points. Series officials will routinely inspect tires after qualifying and after selected features. Series officials also reserve the right to confiscate any tire at any time for testing. If testing is done and tire has been chemically altered, team will loose all event points and monies and face possible suspension of racing penalties with the Sunoco Super Series.
