1.) All karts and microds will have their tires stenciled by EMRP at the end of their hot laps session. These karts and microds must use only the stenciled set of four tires for the remainder of competition that night (heats, LCQ, and features).
2.) After hot laps begin, the only change allowed to tires is air pressure. No tire prep is allowed after the start of hot laps.
3.) If a tire is cut in hot laps or in a heat race, the driver must prove to EMRP officials the tire is cut and will be allowed to replace it. The driver must then run a heat race equivalent number of laps on the new tire either during an intermission or with another heat race group and will also start their feature race from the rear of the field.
