Tire Rules for 2008

In the spirit of a "loose dirt" oval the tires that are allowed for the 2008 racing season will be limited to Street treaded tires and Mini-Pins. No aggressive pins will be allowed. Surface maintenance and upkeep is a difficult task and aggressive pins lead to excessive surface wear. If you think your tires might be illegal to run just ask. Preferred tires are Proline Holeshots or something of that pin size.

Nitro Rules:
~Nitro Sprint, EDM, and 2WD Late model .12 or .15 or .18 cubic inch engines only.
~ Nitro Truck class .12 or .15 or .18 motor, or the stock .18 that came with your RTR kit.
~ The Traxxas Jato 3.3 engine is legal for Nitro Truck ONLY.
~ Max fuel tank size is UNLIMITED in all classes.
~ No stinger modifications and no pipes with adjustable stingers allowed.
~ Single speed transmissions only. (A 2-speed locked into one gear is ok).
~ Two wheel/rear wheel drive only.
~ Minimum weight is 56oz.
