3. Tires, wheels, studs
(Note: This is an NER Supplemental Rule. If NER hosts a National or divisional-level event, studs
are governed by the National RallyCross Rules)
3.1. Studded tires are permitted in all classes at all events unless a site owner specifies studs
not be used. Studs must be DOT legal and properly installed into tires with
manufacturer’s stud holes. No self-drilled tires, homemade studs or specialty ice racing
type cleats allowed.
3.2 Oversized studs are not permitted. Stud size must be the length specified for the tire by
the tire manufacturer.
3.3 It is the vehicle owner’s responsibility to know and obey public laws which apply to
studded tire usage seasons, with regard to traveling on studded tires to and from an
event.”
