Short Course Tread Width Rule
March 29, 2011
By a unanimous vote of the ROAR Executive Committee, the rule related to the maximum width of short course class tires shall remain undefined in the class rules, which invokes rule 7.3.7 that states that the tread width may not exceed the width of the wheel. For the 1/10 Short Course 2WD and 4WD categories, the maximum wheel width is 1.65 in. (41.9mm). Tires and wheels exceeding these limits will not be legal for use in ROAR competition.
