ROARRacingLogo

US RC car governing body ROAR have announced an immediate update of their 1/10th buggy wheel rules. After banning the new style 2.4″ buggy rims back in Summer 2014 ROAR have now declared them legal for all ROAR sanctioned events such as the forthcoming Nationals. This means both the traditional 2.2″ rims as well as the new 2.4″ or 61mm diameter wheels are allowed as are the respective tyres.
