NASCAR said late Friday that they would look at the rules concerning the amount of lug nuts placed on tires during pit stops. This season crews have used fewer than five lug nuts on a tire in order to speed up pit stops and gain a competitive advantage on the track. While no wheels have come off during a race, several drivers have been forced to pit again with loose wheels, negating any advantage.
Earlier this week Tony Stewart criticized NASCAR for not enforcing a rule that requires crewmembers to put all five lug nuts on a wheel during a pit stop. He characterized the issue as one of safety.
“I guarantee you that envelope is going to keep getting pushed until somebody gets hurt,” Stewart said.
