The controversial practice of not using all five lug nuts on a tire during a NASCAR sanctioned event ended Monday. NASCAR updated its rulebook Monday and will require teams to install all five lug nuts on a tire used on a racing vehicle in its top touring series.
In a memo sent to teams Monday afternoon, the sanctioning body told the organizations that they will be expected to have all five lug nuts installed in a safe and secure manner throughout all national series events. Scott Miller, NASCAR Senior Vice President of Competition issued an official statement as part of the announced change:
“NASCAR has been closely monitoring the aggressive strategies on pit road. Safety is an area we do not take lightly, as our record has clearly indicated. It’s important for us to have a system in place immediately for addressing lug nut installation, while we also work alongside the industry to develop the best long-term solution.”
