Today on Twitter, Musk tweeted that Roadster 2's wheels will only have one center nut. In his next tweet, he clarified that the nut will be quite large.
My favorite is one in tension, other DoF in compression. New Roadster wheels will only have one nut.— Elon Musk (@elonmusk) August 18, 2020
Yes, it will have huge nuts haha— Elon Musk (@elonmusk) August 19, 2020
A centerlock wheel is a type of car wheel for which there is one nut in the center of the rim, instead of the more common ring of 4 or 5 nuts or bolts.
The centerlock wheel and hub system was first introduced by Rudge-Whitworth in the early 1900s, for use in car wire wheels. Initially called "QD" (for "quickly disconnectable") the basic mechanism for "knock-off" style centerlock hubs was patented by 1908. It was quickly adopted by auto manufacturers and racers.
Wheels of this type are used on many modern racing cars, including NASCAR, Formula One and racing sports cars.
The use of a single-center nut allows for greater room between the wheel and wheel hub. This extra space can be used to add larger brake disks and calipers. Once again, this is a significant benefit for sports cars and race cars alike because they increase the stopping power.
As an all-electric supercar, Roadster maximizes the potential of aerodynamic engineering — with record-setting performance and efficiency. The car reaches speeds from 0 to 60 mph in a record 1.9 seconds, making it the fastest production car in the world. Therefore, wheels with one central nut are an excellent addition to the Roadster 2.0.
