===Lug nuts and wheel studs vs. bolts===
On vehicles with [[wheel stud]]s, wheels must be fitted with the correct type of [[lug nut]]s.<ref name="auto">{{cite web|title=Wheel Tech: Proper Lug Nuts or Lug Bolts|work=tirerack.com|url=https://www.tirerack.com/wheels/tech/techpage.jsp?techid=102}}</ref> On vehicles without wheel studs, wheels must be fitted with the correct type of [[lug bolt]]s.

Lug nuts (or bolts) will have either flat, tapered (conical), or ball (radius) seats. The type of seat a wheel requires will determine the appropriate lug nuts required to securely attach the wheel to the vehicle. A flat seat type has a flat end that puts pressure on the wheel and compress it against the mounting hub. Similarly, tapered and ball seat types have a conical or semicircular end, respectively. A place to find the lug nut type is to check OEM (Original Equipment Manufacturer) specifications if you have stock wheels or contact the wheel manufacturer if you have aftermarket wheels.<ref name="auto"/>

Some aftermarket wheels will only fit smaller lug nuts, or not allow an ordinary lug nut to be [[Torque wrench|properly torqued down]] because a socket will not fit into the lug hole. Tuner lug nuts were created to solve this problem by utilizing a special key to allow removal and installation with standard lug wrench or socket. The design of tuner lug nuts can range from bit style to multisided or spline drive, and are sometimes lightweight for performance purposes.

Another variation of lug nut is the "locking wheel nut", which is used as a theft prevention method to keep thieves from stealing a vehicle's wheels. When utilizing locking wheel nuts, one standard lug nut on each wheel is replaced with a nut that requires a unique key (typically a computer-designed, rounded star shape) to fit and remove the nut. This ensures that at least one lug nut will remain attached and, in theory, should prevent theft. However, universal removal tools are available which grip the head of the locking nut using a hardened left-hand thread. The success of locking wheel nuts depends on the determination of the would-be thief and the tools that they have available to them.
