Wheel Studs and Nuts
Quote:
The wheels must be securely attached with the correct number and type of nuts or bolts. Stud or bolt holes, and any locating washers, must not be expanded or elongated and all wheel and retainer tapers must match. All studs must be securely fitted and engage for at least the same thread length as provided originally by the vehicle manufacturer.
