Can I convert from dual wheels to a super-single (wide-base) wheel?
Yes, but there are several considerations: 1) The required stud length may be different. For hub-piloted applications using 22mm 2-piece flange nuts, a minimum length is required for proper thread engagement to the nut. All ConMet trailer and drive axle hubs designed for dual wheel applications can be used with wide-base wheels. This assumes a 1/2″ brake drum thickness, 1.13″ wheel disc thickness and a 1.19″ nut height, giving a minimum required stud standout of 2.94 inches from the hub flange. A longer stud, while affecting appearance and socket fit, is also acceptable. Some available nuts include: Metform 39627 (1.06″ height) and Hayes Lemmerz 90846 (1.19″ height). For stud-piloted applications on drive and trailer hubs: All ConMet trailer and drive axle hubs designed for dual wheel applications can be used with wide-base wheels. Standard ball seat cap nuts for single or outer dual applications can be used for steel wheels. The thread size is “-16. For aluminum wide-base wheels, ConM
