WHEEL SYSTEMS STEEL VS ALUMINUM Depending on the vehicle’s vocation, a customer may choose steel wheels over aluminum. However, a 14.00 x 22.5" aluminum wheel is up to 68 lbs. lighter than its steel counterpart. Due to the larger drop center of the aluminum wheel, it is typically easier to mount the MICHELIN ® X One tire on aluminum wheels. ® STUD PILOTED WHEELS There are aluminum and steel wheels with 2" outset currently available in stud piloted configuration. Stud piloted disc wheels are designed to be centered by the nuts on the studs. The seating action of ball seat nuts in the ball seat holes centers the wheel. Fasteners with left hand threads are used on the left side of the vehicle and those with right threads are used on the right side of the vehicle. CAUTION: Do not use the 5995 nut on steel stud piloted wheels, as the shoulder will protrude past the disc face. From left to right: Aluminum MICHELIN X One tire fastener, steel or aluminum MICHELIN X One tire fastener, and steel MICHELIN X One tire fastener. ® ® ® ® See application chart on Page 8 for part numbers and more information. HUB PILOTED WHEELS Both aluminum and steel wheels are currently available in hub piloted configuration. Hub piloted disc wheels are designed to center on the hub at the center hole or bore of the wheel. The wheel center hole locates the wheel on pilots built into the hub. Hub piloted wheels use the same 2-piece flange nut as duals that contact the disc face around the bolt hole. Only one nut on each stud is used. Hub piloted wheels have straight bolt holes with no ball seat. SPECIAL FASTENERS It is necessary to order “cap nuts” to replace the inner and outer nuts that are used when mounting a traditional stud piloted dual assembly. These parts can be ordered from a wheel distributor in your area. The part numbers are listed on Page 8. A 50/50 split of left and right hand threads will be required. ® ® 6 Tire and Wheel Nomenclature
