MICHELIN X ONE TIRE MOUNTING ® INSTRUCTIONS The MICHELIN ® ® X One tire must be mounted on 22.5 x ® 14.00" size wheels. Both steel and aluminum are available in Hub (Uni Mount) piloted, and currently aluminum is available in Stud (Ball Seat) configuration. Supplemental parts will be required with 'Stud-Piloted' wheels; i.e. front and rear outer cap nuts to replace inner and outer nuts used for mounting traditional stud-piloted dual assembly. Industry-wide part numbers will be 5995L and 5995R. To ensure proper stud length, there should be 4 threads visible from the nut. There are no differences in mount or dismount procedures other than when mounting the MICHELIN ® X One tire onto a vehicle, position the tire so ® that the tire sits on the outbound side of the wheel similar to where the outer dual would normally be positioned. Additionally, this will offer exceptional lateral clearance. Select a valve stem that can be accessed for air pressure checks and is installed facing outward. Note: Safety cages, portable and/or permanent, are also available and required for inflation of the MICHELIN X One tire assemblies. ® Incorrect Lateral Clearance 275 mm/10.9 inches is required to ensure sufficient and consistent cable contact with the shoulder/upper sidewall area (Hawkinson part # PROBE ASSEMBLY 009). It is recommended to slow the rotation speed or make several additional cycles to catch as many small punctures as possible. Shearography If using laser shearography inspection, adjust and/or modify to ensure complete imaging shoulder to shoulder, per equipment manufacturer. Also make sure the correct vacuum level is applied. Buffing ® An expandable rim width of 14.5 inches is required. The beads of the casing should be lubricated with a fast drying, non-petroleum based tire lubricant. Buffing should not start before casing reaches target pressure in the expandable rim as defined by your retread process manufacturer. Recommended minimum inflation pressure is 1.2 bars or 18 psi. Recommended tread width ranges are given below and may vary depending on the type and condition of the MICHELIN ® X One casing. The MICHELIN X One casing’s ® ® ® finished, buffed measured width should follow the same standards as other casings: no more than 2 mm less than the tread width and no more than 8 mm more than tread width. After Buff Inspection If after buffing, multiple circumferential cracks or splits remain in one or both shoulders of the tire in the vicinity of the outside tread groove (Picture 1), the casing should be rejected. This should not be confused with a 360 degree product interface line that sometimes is visible after buff (Picture 2). If this line is visible, it should be probed; and if found to be loose material, the casing should be rejected. If it is tight, continue the retread process. Correct Lateral Clearance MICHELIN X ONE TIRE REPAIR AND RETREAD ® ® While the MICHELIN X One tire may require some ® ® special equipment to handle the wider tread and casing, it does not require any special procedure to be repaired or retreaded. As with any tire, special care should be given to respect the recommendations and guidelines associated with the specific product to ensure optimum performance. Initial Inspection Inspect the MICHELIN ® X One casings as defined by ® your retread process manufacturer or industry recommended practices using appropriate equipment. When using an electronic liner inspection device, such as the Hawkinson NDT, a new wide base probe of at least 66 Section Four: MICHELIN X One Tires ® ® Picture 1 Picture 2
