Mixed commercial fleets
When maintenance spans tractor and trailer axles, list the wheel fitment by fleet segment. Record the load rating, bolt pattern and center bore for each position using the approved part drawing. The reviewer should check the lug seat and wheel stud interface whenever a supplier proposes different fastening geometry. Ask the supplier to separate compatible proposals from alternatives that need additional checks. If a wheel will be installed at several sites, nominate which bay can inspect the initial units.
