1. 01Reading the DOT CodeWeek and year of manufacture.
2. 02InflationCold, monthly, and before every trip.
3. 03Replacement Wheels & Lug TorqueMatch capacity, offset, and contour.
4. 04Wheel Torque SequenceThree stages in a star pattern.
5. 05Select Compatible Tires and WheelsMatch replacement wheels and tires to the hub, load requirements, original offset, and approved rim configuration.
6. 06Prepare and Remove a Wheel SafelyUse stable preparation, frame support, and controlled parts handling when removing a trailer wheel.
7. 07Read the Correct Torque SpecificationSelect wheel torque by matching every relevant chart detail rather than choosing a value from wheel diameter alone.
8. 08Install, Torque, and Recheck Wheel FastenersStart fasteners by hand, tighten in the prescribed sequence and stages, and complete the applicable torque rechecks.
9. 09Recognize Tire Wear PatternsUse tread wear patterns to identify the pressure, loading, alignment, balance, or braking checks indicated by the source chart.
10. 10Check Loading and Tires Before TravelCombine load-rating checks, level loading, tire inspection, and lug-fastener verification before towing.
