The following is to be used as a general guide for tire inflation. It is
important that tires are inspected after unit is loaded. Do not exceed
maximum recommended tire pressure.
Wheel Torque Specification
Tire Pressure Table
It is
an
extremely important safety procedure to apply and
maintain proper wheel mounting torque on your trailer axle.
Torque wrenches are the best method to assure the proper
amount of torque is being applied to a fastener.
Wheel lugs should be torqued before first road use and after
each wheel removal. Check and re torque after the first 10
miles, 25 miles, and again at 50 miles. Check periodically
thereafter.
Note: Wheel lugs must be applied and maintained at the
proper torque levels to prevent loose wheels, broken studs,
and possible dangerous separation of wheels from your axle.
1.
Start all lugs by hand to prevent cross threading.
2. Tighten lugs in sequence, as shown in the diagram.
3. Tighten the lugs - see chart
