4. Place a Hydraulic Jack on the frame close to the spring hanger. Raise the trailer until
the tire clears the ground. NEVER attempt to use a stabilizer jack to lift the RV.
5. Set up a Jack Stand under the frame just to the rear of the tire being changed, then
change your tire.
6. Follow the Wheel Nut Torque instructions provided in
on page
Wheel Nut Torque
Torque is the amount of rotating force applied to a fastener, such as a lug nut. The axle and
wheel assemblies of your RV are designed differently than those on your car. The over-
all size, weight and center of gravity subject the wheels to pressures unique to trailering.
During normal cornering, the tires and wheels experience a considerable amount of stress
called side-load. Therefore, the lug nuts on your RV frequently require torque maintenance.
• ALWAYS use a properly calibrated torque wrench to confirm proper torque.
• ALWAYS check lug nut torque on each wheel before departure, regardless of how short
the trip may be.
• DO NOT allow under-torque or over-torque on any wheel.
• Tighten the lugs in the correct order for your RV's lug pattern shown in the diagram be-
low.

Find your RV's wheel size on the table below. Tightening the lugs should be done in three
stages. Determine the correct torque for each stage, and use the torque sequence shown.
