2. Make sure of proper tire pressure before towing trailer The tightness of the wheel nuts or bolts is very important in keeping the wheels properly seated to the hub Before each tow check to make sure they are tight Metal creep between the wheel rim and wheel nuts or bolts may cause rim to loosen Death or injury can occur if wheel comes off Tighten lug nuts or bolts before each tow The proper tightness torque for wheel nuts or bolts and tightening sequence is listed in the Inspection Service and Maintenance section of this manual Use a torque wrench to tighten the lug nuts and use the crisscross star pattern sequence Improper tightening of the lug nuts voids the axle warranty Wheel nuts or bolts are also prone to loosen after first being assembled When driving a new trailer or after wheels have been remounted check to make sure they are tight after the first 10 25 and 50 miles of driving and before each tow thereafter Failure to perform this check can result in a wheel separating from the trailer and a crash leading to death or serious injury Wheel nuts or bolts are prone to loosen after being first assembled Death or serious injury can result Check wheel nuts or bolts for tightness on a new trailer and after re mounting a wheel at 10 25 and 50 miles Inadequate wheel nut or bolt torque can cause a wheel to separate from the trailer leading to death or serious injury Verify wheel nuts
