the certification label. However, they should never exceed the tire
limitation for load or air pressure. If you discover that your tires cannot
support the actual weights, the load will need to be lightened.
NOTE:
Tires are warranted by the manufacturer of their respective brand
and are to be serviced and warranted by a service center. Contact your
dealer for information on service centers for tires.
How to Change a Tire
1. Place blocking under main rail of frame with hydraulic jack on
top of blocking in front of front spring hanger, ALWAYS on main
rail.
2. Break lug nuts loose before raising coach. DO NOT REMOVE
lug nuts.
3. Raise coach with jack, until wheel is off the ground.
4. Place additional blocking under frame for security support. DO
NOT depend fully on jack.
5. Be sure coach is solid and will not move with wheel and tire off.
6. Remove lug nuts when tire is off the ground.
7. Replace with spare tire and wheel onto hub.
8. Reinstall lug nuts and tighten firmly.
9. Drop tire and wheel onto ground after removing supports.
10. Now fully tighten and torque lug nuts at 90 to 120 pounds.
11. Place all equipment into coach or tow vehicle.
12. Re-torque lug nuts after traveling 100 miles.
Wheel Bearings
ALL wheel bearings are pre-lubricated during assembly of axle and
brakes.
Your coach may have “ULTRA LUBE”, a method of having a grease fitting
in the end of the axle. Remove rubber cap on the end of axle and using
a standard grease gun, you may place 6 to 8 shots of grease into the
bearings, (if you forgot to repack bearings), before leaving on a trip. Don’t
forget to correctly repack bearings as per maintenance manual when you
return home, using wheel bearing grease.
Wheel Lugs
When the wheels are installed on your recreational vehicle, the lug nuts
must be tightened at 90-120 foot pounds of torque. Powder coat painted
wheels may require more torque attempts due to thickness of paint. You
must re-torque the wheel lugs at 50 and 200 miles. A decal on the wheel
may require checking torque earlier.
After your first trip, check the wheel lugs periodically for safety. The wheel
lugs should then be checked after winter storage, before starting a trip or
following extensive braking. The size of bolt head or nuts is 13/16 inch
standard and 3/4” for chrome nut.
Over torqueing will damage
components, especially if torque wheel lugs goes over 150 pounds.
