Recommended Tire Inflation Pressure
The
recommended inflation pressure is not to be confused with the maximum inflation
pressure that is shown on the side of the tire. At the recommended inflation pressure,
tires will last longer and be less likely to fail, and the tow vehicle will use less fuel.
Serious injury can result from tire failure because of under inflation or overloading.
Cold Tire inflation Pressure is the tire pressure checked in the morning before you
drive more than a few miles or before rising ambient temperatures or the sun’s radiant
heat affects it. Check your tires’ air pressures at least once a month, before each trip
and each morning you drive during a trip. Tire pressure should be checked cold, as
tire pressure ratings have been designed with typical running heat/pressure build-up in
mind. Make sure the valves and caps are free of dirt and moisture.
Recommended Cold Tire Inflation Pressure
ST 225/75R-15
65 PSI
WARNING
: The maximum speed rating on the tires installed on your
trailer is 65 MPH. DO NOT EXCEED THIS RATING. Failure to heed this warning
could cause catastrophic tire failure resulting in property damage, personal
injury and/or death.
Nev-R-Lube Drums/Bearings
Dexter’s Nev-R-Lube bearings are compromised of opposed tapered roller bearing
cones sealed inside of a precision ground, one piece double cup arrangement. These
bearings are designed with a small amount of axial end play. The end play is essential
to the longevity of the bearings service life. Please read the Dexter Operation
Maintenance Service manual provided in your owner’s packet.
Bearing Inspection
1. Jack trailer at marked jack location pad behind axle on mainframe.
2. Check for excessive wheel end clearance by pulling the tire assembly towards you
and by pushing the assembly away from you. Slight end play is acceptable.
3. Rotate tire slowly forwards and backwards. The wheel assembly should turn freely
and smoothly.
4. Excessive wheel end play, restriction to rotation, noise, or “bumpy” rotation should
be remedied by replacing the bearing unit.
5. Bearing units should be inspected every year or 12,000 miles whichever comes
first.
NOTE: A slight amount of grease weeping from the seal area is normal. Excessive
leakage may indicate abnormal bearing operation.
Bearing end play inspection, drum removal/installation, and bearing replacement
procedures are described in the Dexter Operation Maintenance Manual enclosed
in you owner’s packet. Airstream recommends that these procedures are pre-
formed by a qualified Dexter service technician due the need of specialized tools
and training.
