Tire Vibration - Holiday Admiral 2016 Manual

NOTE:
It is normal for tires to heat up and
inflation pressure to increase during
travel. If the motorhome must be
driven to get air, check and record
the tire pressure first then add the
proportional amount of pressure so
when the tires cool, inflation pressure
will be correct.
Remove the cap from the valve stem.
z
Firmly press the tire gauge onto the
z
valve stem and record reading.
Add air to achieve recommended
z
inflation pressure.
If the tire is overinflated, release air by
z
pushing on the metal stem in the center
of the valve then recheck the pressure.
Replace the valve stem cap.
z
Repeat with each tire.
z
Inspect all the tires for nails or other
z
objects that could be embedded or
puncture the tire and cause a leak.
Check the sidewalls for gouges, cuts,
z
bulges, or other irregularities.
NOTE:
Air pressure in a tire increases (warm
weather) or decreases (cold weather)
one to two pounds for every 10° F. of
temperature change.

Tire Vibration

Sudden tire failure is often preceded by tire
vibration. Symptoms that can cause tire failure
are a bulge in the sidewall or swelling in the
tire carcass. Striking an object or large hole in
the road surface can damage a tire.
Inspect the tires periodically thereafter
as rotational forces can continue to stress
damaged areas and later manifest in tire
failure. If an unusual vibration begins or a
bulge is noticed in the sidewall, have the tires
evaluated by a qualified professional as soon
as possible.
Tire Rotation
Tire rotation can increase the useful life of
the tires by achieving uniform wear on all of
the tires. Have the tire manufacturer determine
the rotation pattern. The first tire rotation is the
most important in determining which rotation
pattern to use. Any unusual or unique wear
patterns, or indications of uneven wear that
may have developed, should be evaluated for
possible tire rotation. Misalignment, imbalance
or other mechanical problems may exist and
will need to be corrected prior to rotation.
Tire Replacement
As represented within the tire manufacturer's
published tire data guide, the size and
rated load carrying capacity of the original
equipment tires on your motorhome meet
or exceed the motorhome's maximum axle
weight/load ratings. Criteria used to determine
when tire replacement is necessary are road
hazard damage, wear, and age.
Tire replacement based on wear is
determined by either measuring the tire's
groove depth or a visual inspection of wear
bars. Replace tires when the groove depth is
2/32" or less on rear tires and 4/32" or less on
front tires.

Tire groove depth gauge
Wear bars are raised areas cast into the
groove of the tire. Replace the tire when the
wear bar in the groove is even (preferably
before) with the road surface contact patch.
A worn out tire cannot adequately channel
water through the groove, which will result
in hydroplaning. The tire manufacturer
determines tire replacement based on age.
While ozone inhibitors in the rubber help
extend the life expectancy of a tire, exposure
to the elements slowly breaks down the
rubber, which can then suddenly fail when put
to use. Tires that are five to seven years old
(depending upon environment) are considered
age worn and need to be replaced for safety
even though the tire may not outwardly show
age weathering and still has considerable tread.
Replacement tires on any axle, must be of
the same manufacturer brand, model, size, and
load range and must have a load rated carrying
capacity equal to or greater than the original
equipment tires.
