Cupping
Cups or scalloped dips appearing around the
edge of the tread on one side or the other al-
most always indicate worn (sometimes bent)
suspension parts. Adjustment of wheel align-
ment alone will seldom cure the problem. Any
worn component that connects the wheel to
the trailer (wheel bearings, springs, bushings,
etc.) can cause this condition. Worn compo-
nents should be adjusted or replaced with
new ones. The worn tire should be balanced
One side wear
In instances where an inner or outer rib wears
faster than the rest of the tire, there may be
a need for a realignment of the tires. This
occurs when there is excessive camber in
the axle, causing the wheel to lean too much
to the inside or outside and putting too much
load on one side of the tire. The trailer may
simply need the wheels aligned, but mis-
alignment could be due to sagging springs,
overloaded trailer or an unbalanced load on
multi-axle trailers. Because load has a great
eect on alignment, be sure the trailer is load-
ed to balance the weight on the axle or axles.
Trailers should be towed with the trailer level,
this is particularly important with independent
suspension trailers using torsion axles.
the bottom) is at fault. Tire inflation pressure
should always be checked with a reliable tire
gauge. Occasionally, this wear pattern can re-
sult from extremely wide tires on narrow rims.
In such situations, tires or wheels will have to
be replaced.
Underinflation
This is the most common problem in trailer
tires. This type of wear usually results from
consistent underinflation. When a tire is under
inflated, there is too much contact with the
road by the outer treads, which wear prema-
turely. Tire pressure should be checked with a
reliable pressure gauge.
Feathering
Feathering is a condition when the edge of
each tread rib develops a slightly rounded
edge on one side and a sharp edge on the
other. By running your hand over the tire, you
can usually feel the sharper edges before
you’ll be able to see them. The most common
cause of feathering is incorrect toe-in setting.
If this is occurring, have the toe-in adjusted to
a proper setting.
