Even wear across the
center with worn strips
around the shoulder.
Excessive wear
extended across the
entire shoulder rib to
a major tread groove.
Circumferential
wear along the rib
edges next to major
tread grooves.
Tread ribs worn so that
one side is higher,
resulting in step-offs
across the tread.
Typical of a radial
ply rib type.
Rotation.
Measure and align
all wheels. If wear is
severe, rotate tires.
Characteristic of slow
wear rate of radial tires
on free rolling axles.
Scrubbing due to
incorrect alignment,
front and/or rear
defective suspension or
steering components.
Scrubbing due to a rear
axle misalignment.
This wear should not be
a concern unless the
wear becomes too deep.
Tires can be rotated to
drive axles at this point.
Replace worn parts,
align vehicle, and if
wear patterns are
severe, rotate tires.

Description Appearance Possible Cause Solution
Shoulder step wear
Full shoulder wear
Erosion/river
channel/wear
Feathered or
sawtoothed wear
Over-inflation wear
Excessive wear in the
center of the tread –
when properly inflated,
the tire appears to cup
when viewed across
the tread face.
Over-inflation
expands the tire
forcing more wear in
the center of the tread.
Keep tires properly
inflated.
