When trailer tires show signs of scuffing,
feather-edging or uneven wear, examine the trailer
for damaged suspension (frame, shocks, linkage,
etc.), axle, wheel bearings and wheels. Proper
wheel alignment and wheel bearing adjustment is
essential for proper tire wear. The simplest form of
checking wheel alignment “toe” is by running the
trailer over a “SCUFF GAUGE”. A scuff gauge
reading of 16 feet or less per mile is considered
satisfactory. If a scuff gauge is not readily avail-
able, or edge wear on one side of a tire is occur-
ring signifying positive or negative camber, align-
ment can be checked as follows:
