NOTE
Consult the Mercedes-Benz Sprinter Operators
manual for extensive wheel tightening and wheel
torque procedures, cautions, and warnings.
WARNING
For safety reasons, the wheel tightening torque
must be checked immediately after changing a tire
and again after 30 miles to 140 ft-lbs. The wheels
could otherwise come loose.
Tire Rotation
Front and rear tires perform different jobs and can wear
differently depending on the types of roads driven,
driving habits, etc� To obtain the longest tire life, you
should inspect and rotate your tires regularly�
Many automotive dealers and tire dealers will perform
a free tire inspection to look for uneven or abnormal tire
wear�
Tires should be rotated every 6,000 to 8,000 miles�
For the longest tire life, any time irregular wear is seen
have the tires checked, alignment checked, and tires
rotated by your truck or tire dealer� Have the cause of
uneven wear corrected�
NOTE
Tires with black urethane coated wheels will
require tires to be dismounted and remounted so
as to leave rims in original locations because the
coating is only applied to one side.
