the same design and tread as the other tires on the vehicle.
Differences in design and tread in some instances result in
unequal rolling radii. If tires do not have the same outside
diameter within one-half inch, excessive tread scuffing
will result. When selecting a replacement tire, select one
having an outside diameter that matches within one-half
inch the outside diameter of the other tires on the vehicle,
particularly on the same axle. Measure the outside
diameter of the tires with a conventional tire measuring
gage.
(2) Periodic T i r e Rotation. Tires should be
inspected for evenness of wear and be measured, as
described in (1) above, after every 2,000 miles of vehicle
operation. At this time, based on the results of inspection
and measurements, if uneven wear is indicated, proceed
to rotate the tires around.
NOTE
Refer to TM 9-2610-200-20 for proper tire
rotation procedures.
