Chains
If you
need tire chains, install them on
both sides of each driving axle.
CAUTION
Chains on the tires of only one tandem
axle can damage the driveline U-joints
and the interaxle differential. Your re
-
pairs could be costly and time-con-
suming.
Speed Restricted Tires
WARNING!
This vehicle may be equipped with
speed restricted tires. Check each
tire’s sidewall for maximum rated
speed. The vehicle should not be op
-
erated at sustained speed in excess
of maximum rated speed. Failure to
comply with these speed restrictions
could cause sudden tire failure which
can result in death, personal injury or
property damage.
