Dodge 2008 DH Ram Owner's Manual page 338

336 STARTING AND OPERATING
Follow the recommended tire rotation frequency for your
type of driving found in the "Maintenance Schedules"
Section of this manual. More frequent rotation is permis-
sible if desired. The reasons for any rapid or unusual
wear should be corrected prior to rotation being per-
formed.
NOTE: On Canadian vehicles only, if your vehicle is
equipped with All-Season type tires on the front and
ON/OFF Road type tires mounted on the rear, do not use
a front-to-back rotation pattern. Instead, rotate your tires
side-to-side at the recommended intervals.
