2019 RAM CHASSIS CAB tires

SERVICING AND MAINTENANCE 469
Treadwear
The Treadwear grade is a comparative rating, based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and one-half
times as well on the government course as a tire graded
100. The relative performance of tires depends upon the
actual conditions of their use, however, and may depart
significantly from the norm due to variations in driving
habits, service practices, and differences in road charac -
teristics and climate.
Traction Grades
The Traction grades, from highest to lowest, are AA, A, B,
and C. These grades represent the tire's ability to stop on
wet pavement, as measured under controlled conditions
on specified government test surfaces of asphalt and
concrete. A tire marked C may have poor traction perfor -
mance. Temperature Grades
The Temperature grades are A (the highest), B, and C,
representing the tire's resistance to the generation of heat
and its ability to dissipate heat, when tested under
controlled conditions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the material of the
tire to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The grade C
corresponds to a level of performance, which all
passenger vehicle tires must meet under the Federal
Motor Vehicle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the laboratory
test wheel, than the minimum required by law. WARNING!
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or peak
traction characteristics.

TECHNICAL SPECIFICATIONS 477
Torque Specifications
**Use only your authorized dealer recommended lug nuts/
bolts and clean or remove any dirt or oil before tightening.
Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles.
NOTE:
Dual wheels are flat mounted, center piloted. The lug nuts
are a two-piece assembly. When the tires are being rotated or
replaced, clean these lug nuts and add two drops of oil at the
interface between the hex and the washer. Ensure that the
socket is fully engaged on the lug nut/bolt (do not insert it
half way). Oil Interface Location
Do not oil wheel studs. For chrome wheels, do not substitute
with chrome plated wheel nuts.Lug Nut/Bolt

When the vehicle is shifted out of REVERSE (with camera delay turned OFF), the rear camera mode is exited and the navi -
gation or audio screen appears again. When the vehicle is shifted out of REVERSE (with camera delay turned ON), the rear
view image with dynamic grid lines will be displayed for up to ten seconds after shifting out of REVERSE unless the forward
vehicle speed exceeds 8 mph (12 km/h), the transmission is shifted into PARK or the ignition is switched to the OFF position.

Guidelines — If Equipped On Off
NOTE:
The “Forward Facing Camera Guidelines” feature is an off-road type of feature that shows the path of the tires based on the
steering wheel input.

NOTE:
The “ParkView Backup Camera Delay” setting determines whether or not the screen will display the rear view image with
dynamic grid lines for up to ten seconds after the vehicle is shifted out of REVERSE. This delay will be canceled if the
vehicle’s speed exceeds 8 mph (13 km/h), the transmission is shifted into PARK, or the ignition is switched to the OFF posi -
tion.
Active Parkview Backup
Camera Guidelines On Off
NOTE:
The “ParkView Backup Camera Active Guide Lines” feature overlays the Rear Backup Camera image with active, or
dynamic, grid lines to help illustrate the width of the vehicle and its project back up path, based on the steering wheel posi -
tion when the option is checked. A dashed center line overlay indicates the center of the vehicle to assist with parking or
aligning to a hitch/receiver.
