EXAMPLE:
Size Designation: P = Passenger car tire size based on U.S. design standards
 ....blank.... = Passenger car tire based on European design standards
LT = Light Truck tire based on U.S. design standards
T = Temporary Spare tire
31 = Overall Diameter in Inches (in)
215 = Section Width in Milimeters (mm)
65 = Aspect Ratio in Percent (%)
—Ratio of section height to section width of tire.
10.5 = Section Width in Inches (in)
R = Construction Code
— Rmeans Radial Construction.
— D means Diagonal or Bias Construction.
15 = Rim Diameter in Inches (in)
214 STARTING AND OPERATING

Proper operation of four wheel drive vehicles depends on
tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.
Because four wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.

To help avoid personal injury, follow these tips:
•Never reach through the steering wheel to operate
steering column controls. Injury to your hands or
loss of vehicle control may result.
•If the engine stalls or power assist fails due to a
malfunction, vehicle steering and braking will
require greater effort.Significant over or under-inflation of tires, or mixing
sizes of tires or wheels on the vehicle can lead to loss
of braking effectiveness.

may result in false speedometer and odometer read-
