HOIST A vehicle can be lifted with:
• A single-post, frame-contact hoist
• A twin-post, chassis hoist
• A ramp-type, drive-on hoist
When a frame-contact type hoist is used, verify
that the lifting pads are positioned properly (Fig. 8).

TOWING
RECOMMENDATIONS
When it is necessary to tow a Ram Truck, the rec
ommended method is either:
• the sling-type, rear-end raised towing method; or
• the wheel-lift towing method with a tow dolly lo
cated under the front wheels. A vehicle with flat-bed hauling equipment can also
be used to transport a disabled vehicle.

GENERAL
INFORMATION
Tires are designed for each specific vehicle. They
provide the best overall performance for normal op eration. The ride and handling characteristics match
the vehicle's requirements. With proper care they
will give excellent reliability, traction, skid resis
tance, and tread life. These tires have specific load carrying capacities. When correctly inflated, they
will operate properly.
Tires used in cool climates, and with light loads
will have a longer life than tires used in hot climates
with heavy loads. Abrasive road surfaces will accel erate tire wear.
Driving habits have more effect on tire life than
any other factor. Careful drivers will obtain much
greater mileage than careless drivers.
Driving habits that shorten the life of any tire;
• Rapid acceleration and deceleration
• Severe application of brakes • High-speed driving
• Taking turns at excessive speeds
• Striking curbs and other obstacles It is very important to follow the tire rotation in
terval
IDENTIFICATION Tire type, size, aspect ratio and speed rating are
encoded in the letters and numbers imprinted on the
side wall of the tire. Refer to the chart to decipher
the tire identification code (Fig. 1). Performance tires will have a speed rating letter
after the aspect ratio number. The speed rating is

not always printed on the tire side wall. The letter S
indicates that the tire is speed rated up to 112 mph.
• Q up to 100 mph
• T up to 118 mph
• U up to 124 mph
• H up to 130 mph
• V up to 149 mph
• Z more than 149 mph (consult the tire manufac
turer for the specific speed rating)
An All Season type tire will have either M + S, M
& S or M—S (indicating mud and snow traction) im
printed on the side wall.
RADIAL-PLY TIRES Radial-ply tires improve handling, tread life, ride
quality and decrease rolling resistance. Radial-ply tires must always be used in sets of
four. Under no circumstances should they be used on
the front only. They may be mixed with temporary spare tires when necessary, but reduced speeds are
recommended.
Radial-ply tires have the same load-carrying capac
ity as other types of tires of the same size. They use
the same recommended inflation pressures.
SPARE TIRE (TEMPORARY) The compact spare tire is designed for emergency
use only. The original tire should be repaired and re
installed at the first opportunity. Refer to Owner's
Manual for complete details.
