ment (“frame rack”), checked with three dimensional measuring equipment, and the necessary pull correc-
tions made. If damage remains in the frame beyond the area covered by this service part after the pull, the
frame must be replaced in its entirety.
1. Before proceeding with this repair procedure review the required service warnings and precautions. (Refer to 13

CAUTION: 3500 Dual rear tires have a new tire
rotation pattern. This is to accommodate the out-
lined white letter (OWL) tires. When replacing a
flat, the spare tire may have to be remounted on
the rim or installed at a different location to main-
tain the correct placement of the outlined white
letter (OWL) tires.
The recommended method of tire rotation for dual rear
wheel is. Other methods can be used, but may not
provide the same tire longevity benefits.

TIRES
DESCRIPTION
TIRES
Tires are designed and engineered for each specific vehicle. They providethe best overall performance for normal
operation. The ride and handling characteristics match the vehicle’s requirements. With proper care they will give
excellent reliability, traction,skid resistance, and tread life.
Driving habits have more effect on tire life than any other factor. Carefuldrivers will obtain in most cases, much
greater mileage than severe use or careless drivers. A few of the driving habits which will shorten the life of any tire
are:
Rapid acceleration
Severe brake applications
High speed driving
Excessive speeds on turns
Striking curbs and other obstacles
Radial-ply tires are more prone to irregular tread wear. It is important tofollow the tire rotation interval (Refer to 22
- TIRES/WHEELS - STANDARD PROCEDURE). This will help to achieve a greater tread life.
TIRE 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.
Performance tires have a speed rating letter after the
aspect ratio number. The speed rating is not always
printed on the tire sidewall. These ratings are:
Qup to 100 mph
Sup to 112 mph
Tup to 118 mph
Uup to 124 mph
Hup to 130 mph
Vup to 149 mph
Zmore than 149 mph (consult the tire manufac-
turer for the specific speed rating)
An All Season type tire will have eitherM+S,M&SorM–S(indicating mud and snow traction) imprinted on the
side wall.
TIRE CHAINS
Tire snow chains may be used oncertainmodels. Refer to the Owner’s Manual for more information.
SPARE / TEMPORARY TIRE
The temporary spare tire is designed for emergency use only. The original tire should be repaired or replaced at the
first opportunity, then reinstalled. Do not exceed speeds of 80 KMH (50 MPH). when using the temporary spare tire.
Refer to Owner’s Manual for complete details.
RADIAL – PLY TIRES
Radial-ply tires improve handling, tread life and 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. A maximum speedof80KMH(50MPH)isrec-
ommended while a temporary spare is in use.
