General Description
Tires
This vehicle is equipped with following tire.
Tire specification :
P235/60 R16 or 235/60 R16
The tires are of tubeless type. The tires are designed to operate satisfactorily with loads up to the full rated load
capacity when inflated to the recommended inflation pressure.
Correct tire pressures and driving habits have an important influence on tire life. Heavy cornering, excessively
rapid acceleration, and unnecessary sharp braking increase tire wear.
Wheels
Standard equipment wheels are following steel wheels.
Wheel specification :
16 x 7 JJ NOTE:
For the descriptions (items) not found in this section, refer to the same section of the Service Man-
ual mentioned in the FOREWORD of this manual.
All wheel fasteners are important attaching parts in that they could affect the performance of vital
parts and systems, and/or could result in major repair expense. They must be replaced with one of
the same part number or with an equivalent part if replacement becomes necessary. Do not use a
replacement part of lesser quality or substitute design. Torque values must be used as specified
during reassembly to assure proper retention of all parts.
There is to be no welding as it may result in extensive damage and weakening of the metal.

6) Install circlip (1) by using snap ring plier.
7) Apply grease to entire surface of cage.
Use joint grease in tube included in spare part.
8) Insert cage into outer race and fit circlip (1) into groove of
outer race.
9) Apply grease in tube included in spare part to inside of outer
race, and fit boot to outer race.
Fill up inside of boot with joint grease.
“A” : Joint Grease
(about 90 - 100 g (3.2 - 3.5 oz) (Black))
10) Fitting boot to outer race, adjust so that measurements “b”
and “c” become as shown in the figure.
Differential side (RH) boot installation position
(Length “b”) : 196.8 - 206.8 mm (7.75 - 8.14 in.)
Differential side (LH) boot installation position
(Length “c”) : 127.5 - 137.5 mm (5.02 - 5.41 in.)
11) Before fixing boot band, insert screwdriver into boot on joint
side and allow air to enter boot so that air pressure in boot
becomes the same as atmospheric pressure.
12) Clamp boot band. Check boots for distortion or dent.
CAUTION:
Position opening of circlip “a” so that it will not be lined
up with a ball.
