1. Once spotty wear develops in tread due to hard 

braking or abrupt starting, localized wear tends to 
be promoted.

Removal

1. Loosen wheel lug nut by approximately 180

°

 (half a 

rotation), then raise the vehicle and remove the 
nuts.

2. Remove wheel and tire.

NOTE:  Never use heat to loosen a tight wheel lug nut.   
The application of heat to the hub can shorten the life of 
the wheel and may cause damage to wheel bearings.

Installation

1. Install wheel and tire.

2. Install wheel lug nut, and lower the vehicle. Tighten 

the wheel lug nuts to the specified torque in 
numerical order.

Torque: 118N·m (12.0kg·m/87 lbft)

CAUTION:  Before installing wheels,  remove any 
build-up of corrosion on the wheel mounting 
surface and brake disc mounting surface by 
scraping and wire brushing.   Installing wheels 
without good metal-to-metal contact at mounting 
surfaces can cause wheel nuts to loosen,  which 
can later allow a wheel to come off while the vehicle 
is moving.

NOTE:  Valve caps should be on the valve stems to 
keep dust and water out.

WHEEL AND TIRE SYSTEM

Tire

Tire Replacement

When replacement is necessary, the original metric the 
size should be used.   Most metric tire sizes do not have 
exact corresponding alphanumeric tire sizes.   It is 
recommended that new tires be installed in pairs on the 
same axle.   If necessary to replace only one tire, it 
should be paired with tire having the most tread, to 
equalize braking traction.

CAUTION:  Do not mix different types of tires such 
as radial, bias and bias-belted tires except in 
emergencies,  because vehicle handling may be 
seriously affected and may result in loss of control.

Tire Dismounting

Remove valve cap on valve step and deflate the tire. 
Then use a tire changing machine to mount or dismount 
tires.
Follow the equipment manufacturer's instruction.  Do 
not use hand tools or tire lever alone to change tires as 
they may  damage the tire beads or wheel rim.

Tire Mounting

Rim bead seats should be cleaned with a wire brush or 
coarse steel wool to remove lubricants,  and light rust. 
Before mounting a tire, the bead area should be well 
lubricated with an approved tire lubricant.
After mounting, inflate the tire to 200kPa (2.0kg/cm

2

, 28 

psi) so that beads are completely seated.   Inflate the air 
to specified pressure and install valve cap to the stem.

WARNING:  NEVER STAND OVER TIRE WHEN 
INFLATING. BEAD MAY BREAK WHEN BEAD 
SNAPS OVER RIM'S SAFETY HUMP AND CAUSE 
SERIOUS PERSONAL INJURY.
NEVER EXCEED 240 KPA (2.4kg/cm

2

, 35 PSI) 

PRESSURE WHEN INFLATING. IF 240 KPA (2.4kg/
cm

2

, 35 PSI) PRESSURE WILL NOT SEAT BEADS, 

DEFLATE, RE-LUBRICATE AND RE-INFLATE.  OVER 
INFLATION MAY CAUSE THE BEAD TO BREAK AND 
CAUSE SERIOUS PERSONAL INJURY.

Tire Repair

There are many different materials on the market used 
to repair tires.
Manufacturers have published detailed instructions on 
how and when to repair tires.   These instructions can 
be obtained from the tire manufacturer if they are not 
included with the repair kit.

Wheel Inspection

Damaged wheels and wheels with excessive run-out 
must be replaced.
Wheel run out at rim (Base on hub Bore):

480RS012

General Balance Procedure

Deposits of mud, etc. must be cleaned from the inside of 
the rim.
The tire should be inspected for the following: match 
mount paint marks, bent rims, bulges, irregular tire 
wear, proper wheel size and inflation pressure.   Then 
balance according to the equipment manufacturer's 
recommendations.
There are two types of wheel and tire balance.
Static balance is the equal distribution of weight around 
the wheel.
Assemblies that are statically unbalanced cause a 
bouncing action called tramp. This condition will 
eventually cause uneven tire wear.
