Description and operation

Tires

Tread

The portion contacting the road surface outside the

buffer layer and tire body. It’s made of high wear-

resistant rubber. Its operation is determined by its

surface details.

Buffer layer

The fabric layer between the tread and tire body is

used to prevent the damages of tires caused by

road impacts and vibration.

Tire body

This main portion is a tire-like structure consisting

of high-strength synthetic fiber cord fabric. Since it

must maintain the tire pressure and bear all the

loads and vibrations of tires, so it must have high

fatigue-resistant properties.

Tire bead

The steel wire coil on ends of tire body, which is

covered with rubber layers and wrapped with

nylon threads. It’s used to fix the tire on the rim.

Tire tube

The most tires applied in modern vehicles are

tubeless tires.

Sidewall of tire

It’s used to protect the tire body, flexing resistant

and improve the driving comfort.

Tire hydroplaning

When the vehicle is driving on the road surface

with water at high speed, it will make the tires

unable to drive like rolling on the good road

surface, thus the tires may float on it. This is called

as tire hydroplaning.It will cause the failure of

brake, low friction force and steering failure, so

it’s very dangerous.

Standing wave

During the rotation of tires, the tread will produce

the repeated deformations and restoring torques.

However, the new deformation has been produced

and the previous deformation still exists at higher

speed, so a vibration wave will be produced on

local part of tread. The lower the tire pressure is,

the more serious its vibration wave is, especially at

high speed.

Tire rotation

As indicated in the tire performance criteria (TPC),

the numbers have been engraved in the tire side

mold near to tire size. It indicates that these

numbers include the traction force index, strength,

size and rolling resistance conforming to the

criteria. Generally speaking, each size of tire shall

have different TPC numbers.

Note: Don’t use different types of tires on the

same vehicle, e.g.radial tire and bias tire, except in

emergency cases, because the vehicle will be

seriously influenced, and it may cause the control

failure of vehicle.

Replace the original tires with the tires of the same

size, load and structure. The use of other sizes or

structures of tires will seriously influence the ride

comfort, steering properties, speedometer /

mileometer values, vehicle ground clearance, and

clearance from tire to vehicle body or chassis. But

it’s not applicable for spare tires.

It’s recommended to replace a pair of tires on the

same shaft synchronously during the renewal of

tires.

If it’s required to replace a tire, find a nearest tread

to compensate the braking coefficients.

Different producers design different tread patterns,

but the same TPC number may be used on the

same vehicle.

All season tire

Now, most of vehicles are equipped with all season

PCR tires as standard configurations. These tires

can be used as snow tires. During the use in the

snow, their average ratio is 37% higher than

friction coefficient of non-all season tires. In other

aspects, e.g.their wet water friction coefficient,

rolling resistance, tread service life and air

resistance are all improved, because the design of

tread patterns and tread compound are also

improved. These tires have “M+S” engraved

behind their tire side marked size codes. The suffix

“MS” is also engraved behind the instructions for

tire side TPC numbers.

Not all the steering wheel tires are all season tires.

These tires have no “MS” marks behind the tire

sizes or behind the instructions for TPC numbers.

Tire label

The tire labels shall be permanently affixed behind

the side door of driver’s seat, and the tires shall be

inflated as per the above tire pressure. The

maximum vehicle load, tire specifications

(including the spare tire) and inflating pressure

((including the spare tire) are described on the tire

labels.

Spare tire

This vehicle is equipped with full-size wheels and

spare tires on it.

Wheel

If any of the following cases occur to the wheels,

they must be replaced: bends, indentions, flanging

or deflected jumps, air leakage of weld joints,

enlargement of bolt holes, or fixing failure or

serious rusting of bolts. The jumps of wheel

transition will cause the vibration of vehicle. Any

replaced wheel must have the same load, diameter,

rim width, offset distance and mounting size as

those of original wheel. The inconformity of wheel

size or type will influence the service life of wheel

High-speed driving Low-speed driving

Wheels and tires 2C-4

and bearing, cooling of brake, readings of

speedometer/kilometer, vehicle ground clearance,

and clearance from tire to vehicle body and chassis.

Tire pressure

The recommended air pressure of any vehicle tire

shall be carefully calculated, which will give your

driving/ride comfort, good steering ability, extend

the service life of tire, and ensure its loading

capacity.

Check the tire every 5,000km. The tire pressure

must be checked every month or before driving it

for long distance. The tire must be checked at low

temperature, i.e. when the vehicle drives for about

3 minutes or at less than 1. 6km/hour. Inflate the

tire as per the air pressure indicated in the tire label

on driver’s seat side door. The inflation pressure of

tire has been given in “Instructions for Tire

Specifications and Inflation Pressure” of this

section.

The inflating valve must have a nut cap on it,

which is used to prevent the dust and water from

entering into it.

The air pressure above the recommended pressure

will lead to:

● Harder ride and driving

● Explosion or damages of tire

● Rapid wears of tread in the middle of tire

The air pressure below the recommended pressure

will lead to:

● Large noises while turning

● Difficult steering

● Rapid or uneven wears of both sides of tire

● Scratches or cutting of tire edges

● Fracture of tire cord

At higher tire temperature, its different tire

pressure on the same shaft will lead to:

● Uneven braking force

● Heavy steering

● Reduction of handling stability

● Sudden steering during the acceleration

● Direction of torque control

Tire rotation

Front and rear tires have different functions and

will lead to uneven wears, which is determined by

road surfaces for driving and different driving

habits,etc. The wear rate of front wheel tire is

below that of rear wheel tire.

In order to avoid uneven wears of tire and extend

its service life, rotate the tire every 10,000km.

After rotating the tire, adjust its air pressure, and

ensure that the torque of hub nut meets the

specified requirements.

Minimum pattern depth

1.6mm(0.06 inch)

Wheel balance

It’s a simple process to check the wheel balance. If

the wheel jumps at high speed, it shall be first

checked by you. During the replacement of wheels

and tires, their balances must be checked.

While checking the wheel balance, be sure to

follow the rules below:

① The number of balance blocks shall not

exceed two on inner or outer side of one

wheel;

② The total weight of one wheel balance block

shall not exceed 100g (3.5 ounce);

Diagnostic data and procedures

Tire wears

① Check the depth of tire pattern.

② If the depth of its pattern is below the given

value, please replace the tire.

It can be seen from the specifications that the tire

must be replaced when the depth of tire pattern is

reduced (below 1. 6mm (0. 06 inch)).

Repair instructions

Wheel repair instructions

I. Sequence of removal

① Remove the hub nut;

② Lift the wheel stably.

Note: don’t loosen the tightened wheel by heating

it. It will shorten the service life of wheel, hub nut

and wheel bearing. Excessive force application, e.g.

hitting the wheel or tire, will also cause the

damages, which can’t be recovered. It’s allowed to

hit the sides of wheel slightly with a hand or

rubber hammer.

③ Remove the wheel.

If it’s difficult to remove the wheel from the

vehicle, it may be caused by the existence of

sundries or excessive close fit among the wheel

middle holes, nuts and hubs. At this time, the

wheel can be removed from the vehicle by

adopting the following methods:

A. Re-tighten any influenced hub nut, and then

turn the hub nut two circles in its loosening

direction.

B. Lower the vehicle, try to shake the vehicle,

and adopt the weight of one or several

persons to loosen the wheel.

C. Lift up the vehicle again, and then remove the

wheel.

Note: don’t apply the lubricating oil to vertical

surface of wheel and hub (or brake disc), because

the existence of lubricating oil in these positions

will lead to the wheel loosening when the vehicle

is driven, control failure of vehicle and even

serious accidents. The lubricating oil is not good

for removal of tightened wheel. If the lubricating

oil is required, don’t apply too much oil, and only

to the centerhole area of wheel.

II. Sequence of installation

Note: before installing the wheel, please remove

the sundries from the mounting faces of wheel,

brake drum and hub with a hairbrush. If the surface

contact is poor during the installation, it will

loosen the hub nut. While the vehicle is driving,

there may be a risk of disengaging the wheel from

the vehicle. The hub nut must be tightened as per

the specified torque, but its tightening force shall

not be excessive, thus the bends of wheel, brake

drum or hub can be avoided.

① Install the wheel.

② Install the hub nuts in diagonal order. Don’t

tighten the hub nut.

③ Lower the vehicle.

④ Tighten it.

Tighten the hub nuts up to the torque of 100 to 120

N.m (73.3 to 88.3 lb-ft).

⑤ Wheel balance

Measure the balance of wheel with an automatic

balancing machine. The balancing machine is

convenient in operation, its static and dynamic

balance can be also measured. Unlike the balance

of vehicle, don’t calibrate the unbalance of vehicle,

brake drum or hub. This defect can be resolved by

precision. During the balancing work, make the

taper part through the wheel center hole to fix the

wheel, and don’t do so through the mounting hole

of hub nut.

⑥ Calibrate the unbalanced tire.

Provide two methods to calibrate the unbalanced

Wheels and tires 2C-7

tire.

One method is to fix the tire through this automatic

device, and then hit small yellow rubber blocks on

both sides of tire tread. Such calibration method is

usually permanent.

If it’s well handled, it won’t influence its

appearance or tire service life.

It’s not recommended to calibrate any tire with a

blade-shape machine, because it can reduce the

service life of tire tread, and the tire can’t be

permanently calibrated.

The other method is to remove the tire, and then

turn it by 180ﹾ on the rim. The unbalance of wheel

or tire must be known before doing so, because

this method can ensure the balance of its assembly.

⑦ Installation of tire and wheel

The tire and wheel shall be installed in the

assembling workshop. During the installation,

install them by aligning the radial hard point or

heavy balancing point of tire to the radial dot or

light balancing point of wheel.

The heavy balancing point of tire is marked with a

red dot during the start of its production, or marked

on the tire side with a label.

The light balancing point of wheel is located at the

inflating valve.

Before installing the tire and wheel, scribe a line

on the tire and inflating valve to ensure that they

can be installed in the same position during the re-

installation.

The quality of spare tire and original tire shall be

the same, and their heavy and light points shall be

marked with the same method.
