Note

Please observe the various differing legal requirements regarding tyres.

General information

•

New tyres do not offer optimal grip at first and should therefore be run in for

about 500 km at a moderate speed and an appropriately cautious style of driving.

You will also profit from longer tyre life.

Tyre life

•

The tread depth of new tyres may differ because of design features and the

configuration of the tread (depending on the type of tyre and the manufacturer).

Drive over curbs on the side of the road and other such obstacles slowly and,

where possible, at a right angle in order to avoid damage to tyres and wheel trims.

Inspect your tyres from time to time for damage (punctures, cuts, splits and

bulges). Remove foreign bodies from the tyre profile.

Damage to tyres and wheels is frequently not visible. Unusual vibrations or

pulling of the vehicle to one side could be a sign of tyre damage. Please reduce

your speed immediately and stop if you suspect that a wheel is damaged.

Inspect the tyres for signs of damage (bulges, splits, etc.). If no visible damage is

present, please drive at an appropriately slow speed and carefully to the nearest

specialist garage in order to have your vehicle inspected.

The life of your tyres very much depends on the following points:

•

Also protect your tyres from contact with oil, grease and fuel.

Tyre pressure

Immediately replace any dust caps of the valves which have got lost.

Mark wheels before removing them so that their previous direction of running

can be maintained when mounted them again.

The working life of tyres will be shortened considerably if the tyres are insufficiently

or over-inflated and this will have an adverse effect on the handling of your vehicle.

Correctly inflated tyres are of particular importance when travelling at high speeds.

It is therefore good to check the pressure at least once a month and also before

setting off on a long trip. Please do not forget the spare wheel when checking the

tyres.

•

Always store wheels or tyres which been removed in a cool, dry and, where

possible, dark place. Tyres which are not fixed to a wheel trim should be stored

upright.

The tyre inflation pressures for summer tyres are indicated on the inside of the fuel

filler flap ⇒ fig. 215. The inflation pressures for winter tyres are 20 kPa (0.2 bar)

higher than those for summer tyres ⇒ page 236.

WARNING

•

New tyres during the first 500 km do not offer optimal grip and should

therefore be run appropriately - risk of accident!

Never drive with damaged tyres - risk of accident!

The tyre pressure should be at the highest pressure specified for your vehicle at all

times.

•

Wheels and Tyres 233

The tyre inflation pressure of the emergency spare wheel R 18 is 420 kPa (4.2 bar).

Wear indicators

Always check the inflation pressure of tyres when cold. Do not reduce the higher

pressure of warm tyres. Adapt the inflation pressure of the tyres accordingly if your

vehicle is carrying a significantly higher payload.

Driving style

Fast cornering, sharp acceleration and braking (squealing tyres) increase wear-and-

tear on your tyres.

Balancing wheels

The wheels of a new vehicle are balanced. There are a wide range of influences

when driving which may result in an imbalance and which makes themselves felt

through vibration in the steering.

Fig. 216 Tyre tread with wear

indicators

You should have the wheels rebalanced since any imbalance increases wear-and-

tear on the steering, the suspension and tyres. A wheel must also be rebalanced

when a new tyre is fitted and each time a tyre is repaired.

The base of the tread of the original tyres has wear indicators 1.6 mm high, installed

at right angles to the direction of travel. These wear indicators are located at 6 - 8

points depending on the make and are evenly spaced around the circumference of

the tyre ⇒ fig. 216. Markings on the walls of the tyres through the letters “TWI”,

triangular symbols or other symbols identify the position of the wear indicators.

Wheel alignment errors

Incorrect wheel alignment at the front and rear will not only increase wear-and-tear

on the tyres but will also has an adverse effect on vehicle safety. Contact your

specialist garage if you notice any unusual tyre wear.

A remaining tread of just 1.6 mm, measured in the grooves of the tread next to the

wear indicators, means that your tyres have reached their legally permissible

minimum tread depth.

WARNING

•

If the inflation pressure is too low, the tyre must perform a greater flexing

work. At higher speeds the tyre will warm up as a result of this. This can

result in tread separation and even a tyre blowout.

•

You must have your tyres replaced with new ones at the latest when the

wear indicators have been worn down. The legally permissible minimum

tread depth should be observed.

•

Immediately replace the damaged rims or tyres.

Tyres which are 6 years old or more should only be fitted in exceptional

Worn tyres do not provide the necessary adhesion to the road surface at

high speeds on wet roads. One could experience “aquaplaning” (uncon-

trolled movements of the vehicle - “swimming” on a wet road surface).

cases and when adopting an appropriately cautious style of driving.

For the sake of the environment

Tyres which are insufficiently inflated increase your fuel consumption.

Changing wheels around

We recommend that you have any work relating to tyres or wheels carried out by a

specialist garage. Your dealer has all of the necessary special tools and replace-

ment parts available plus the required specialist knowledge and is also in a position

to properly dispose of the old tyres. A large number of specialist garages also have

an attractive range of tyres and wheels available.

The tyre/wheel combinations which are approved for your vehicle are indicated in

your vehicle documents. Approval and licensing may differ according to the legis-

lation prevailing in individual countries.

Proper knowledge of the tyre data makes it easier for you to select the correct type

of tyre. Tyres do, for example, have the following inscription on their walls:

What this means is:

If significantly greater wear is present on the front tyres, we recommend changing

the front wheels around with the rear wheels as shown in the diagram ⇒ fig. 217.

You will then obtain approximately the same life for all the tyres.

Any spare wheel which differs from the tyres fitted to the vehicle (e.g. winter tyres

or low-profile tyres) should only be used only for a short time in the event of a

puncture and when adopting an appropriately cautious style of driving. It should be

replaced as quickly as possible by a normal wheel.

Wheel bolts

Wheels and wheel bolts are matched to each other in terms of design. Each time

you fit other wheels - e.g. light alloy wheels or wheels with winter tyres - you must

therefore also use the matching wheel bolts of the correct length and shape of

Winter tyres

WARNING

The handling of your vehicle will be significantly improved when driving on wintry

roads if you fit winter tyres. Summer tyres do not offer the same grip on ice, snow

and at temperatures below 7 °C because of their construction (width, rubber blend,

tread pattern). This particularly applies to vehicles which are equipped with low-

profile tyres or high-speed tyres (code index H or V on wall of tyre).

You must on no account drive your car at more than the permissible

maximum speed for your winter tyres - risk of an accident resulting from

tyre damage and loss of control over your car.

For the sake of the environment

Winter tyres must be mounted on all four wheels to obtain the best handling char-

acteristics.

Fit your summer tyres on again in good time since summer tyres offer you better

grip and handling on roads which are free of snow and ice as well as ar tempera-

tures below 7 °C - the braking distance is shorter, there is less tyre noise, tyre wear

is reduced and fuel consumption is reduced.

You must only fit those types of winter tyre which are approved for your vehicle. The

permissible sizes of winter tyres are stated in your vehicle documents. Approvals

may differ because of national legislation.

Please remember that the tyres should be inflated to 20 kPa (0.2 bar) more than is

the case for summer tyres ⇒ page 232.

Note

Please observe the various differing legal requirements regarding tyres.

Winter tyres no longer offer the same winter performance once the tyre tread has

worn down to a depth of about 4 mm.

Unidirectional tyres*

Ageing also causes winter tyres to lose most of their winter performance properties

- even in cases where the remaining tread depth is still clearly more than 4 mm.

The direction of rotation of the tyres is marked by arrows on the wall of the tyre.

This indicates the direction of rotation of the tyre, and it is essential that the tyres

are fitted on to run in this direction. Only then are the tyres able to provide the

optimal properties in terms of grip, low noise, wear-and-tear and aquaplaning.

Speed restrictions apply to winter tyres as well as to summer tyres ⇒ page 234,

⇒

.

You can fit winter tyres of a lower speed category to your vehicle provided that you

also do not drive faster than the permissible maximum speed for such tyres, even

if the possible maximum speed of your vehicle is higher. The corresponding tyre

category can damage the tyres when exceeding the permissible maximum speed.

Should it be necessary to fit on a spare wheel in exceptional cases with a tyre not

dedicated to the running direction or in opposite running direction, please adopt a

cautious style of driving as the tyre is no longer able to provide optimal grip and

handling in such a situation. This particularly important on wet roads. Please refer

to the notes ⇒ page 243, “Spare wheel*”.

Please pay attention to the notes if you decide to fit winter tyres ⇒ page 232.

You can also fit so-called “all-year tyres” instead of winter tyres.

You should have the defective tyre replaced as soon as possible and restore the

correct direction of rotation on all tyres

Please contact your specialist garage if there are any points which are not clear who

will be able to provide you with information regarding the maximum speed for your

tyres.

Snow chains

Snow chains must only be mounted on the front wheels.

Wheels and Tyres 237

When driving on wintry roads, snow chains improve not only traction, but also the

braking performance.

For technical reasons, it is only permissible to fit snow chains with the following

wheel/tyre combinations:

Only fit snow chains with links and locks not larger than 12 mm.

Remove the full wheel trims if you wish to fit snow chains to the wheels.

Observe the national legal requirements relating to the maximum vehicle speed

with snow chains.

WARNING

Please pay attention to the information in the supplied fitting instructions of

the snow chain manufacturer.

Caution

You must take the chains off as soon as you drive on roads which are free of snow.

They adversely affect the handling of your vehicle, damage the tyres and are rapidly

destroyed.

Note

We recommend that you use snow chains from the Škoda genuine accessories.
