Low profile tyres

Wheels

Low profile tyres have a wider tread, a larger

wheel diameter and a lower sidewall height.

Therefore, its driving behaviour is more agile.

Wheels and tyres

Low profile tyres may deteriorate more quick-

ly than standard tyres, for instance due to

strong knocks, potholes, manhole covers and

kerbs. Correct tyre pressure is very important

General notes

You may also notice that the engine runs at a

slightly faster idling speed when necessary.

This is quite normal, and no cause for con-

cern. The increased idling speed allows the

alternator to meet the greater power require-

ment and charge the battery at the same

time.

When driving with new tyres, be especially

careful during the first 500 km (300 miles).

page 347.

›››

If you have to drive over a kerb or similar

obstacle, drive very slowly and as near as

possible at a right angle to the obstacle.

To avoid damage to tyres and wheels, drive

with special care when driving on roads in

poor condition.

–

Check from time to time if the tyres are

damaged (punctures, cuts, cracks or

dents). Remove any foreign objects em-

bedded in the treads.

Visually check your wheels every 3000 km.

If the tyres or rims have received a heavy im-

pact or have been damaged, have a special-

ised workshop check whether or not it is nec-

essary to change the tyre.

–

Damaged wheels and tyres must be re-

placed immediately.

Low profile tyres may deteriorate more quick-

ly than standard tyres.

–

Keep grease, oil and fuel off the tyres.

Replace any missing valve caps as soon as

possible.

Concealed damage

–

Mark the wheels before taking them off so

that they rotate in the same direction when

put back.

Damage to tyres and rims is often not readily

visible. If you notice unusual vibration or the

car pulling to one side, this may indicate

that one of the tyres is damaged. Reduce

speed immediately if there is any reason to

suspect that damage may have occurred. In-

spect the tyres for damage. If no external

damage is visible, drive slowly and carefully

to the nearest specialised workshop and

have the car inspected.

When removed, the wheels or tyres should

be stored in a cool, dry and preferably dark

place.

New wheels and tyres

It is best to have all wheels and tyres serviced

by a specialised workshop. There they have

the required knowledge, the special tools and

the corresponding spare parts.

wraps around the foreign body and provision-

ally seals the tyre.

An arrow on the tyre sidewall indicates the di-

ways note the direction of rotation indicated

when mounting the wheel. This makes sure

that optimal use is made of tyre properties in

terms of aquaplaning, grip, excessive noise

and wear.

●

All four wheels must be fitted with tyres of

the same type, size (rolling circumference)

and, if possible, tread pattern.

Some manufacturers use the letters “ZR” for

tyres with a maximum authorised speed

above 240 km/h (149 mph).

ice and snow accumulating on the inside.

This should be taken into account, depend-

ing on the driving situations, as snow or ice

accumulated in the wheels can cause vi-

bration in the vehicle when it drives at over

40 km/h. It is advisable to remove ice and

snow from the inside of the wheels using

hot water.

●

Use only combinations of tyres and rims,

as well as suitable wheel nuts, approved by

SEAT. Otherwise the vehicle may be dam-

aged, causing an accident.

If the type of spare wheel is different form the

normal wheels — e.g. in the case of winter

tyres or particularly wide tyres — the spare

wheel should only be used temporarily in the

event of a puncture, and the vehicle should

be driven with care. Refit the normal road

wheel as soon as possible.

For technical reasons it is not possible to

use wheels of other vehicles; in some cases

not even wheels from the same vehicle

model should be used.

selecting replacement tyres, do not rely

entirely on the nominal tyre size marked on

the tyre, since the nominal tyre size can dif-

fer significantly depending on the manu-

facturer. Lack of clearance can damage

the tyres or the vehicle and, as a result, en-

danger road safety. Risk of accident!

In vehicles with four-wheel drive, the 4 wheels

must be fitted with tyres of the same brand,

type and tread so that the traction system is

not damaged by a difference in the number

of turns of the wheels. Therefore, in the event

of a puncture, only a spare wheel with the

same perimeter as normal tyres should be

used.

Unbalanced wheels should be rebalanced,

as they otherwise cause excessive wear on

also be rebalanced when a new tyre is fitted

or if a tyre is repaired.

Insufficient or excessive pressure greatly re-

duces the useful life of the tyres and adverse-

ly affects vehicle performance and ride. Cor-

rect inflation pressures are very important,

especially at high speeds.

Incorrect wheel alignment

Incorrect running gear alignment causes ex-

cessive tyre wear, impairing the safety of the

vehicle. If you notice excessive tyre wear, you

should check wheel alignment at a SEAT Of-

ficial Service.

The tyre pressure must be adjusted accord-

ing to the load the vehicle is carrying. If the

vehicle is going to carry the maximum load,

the tyre pressure should be increased to the

maximum value indicated on the sticker

Correct inflation pressures and sensible driv-

ing habits will increase the useful life of your

tyres.

WARNING

Do not forget the spare wheel when checking

the tyre pressures: Keep this spare wheel in-

flated to the highest pressure required for the

road wheels.

Unsuitable handling of the wheels and

tyres may lead to sudden tyre pressure los-

ses, to tread separation or even to a blow-

out.

●

Check tyre pressure at least once a month,

and also prior to any long trip.

The tyre pressure should only be checked

In the case of a minimised temporary spare

Only use winter tyres of the correct type ap-

proved for your vehicle. The sizes of these

tyres are specified in the vehicle's documents

(e.g. EC Certificate of Conformity or COC¹⁾).

The vehicle documentation varies depending

on the country of residence.

Wheel nuts

The wheel nuts are matched to the rims.

When installing different wheels (for instance

alloy wheels or wheels with winter tyres) it is

important to use the correct wheel nuts with

the right length and correctly shaped bolt

heads. This ensures that wheels are fitted se-

curely and that the brake system functions

correctly.

Winter tyres

Winter tyres lose a great deal of their proper-

ties when the tread is worn down to a depth

of 4 mm.

–

Winter tyres must be fitted on all four

wheels.

Only use winter tyres that are approved for

your vehicle.

The performance of winter tyres is also se-

verely impaired by ageing, even if the tread is

still much deeper than 4 mm.

Please note that the maximum permissible

speed for winter tyres may be lower than

for summer tyres.

The wheel nuts must be clean and turn easily.

WARNING

Snow chains will improve braking ability as

well as traction in winter conditions.

Exceeding the maximum speed permitted

for the winter tyres fitted on your car can

cause tyre failure, resulting in a loss of con-

trol of the vehicle – risk of accident.

WARNING

The use of unsuitable or incorrectly fitted

chains could lead to serious accidents and

damage.

For technical reasons snow chains may only

be used with the following wheel rim/tyre

combination.

●

Always the appropriate snow chains.

For the sake of the environment

Observe the fitting instructions provided

by the snow chain manufacturer.

When winter is over, change back to sum-

mer tyres at an appropriate moment. In

temperatures above +7°C (+45°F), perform-

ance will be improved if summer tyres are

used. Fuel consumption, wear and noises

while driving will all be reduced.

●

Never exceed the maximum permitted

speeds when driving with snow chains.

CAUTION

●

Remove the snow chains to drive on

roads without snow. Otherwise they will im-

pair vehicle handling, damage the tyres

and wear out very quickly.
