2012 SKODA OCTAVIA wheel size

Always check the inflation pressure when the tyres are cold. Do not reduce the
higher pressure of warm tyres.
With greater payload, adjust the tyre inflation pressure accordingly.
Driving style
Fast cornering, sharp acceleration and braking increase the wear of your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. When driving, there are a wide range
of influences which may result in an imbalance. This may make itself felt by a vi-
bration in the steering.
Have the wheels rebalanced after replacing the tyres.
Wheel alignment errors
An incorrect wheel alignment at the front or rear leads to excess wear on the tyres.
Tyre damage
Drive over curbs and other such obstacles slowly and, where possible, at a right
angle in order to avoid damage to tyres and wheel trims.
We recommend checking your tyres and wheel rims for damage (punctures, cuts,
splits and bulges, etc.) on a regular basis. Remove foreign bodies (e.g. small
stones) from the tyre profile immediately.
Changing wheels around
If significantly greater wear is present on the front tyres, we recommend chang-
ing the front wheels around with the rear wheels as shown in the dia- gram » Fig. 156 . You will then obtain approximately the same life for all the tyres.
We recommend that you change the tyres around every 10 000 km in order to
achieve even wear on all tyres and to obtain optimal tyre life.
Storing tyres
Mark them previously used tyres so that you are able to fit them on again to run in the same direction.
Always store wheels or tyres in a cool, dry and, where possible, dark place. Tyres which are not fixed to a wheel trim should be stored upright.
Wear indicators
The base of the tread of the tyres has 1.6 mm high wear indicators installed.
These wear indicators are located multiple times depending on the make and are evenly spaced around the circumference of the tyre » Fig. 155 – 
. Markings on
the walls of the tyres through the letters “TWI”, triangular symbols or other sym-
bols identify the position of the wear indicators.
New tyres and wheels
First read and observe the introductory information and safety warn-
ings
on page 181.
Only fit radial tyres of the same type, size (rolling circumference) and the same
tread pattern on one axle on all 4 wheels.
The tyre/wheel combinations which are approved for your vehicle are indicated in
your vehicle documents.
Where possible replace tyres by axle. Always fit the tyres with the deeper tread
depth to the front wheels.

While pressing the button, the warning light  lights up. At the same time the
system memory is erased and the new calibration is started, which is confirmed
with an audible signal and then the warning light  goes out.
If the warning light  does not go out after the calibration, this indicates a sys-
tem fault. Seek help from a ŠKODA specialist garage.
The rolling circumference of the tyre can change if: › the tyre inflation pressure is too low;
› the structure of the tyre is damaged;
› the vehicle is loaded on one side;
› the wheels of an axle are loaded heavily (e.g. when towing a trailer or when
driving uphill or downhill);
› snow chains are mounted;
› the spare wheel is mounted;
› one wheel per axle was changed.WARNING■
When the warning light  illuminates, immediately reduce the speed and
avoid sudden steering and brake manoeuvres. Stop the vehicle as soon as
possible and inspect the tyres and their inflation pressure.■
Under certain circumstances (e.g. sporty style of driving, wintry or unpaved
roads) the warning light  can be delayed or does not light up at all.

Wheel bolts
First read and observe the introductory information and safety warn-ings
on page 181.
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
also use the matching wheel bolts of the correct length and shape of spherical cap. This is essential to ensure that the wheels are tightly fitted and that the
brake system operates properly.

Winter tyres
First read and observe the introductory information and safety warn-
ings
on page 181.
The handling of your vehicle will be significantly improved when driving on wintry roads if you fit winter tyres. Summer tyres on ice, snee and at temperatures be-
low 7 °C have less grip. This is especially true of low-profile tyres or high-speed
tyres .
To achieve the best possible handling properties, winter tyres must be fitted on
all 4 wheels, the minimum tread depth must be 4 mm and tyres must be no older than 4 years.
Winter tyres of a lower speed category can be used provided that the permissible
maximum speed of these tyres is not exceeded even if the possible maximum
speed of the vehicle is higher.
The winter tyres speed limit is set in the menu » operating instructions for Info-
tainment , chapter Setting vehicle systems (CAR button) .
For the sake of the environment
Fit the summer tyres on again in good time as they provide better handling prop-
erties, a shorter braking distance, less tyre noise, and reduced tyre wear on roadswhich are free of snow and ice as well as at temperatures above 7 °C. The fuelconsumption is also lower.
Snow chains
First read and observe the introductory information and safety warn-
ings
on page 181.
When driving on wintry roads, snow chains improve not only traction, but also the
braking performance.
Snow chains must only be mounted on the front wheels.
For technical reasons, it is only permissible to fit snow chains with the following wheel/tyre combinations.

Remove the full wheel trims before installing the snow chains. 

ings on page 189.
The anti-theft wheel bolts can only be removed/tightended with the aid of the
adapter » page 188 , Vehicle tool kit .

Pull off the full wheel trim from the wheel rim or the cap from the anti-theft
wheel bolt.
›
Insert the adapter

until the stop so that only the outer hexagon is
jutting out.
›
Push the wheel wrench onto the adapter

up to the stop.
›
Loosen or tighten the wheel bolt » page 191.
›
After removing the adapter, reinstall the full wheel trim or place the cap onto
the anti-theft wheel bolt.
›
Have the tightening torque checked with a torque wrench as soon as possible.
Make a note of the code number hammered into the rear side of the adapter or
the rear side of the anti-theft wheel bolt. This number can be used to purchase a
replacement adapter from a ŠKODA Partner, if necessary.
We recommend that you always carry the adapter for the wheel bolts with you in
the vehicle. It should be stowed in the vehicle tool kit.

The repair can be undertaken on the vehicle immediately. Performing a repair with the breakdown kit not at all intended to replace a per-
manent repair on the tyre. Its purpose is to get to the nearest ŠKODA specialist
garage.
Use the breakdown kit to reliably repair tyre damage caused by foreign bodies or
a puncture with diameters up to approx. 4 mm.
Do not remove foreign bodies , e.g. screws or nails, from the tyre!
The breakdown kit must not be used under the following circumstances: › if there is damage to the wheels;
› in outside temperatures of less than -20 °C;
› with tears or punctures greater than 4 mm in size;
› if there is damage to the tyre wall;
› when driving with very low tyre pressure or with a completely flat tyre;
› if the use-by-date (see inflation bottle) has passed.
WARNING■
A tyre filled with sealant has the same driving characteristics as a standard
tyre.■
Do not travel faster than 80 km/h.
■
Avoid accelerating at full throttle, sharp braking and fast cornering.
■
Check the tyre inflation pressure after driving for 10 minutes!
■
The sealant is hazardous to heath. Remove immediately if it comes into con-
tact with the skin.
For the sake of the environment
Used sealant or sealant whose expiry date has passed must be disposed of in ac- cordance with environmental protection regulations. 192Do-it-yourself
