· The tires must always have adequate pressure for the  
vehicle's state of load ÿ p. 342.  
· New tires have to be run in as they initially have reduced grip

drive during the first 600 km (370 miles) with due caution.  
· Before setting off, always inflate all tires to the correct  
pressure ÿ p. 342.  
· Regularly check the pressure of the tires when they are  
cold and always maintain the prescribed values. If the  
pressure is too low, the tire could get so hot while driving  
that the hard tread could detach and the tire burst.  
· If you drive with too low pressure, the tire is subjected to  
more bending work and, therefore, it could get so hot that

and check the wheels and tires for damage.  
Introduction to the topic  
· To reduce the risk of loss of control of the vehicle, accident,  
or serious injury, never loosen the bolted joints on rims  
with bolt-on rims.  
Tires are the most stressed vehicle components and,  
in turn, the most underestimated. However, they are  
very important, since their narrow support surfaces are  
the vehicle's only contact with the road.  
· Do not use used wheels or tires without knowing their history.  
Used wheels and tires may be damaged, sometimes  
inconspicuously, which could cause tire damage, failure  
and loss of control of the vehicle.  
The useful life of the tires depends on their pressure,  
their handling and their correct mounting, as well as  
the driving style.  
WARNING  
· Old tires, even if they have never been used, can suddenly  
lose air or blow out (particularly at high speed) and cause  
accidents and serious injuries. If a tire has more than  
New tires and old, worn or damaged tires have a

Avoid damage to rims and tires  
WARNING  
— If you climb any curb or other low obstacles,  
always do it slowly and at a right angle so that both front  
wheels touch the obstacle at the same time.  
Missing or improperly tightened wheel bolts could cause  
the wheel to come loose, resulting in loss of vehicle control,  
an accident and serious injury.  
— Check tire pressure regularly.  
Never ride with missing wheel bolts or  
with them loose  
— Regularly check the tires for damage, e.g. g., holes, cuts,  
punctures, blisters, etc.  
· Only use wheel bolts that are suitable for the rim  
and the type of vehicle in question.  
— Never exceed the load capacity or maximum speed of the  
tires ÿ p. 346.  
· Always tighten the wheel bolts with the correct tightening  
torque. If you do not have a torque wrench, tighten the  
wheel bolts with the wheel wrench, go immediately to the  
nearest specialized workshop and have the tightening  
torque checked.

Tires over 6 years old  
Tires age due to physical and chemical processes, which can  
affect their function. Tires stored for a long time without being  
used age sooner than tires that are used continuously.  
Volkswagen recommends having tires that are older than 6  
years replaced with new ones. This also applies to tires that  
can apparently continue to be used and whose profile has not  
yet reached the legally prescribed minimum value ÿ .  
Fig. 241 Schematic representation: diagram for  
exchanging the wheels.  
Likewise, winter or all-season tires lose a large part of their  
properties with age, regardless of the depth of the profile they  
still have.

harmonized.

In order for all tires to wear evenly, it is advisable to

on rims upright.

— When you have new tires fitted, drive the first 600 km (370  
miles) with special caution, as they still have to be broken  
in. Tires that have not been broken in have reduced grip ÿ

— Replace tires at least per axle ÿ — Replace old tires  
only with tires approved by Volkswagen for the type of

WARNING  
The wheels have to have the necessary space to turn from  
the constructive point of view. If this is not the case, the tires  
could rub against undercarriage components, the bodywork  
and the brake lines, which could cause failure of the brake  
system and the detachment of the tread, possibly resulting in  
tire blowout.  
— Never use tires whose actual size exceeds the tire  
dimensions approved by Volkswagen.

feel damaged and replace if necessary.  
The rims, tires and wheel bolts have been designed  
for the type of vehicle in question. Therefore, if the  
rims are changed, wheel bolts with the correct length  
and head must be used. This ensures that the  
brakes can work properly and that the vehicle runs  
with stability and safety.  
WARNING  
Loosening and incorrectly tightening the bolts on  
rims with bolt-on rims can cause accidents and  
serious injuries.  
· Never loosen the threaded connections of the wheel  
studs with screwed hoops.  
· Go to a specialized workshop for any work that  
has to be done on rims with bolt-on rims.  
Volkswagen recommends going to a  
Volkswagen dealer for this.  
For technical reasons, tires from other vehicles  
cannot generally be used. Under certain  
circumstances, this also applies to tires of the same  
type of vehicle.  
The tightening torque of the wheel bolts should  
be checked regularly with a properly functioning  
torque wrench ÿ p. 353.

Rims with a rim or bolt-on trim elements  
Rims with a rim or bolt-on trim elements consist of  
several parts. These pieces are joined together with  
special screws. Damaged rims must be replaced and  
may only be repaired by a specialist workshop.  
Volkswagen recommends going to a Volkswagen  
dealer for this ÿ .

Tire Tread Depth Most driving situations  
require that the tires have as high a profile as  
possible. In addition, the depth of the tread of the  
tires should be uniform in all of them, at least for  
axles. This applies especially when the road is wet  
or presents winter conditions.  
Damage to tires and rims is often not visible to the  
naked eye ÿ .  
— If you suspect that any wheel is damaged,  
immediately reduce speed and stop the vehicle  
as soon as the traffic situation allows it and it is safe.  
In most countries, tires will have reached the  
minimum authorized depth limit when a 1.6 mm (1/16  
inch) profile remains, measured in the grooves next  
to the wear indicators (note the specific legal  
provisions of the country in question). The depth of  
the tire profile should be uniform in all of them, at least  
by axles ÿ .  
— Check whether the tires and rims are  
damaged.  
— If any tire is damaged, do not continue the  
March.  
— Replace damaged wheel ÿ p. 352. If necessary,  
ask for the help of specialized personnel.  
Observe the legal provisions of the country in question  
regarding the minimum permissible tread depth for  
winter and all-season tyres.  
OR: seal the damaged wheel with the repair kit  
and inflate it ÿ p. 359.  
— If there is no visible damage, drive slowly and  
carefully to the nearest specialized workshop  
and have the vehicle checked.  
Tire Wear Indicators Tire wear indicators  
indicate if a tire is worn. The tires will have to be  
changed, at the latest, when the tread depth reaches  
the wear indicators.  
Foreign bodies introduced into the tire  
— Do not remove foreign bodies that have gotten  
into the tire if they have penetrated it!
