Tyre Knowledge.

Tyre Knowledge.

Your tyres travel, on average, once around the globe and are your contact with the road. They are made of over 200 materials, including steel and artificial silk. And if they have the right pressure, they even save you money. Interested in more fascinating knowledge and helpful tips? You can find them here.    

When do my tyres need to retire?

Tips on all aspects of tyre care. What can you do to make your tyres last longer? Here are some tips.

You will find what your correct tyre pressure is in your Owner’s Manual and on your fuel tank cap. Depending on load, it may vary by up to 1 bar.       

If pressure is too high, power transmission is optimal only in the centre of the tyre, which means less driving comfort, the tread wears down unevenly and your tyres do not last as long.

Tyre pressure gauges can usually be found at any filling station. Since November 2014, all passenger car and SUV models have also been equipped with a Tyre Pressure Monitoring System. Check the pressure when the tyres are cold, where possible, and do not reduce it when the tyres are warm.

A tyre loses about 0.1 bar in three months, on average. If the pressure falls rapidly, it or the valve may have a leak. Keep an eye on it. If you have any doubts, head off to your Volkswagen Partner.


Tyre Pressure Monitoring System.

Less consumption. More safety.

An underinflated tyre will quickly cause tyre damage – the reason for around 40 % of all accidents involving personal injury. That is why we have been equipping all Volkswagen Passenger Car and SUV models with a Tyre Pressure Monitoring System since November 2014.  

direct system

Direct system


This is how it works:

  • A tyre pressure sensor is installed in every wheel.
  • It transmits information to a control unit.
  • The on-board computer displays the tyre pressure.
  • If the pressure falls, the system warns the driver.

Indirect system


This is how it works:

  • The system measures the speed of the wheels, not the pressure.
  • Depending on tyre pressure, a wheel covers a certain distance in one revolution.
  • This gives rise to the speed of the wheel.
  • The system calculates the pressure from the speed.
  • If the speed increases, the pressure falls and the system warns the drive

Models with an indirect system:

  •  up!, Polo, Golf, Jetta, EOS, Beetle, Scirocco, Touran, Tiguan, Passat, Sharan, Caddy, T5 Multivan
How deep should the tread of my tyres be?

Too little tyre tread.

Less grip.

Already with 4 mm too little tread, your tyre has much less adhesion on a wet road. Reason: The tread no longer dissipates the water correctly. Your tyre loses contact with the road surface. We therefore recommend 3 mm for summer tyres and 4 mm for winter tyres. Do your tyres have less tread? Don't take a risk - have new tyres fitted.

How deep should the tread of my tyres be?

The rough grooves of your tyres contain small 1.6 mm beads. You can see the extent of your tyre wear compared with them.

What do the numbers on my tyres mean? Tyre structure, rim diameter, maximum permitted speed ... Apart from the name of the manufacturer and the product, your tyres also contain many other important pieces of information.


Many layers for more safety.

A tyre consists of running surface and carcass.

Running surface
1. Tread
– for good road grip and for absorbing and dissipating water.
2. Jointless bandage – enables high speeds
3. Steel cord belt layers – optimise driving stability and rolling resistance.

4. Cord body insert
– for shape retention even at high levels of interior pressure.
5. Inner liner – makes the tyre air-tight.
6. Side strip – guards against lateral damage.
7. Core profile – improves driving stability, steering and comfort response.
8. Steel core – ensures firm grip on the rim.
9. Bead reinforcement – supports driving stability and precise steering response.
