Your tyres are one of the most vital parts of your Volkswagen. Here you’ll find all the information you need to understand yours better.
Since 1 July 2012, all brand new tyres are required to have an European Union (EU) tyre label. Discover the information they give you.
EU tyre labels give a grade for fuel efficiency, grip in the wet, and loudness when rolling.
Tyres with a higher fuel efficiency grade encounter less resistance from the road, usually by featuring a specially designed tread pattern or tweaks to the type of rubber compound they use. An A-graded tyre can save you up to 0.7 litres of fuel every 100 kilometres, compared to a G-graded one.
The grading system for how well tyres stop in wet conditions ranges from A to F. At 80 kmph A-graded tyres can bring you to a complete stop in less than 3 metres. An F-graded tyre may take more than 18 metres to do the same.
How loud your tyres are when rolling is indicated by how many soundwaves are next to the speaker icon, one being the lowest and three loudest.
The numbers on the side of your tyres tell you a lot about them. Discover what they mean.
In our example, we’re using a tyre with the following numbers:
225 – tyre width
The first three digits tell you the width of the tyre in millimetres. In this case, the tyre is 225mm wide.
45 – the height to width ratio
Sometimes called the aspect ratio, this number is the profile height of the tyre’s sidewall expressed as a percentage. Here the tyre’s sidewall is 45% of its width, which is around 101mm.
R – tyre design type
The R tells you that this is a radial tyre, the most common design found in modern tyres. Radial tyres are constructed with the cord piles positioned at a 90-degree angle to the direction of travel to give the tyre extra strength. There are two other design types.
D (diagonal tyre) – The cords run diagonally. D tyres must never be used alongside R tyres.
RF (Run-Flat tyres) – These tyres are built with a reinforced sidewall that allows you to travel at reduced speed in the event of a puncture.
94 – load index
The load index tells you how much weight your tyres can carry. The load index runs from 65 to 124 with a higher number denoting a greater weight capacity. A load index of 94 means you can carry up to 670kg per tyre. This capacity may decrease at high speeds.
W – speed index
Graded in ascending order from L to Y, the speed index tells you the maximum speed your tyres can tolerate. W means the maximum speed is 168mph.
Date of manufacture
At least one of your tyres’ sidewalls will have an additional four-digit number printed on it. Known as the DOT (Department of Transport) number, the first two digits tell you which calendar week the tyre was made in and the last two the year.
Every tyre is made up of a contact surface and substructure. They feature the following parts:
