Tyre Markings

What you need to know

Many of the symbols and markings are required by law. What do the tyre symbols and markings mean? 

On the tyre sidewall you will find details including the name of the manufacturer, product description, construction type, production date and much more.

Legal requirements 

One of the most important is the ECE-approval symbol (a capital 'E' in a circle) followed by a number.

This marking is a legal requirement and confirms that the tyre can be sold in Europe.

Size designation and markings 

An example of the size designation and markings is shown below – see the tables below for the Load Index Code and the Speed Rating Symbol. 

205/55 R16 91V
205 Tyre width (nominal measure) 205 mm
55 Aspect ratio, the height of the tyre sidewall as a % of the nominal width
R Tyre construction: Radial
16 Wheel diameter: 16 inch
91 Load index: 615 kg
V Speed category: maximum speed 150 mph/240 kmh – see Speed Rating Symbol table below

Additional markings 

In addition to the size markings you will find other information such as ‘Tubeless’ for tyres without inner tubes, ‘Reinforced’ or ‘Extra Load’ for high load tyres and the letters ‘M’ and ‘S’ for winter or all-season tyres. An arrow indicates the direction of the tyre rotation on directional tyres and tyres with asymmetric tread profiles have markings showing which side should be on the outer side of the vehicle.

On the outer edge of the sidewall you can also find small markings, e.g. ‘TWI’ which indicate the position of the Tread Wear Indicators. These are raised areas at the base of the tread grooves which are a visual warning of when the tread depth of the tyre is approaching the minimum legal limit.
