When fitting a Golf 7, for example, six sizes are approved:
195/65 R15 - 205/55 R16 - 205/50 R17 - 225/45 R17 - 225/40 R18 - 225/35 R19
No matter your traditional tyre size, you can choose any one of these six sizes for your winter package, providing the load and speed index meet the minimum requirements of the car manufacturer.
Winter tyres with a tyre speed index lower than that of the original tyres can also be fitted.
A 205/55 R16 91V summer tyre (maximum speed: 240 km/h) can, for example, be replaced by a 205/55 R16 91H winter tyre (maximum speed: 210 km/h) or by a 205/55 R16 91T (maximum speed: 190 km/h) winter tyre.
In Europe, if you choose this option, you must attach a sticker to your dashboard reminding you not to exceed the speed limit.
