Tyres - dimensions

The car's wheels (wheel rims) and tyres have a certain dimension, see the examples in the table below.

The car has an approval for the complete vehicle. This means that certain combinations of wheels (wheel rims) and tyres are approved.

The dimensions are stated on all car tyres. Example of designation: 215/55R16 97W.

215Tyre width (mm)
55Ratio between tyre wall height and tyre width (%)
RRadial ply
16Rim diameter in inches (")
97Codes for the maximum permitted tyre load, tyre load index (LI)
WSpeed rating for maximum permitted speed, speed rating (SS). (In this case 270 km/h.)

 Warning

19-inch wheels must never be used on cars that are not equipped with the R-Design or Sport chassis options. The use of 19-inch wheels on cars with standard chassis constitutes a safety risk, with a risk of vehicle damage, and it impairs the car's driving characteristics.
